Gr0wers Automated Greenhouse Build * 7
    #21708608 - 05/21/15 11:39 PM (8 years, 8 months ago)

Ill be documenting the build of my 24"x 36" HDX fruiting chamber. My goal is to produce enough mushrooms for my family to eat 2-3 times weekly and make some local sales to cover build cost. My substrates will be locally procured for free consisting of sawdust, cardboard, newspaper and coffee grounds mostly. I will be purchasing WBS for spawn and supplementing with brewers grain when i brew. The only supplement i will be using initially on the bulk substrate is gypsum at 5%.

The fruiting chamber will consist of a $50 home depot 24"x 36" five shelf HDX plastic shelf system. It will have the following features

- bucket humidifier running 24/7
- Self filling float valve from swamp cooler
- Purge pump to freshen humidifier water
- Overflow port and drain hose in the event of a reservoir overflow
- Ultrasonic foggers controlled by a digital humidistat for humidity boosting 
- 1.5" pvc air ducting/balancer
- Digital temperature controller
- Ceramic heater
- 4 13w Daylight CFL bulbs ( soon to be 4' daylight floros for even light)
- 3.5MM Poly

I will include a list of all parts needed to build this system once complete. Total cost is looking somewhere around $300, should pay for itself in 2 grows...?? hopefully!

Bounty from my Home Depot run





                HUMIDIFIER AND FRESH AIR  *******UPDATED******

After my kal cool mist started to fill with gunk and make funny noises i decided to go a cleaner route. A 5 gal pail or tote can be cleaned and sanitized much easier than a cool mist and should last years with proper maintenance. I'm running a push me pull you set up with fans, with a slightly faster exhaust fan than intake. This causes a slight vacuum on the chamber pulling any spores and CO2 laden air outside the garage under the door gap. I use two pails because the swamp cooler mesh is treated with a surfactant that kills the ultrasonic mist. There is a small hose that gravity feeds the swamp cooler from the ultrasonic bucket and the purge pump is located in the swamp cooler pail.

  $1 5 gal pail, used
  $8 Dial #4154 - Brass float valve w 1/4 comp fitting - Home Depot
  $4 DIAL #4296 - 1/4" x 50' drip hose $4 - Home Depot
  $2 DIG #C37B - 1/4 Female hose thread to 1/4 drip adapter - Home Depot
  $5 DIG #D46 - Garden hose thread drip adapter - Home Depot (or copper pipe piercing valve)
$24 Two AGPtek - Minti mist ultrasonic fogger - Amazon
$36 1.5" 36' pool hose- lowes
$10 Western Humidor Hygrometer - Amazon (wet towel calibrated)
  $3 50ft 5/8" drip hose for overflow( thrift store steal)
  $3  DIAL #92395 - Evaporative cooler overflow drain kit (Home Depot)
  $8 80 GPH 120v aquarium pump for purge (amazon)
  $4 GE #15119 - Basic timer (for purge pump)- Home depot
  $0 two small used PC computers with 6V power supplies
  $3 1.5"x2" PVC adapter for exhaust fan to exhaust tube fitting
  $4 two 2" pvc couplings, one for each computer fan.

FAE/Humidifier TOTAL $105
     


Swamp cooler pail with constantly recirculating water dripping onto the sponge material


Ulstrasonic pail with float valve



both pails, you can see i have the ulstrasonic pail on wood to raise the water level in the swamp cooler pail while allowing the ultrasonics to run with minimal water for better effectiveness.


Exhaust hose fan intake goes at bottom of grow chamber through a tape reinforced hole. All hot glued together.



                  AUTOMATION


$12 Carlon #E987RR - Junction Box - Home Depot
$16 Inkbird digital temp controller - Amazon
$28 Image digital humidity controller - Amazon
$10 #60025WF - 25 ft 16/3 extension cord - Home Depot ( cut off a few feet or get a 50' cord for wiring inside the box if you don't have spare wire like i did)
  $2 Two Leviton #R52-05320-00W- 15A duplex outlet - Home Depot
  $4 GE #15119 - Basic timer - Home depot
  $3 Two Pass & Seymour Model # SL8CC20 - 1 gang duplex stainless outlet wall plate - Home Depot
  $5 10 pack power socket plug 125V 15A - Amazon (hong kong 3-4 weeks mail time)
  $3 Amico M20x1.5 6-11mm cable gland (or 3/8 cable clamp from home depot) - Amazon (hong kong 3-4 weeks mail time)

Automation TOTAL $78


The socket plugs or the wall sockets can be used exclusively, when mounting to the top and bottom of the box the wall plates will not sit flush due to box design so i purchased a set of the socket plugs for a cleaner look. The socket plugs are the cheaper route but the outlets give you screw terminals you can stack 2-3 electrical connections to for splitting power. The socket plugs are a PITA to drill the holes compared to the wall sockets, I needed to trim the locking wings down since the boxes plastic is so thick. 

Settings for the controller should be as follows,

HC = H
D = 1 this is the one that matters for accuracy of RH%
LS = 75
HS = 99
CA = whatever your wet towel calibration calls for, mine was 7
PT = 0









                FRUITING CHAMBER

$50 HDX #128974 - 24x36x72" 5 shelf ventilated storage plastic shelving - Home Depot
$11 HDX #RSHD3510-25C - 10X25 ft clear 3.5 mil plastic sheeting - Home Depot
  $9 Gorilla #60035 - Heavy duty duct tape - Home Depot
  $1 #44241- SS positive lock hook and eye - Home Depot
  $8 six 1"x2"x8' furring strips - Home Depot
  $2 1x 1.5" hinge 2 pack - Home depot
  $7 1 1/2" x 10ft PVC pipe - Home Depot
  $1 1 1/2" PVC 90* elbow - Home Depot 
  $3 1 1/2" PVC Tee - Home Depot
  $1  three large zip ties for securing ducting to structure - Home Depot
  $1 1 1/2" PVC end socket cap - Home Depot



Chamber TOTAL  $102



Vent pipes roughed in (horizontal pipes were later removed due to condensation) I use loosely tightened large zip ties to hold the pipes in place, nothing is glued so i can disassemble and sanitize as needed.



some tetris to make the most of my poly



cutting the poly to size



taking down the door to wrap



wrapping the door



laid down the bottom barrier





                  LIGHTING

----------------------UNDER CONSTRUCTION------------------

  $9 4 pack 13W daylight CFL light bulbs - Home Depot


Currently using daylights CFL's plans to install 4' vertical mounted fluorescent daylight tubes for more even light distribution.




                  GROW CONTAINERS


At first i dicked around with 5 gal buckets only to find out they are hard to get pinset and a PITA to clean. I ended up using 4 XL grow bags per shelf with 10-14 lbs of pasteurized straw sub in each and had great results with side fruiting pinks like that. Im currently using this chamber for kings, nameko, maitake, shiitake in a rotation of sorts adjusting FAE and humidity for each species. They are grown on hardwood fuel pellets and bran in XL grow bags, 12-13 lbs per bag and top fruited except for the shiitake where i strip the block and just leave the bottom. 



as of Jan 2016 i just got my 55 gal drum steamer operational, so this should start being ran at full capacity real soon. 8 bags per shelf for kings, nameko and other top fruiters and 6 blocks per shelf for shiitake.



                  MISTING

TOTAL $6

I have an eye hook i hang the nozzle on when not in use.





55 GALLON BULK PASTEURIZER (edit) originally was going with a digital automated controller but found no need. I just set the thermometer to alarm at 150-5F with 40-45 gals of water, add substrate in bags reaching 145F and allow the temp to drop 3-4 degrees over 90 min. I use my sink hot water running a hose off the hand sprayer hose to fill the tank so it starts at ~120F.  It takes about two hours to reach operating temp.

$8 1500w hot water heater element- Amazon
free 55 gal open top steel drum, no lid so i made one with scrap wood
$6 1" SS locknut to hold element in place - Amazon
$1 1" PVC cap- Home Depot
$3 15A plug- Home Depot
$7 8' 12-2 cord- Home Depot
$1 Waterproof Cable Glands M20 x 1.5
$16 taylor digital timer/thermometer with temp/time alarm w/ RTV at probe/cable junction 
$24 six packs of 5 gal paint strainer bags for holding substrate- Home depot
free Random rocks to protect element from being bent, another one as a weight to hold the substrate bags down

$82 total







DONE!!!!

GRAND TOTAL $364 USD

While i'm at it i ordered a inkbird digital temp controller, basically a stc-1000 in F not C. Eventually ill have to start heating in the fall and winter and its much easier to wire everything once. Ill hook it up to run a small space heater. I have no plans to A/C the unit as of yet but the unit has a relay for cooling.

Thanks all!

I went on the small side to start with vent holes, I figured it's easier to drill bigger later than fill holes. I should point out there are holes on the opposite sides as well. I really should sit down and do some math of total inlet hose area vs total vent hole area and make sure its 1:1 or higher.

UPDATE: I just checked on the unit, looks like my super awesome vent distribution pipes are condensating on the outside and dripping, most likely due to the cooler wet air inside them. Looks like i may be removing the horizontal sections and just have the large inlets at the side. KISS takes the cake once again!

Its looking like my ultrasonic needs to pump 24/7 on low to maintain 90%+ i'll probably end up running it on medium fog when using the digital controller so it cycles. I also will probably end up getting a larger size humidifier that i can hack an expansion reservoir on and return the ultrasonic to my sons room.

I was up all night last night thinking about what growing containers i will use. I was considering using square milk crates, two on each shelf. It would be nice because i could spin them in place and harvest all the sides. My concerns are milk crates are probably not food grade or BPA free, and having an open bottom they will drip liquids and possibly contams to lower levels. I really hate the idea of using bags, as they contribute to operation cost and non recyclable waste. Any ides on good large size fruiting containers that are food grade and preferably clear to see contams?

Digital humidistat came in!! Hopefully i can wire it up this afternoon. The white cheapo extension cord will be replaced with a heavier gauge extension cord. This will allow me to plug it directly into the outlet 20 ft away. You gotta love minimum building code, one outlet in the garage! Best of all the mushroom chamber control box will be mounted inches away from the breaker box, with no outlet in sight. Too bad in in a rental. Man building code for garage is two gang 20A outlets on each wall and separate circuit on each outlet... IMO:)

Doing a quick salt humidity check before doing a damp towel calibration on the analog hygrometer and digital controller.  My white digital Oregon Scientific temp/humidity sending unit cuts out at 96% RH so the salt check is the only way to verify calibration. So far the digital humidistat is super slow to read. It's been 20 min and its still only reading 63%, it takes about 10 seconds per .1 interval increase. I've been keeping the Oregon Scientific sending unit outside the chamber so i can check the room temp/humidity from inside my house on a home weather unit. I have another sensor outside the house so i know when to open and close the garage door for cold air.



Vent ducts are now removed due to condensation dripping off them. I placed a drilled out cap over the lower outlet so the top elbow gets more flow.

RH automation complete!! Now to fine tune it. ( This shows my beta humidifier setup See OP for current configuration. )




Top hole is for the digital temp controller



How its wired up, right outlet is constant hot, left outlet has the black side jumper cut, isolating each plug. The bottom plug runs the ultrasonic, the top one will run the heater.



All cleaned up with zip ties

Are you able to explain the method you used to automate RH control?
I've been looking into this for my martha build, but haven't been able to find any decent guides

I've seen those digital humidity controllers on eBay. Will they turn on the humidifier once RH drops below a certain %? Is there a wiring guide somewhere?

Have your cool mist running 24/7 to maintain FAE and some humidity. Wire up the digital controller to kick an ultrasonic humidifier on and off to fine tune RH within 1% of setpoint. I purchased mine off amazon for $28. Amazon has a better return policy which can be important when i comes to cheap computer items from china, although i've never had any issues with these style controllers. I have one on my fermentation chamber for 3 years now no issues.

Real easy to wire up, give it power in from an extension cord on poles #3(black) and #4(white/neutral). Jump a black leg from #3 to #1, which will feed your switched power. The controller will turn power on and off at #2 so run a black wire to control an outlet or direct wire your humidifiers black wire to the unit, having the white wire on #4.

Dont forget to calibrate your unit once complete, mine was 6.3% low.

DISCLAIMER: I am not an electrician. If you do not understand wiring do not attempt this without a licenced professional.

That's awesome, cheers! I've been looking at automated RH setups for reptile enclosures for $150.00+ because I didn't think you could wire up those cheaper controllers to turn on/off accessories. Thanks for saving me some cash! :thumbup:

Glad to help!! Good luck and feel free to PM me with questions.

Thinking back now i could have included a digital timer to control an outlet for the lights something like this,

Inkbird Digital Twin Timer Relay Time Delay Relay Switch 110-220V Black IDT-E2RH

current config with digital controller, mounted lights, and without horizontal vent pipes


Once more, another change to the setup. While researching how to auto fill my ultrasonic, i had a light bulb go on!!! Why not install a fogger unit in my cool mist reservoir! Its already blowing humid air and the level is being maintained with the float. $12 later i have a unit in route to my place by weds. Looks like ill be fine tuning this unit Weds or Thurs deleting the separate ultrasonic humidifier and installing the temp controller. I'll be moving some of the power lines around inside changing the sockets functions. The left outlet will be ultrasonic on the bottom plug and cool mist on the top plug, cleaning up the external wiring a bit. The right outlet will be cooling on the top and heating on the bottom. The light timer will be moved to a individual plug cube that will be installed on the top. The current configuration of the light timer switch places the manual switch on the unit barely accessible facing the wall.

I'm considering including an inline swamp cooler scale eliminator water filter and small aquarium pump in the tank to serve as a purge pump draining the contents once a week. I know the ultrasonic units diaphragms scale up really fast on hard tap water. El Paso water is really hard so dumping out the reservoir via a purge pump would greatly reduce mineral buildup as the water becomes more saturated with hardness with mostly just the H20 evaporating. I will probably start with the scale eliminator and see if the purge pump is even necessary.

Sorry for all the rambling, sometimes its better to write it all down to help the thinking and planning process.

Just got the digital temp controller installed. Awaiting on a socket plug to be installed on top for the light timer. Should be here thursday. The RH sensor LED display is much brighter which kind of sucks since they don't match. So the right side sockets are for the humidifiers and left side is heat and cool.



Thinking about installing a 80x80cm water cooler over the cool mist air intake. I have a chest freezer right next to the unit for a cold glycol source. I could use a small aquarium pump in a container to circulate cold glycol water, chilling the incoming air. Ebay has em for $11 and i already have a small $7 aquarium pump.

http://www.ebay.com/itm/80MM-Aluminum-Water-Cooling-Block-Water-cooled-Row-for-CPU-heatsink-fan-/111426814091?pt=LH_DefaultDomain_0&hash=item19f18e408b

For the heating function I'm thinking about mounting a 100w ceramic heat emitter inside the cool mist? The socket would be mounted outside the unit with a rubber grommet on the hole where the shaft goes through. I will definitely need to check for melting and fire hazards and possibly downgrade to a 75w unit if its too hot, or consider other options. Good thing is i have months before i need to worry about heating.





Currently lining up a sale for 30 used 5 gal buckets for grow containers.

:thisisheavyman:
Somehow I missed seeing that float valve in your first post. Thats way cool. Definitely gonna look into rigging one up when I get around to making a proper humidifier & venting it to my grow room.

Right now I'm just rolling with a large bucket and 5 disc fogger with a fan blowing on it. It's a quick fix and works fine but I'm constantly refilling the thing. 

But I did just wire up one of those digital humidity controllers last week and popped it in a project box. Also wired in a little green LED light for when its kicked on as another visual reference. Once I figured out how to set the controller its been great. I just wish the probe/sensor cords were a bit longer.

Yea man its great. All i have to worry about when i check on my mushrooms is the mushrooms, the chamber maintains itself! That float valve is a $7 brass float valve for a swamp cooler. You can feed it via a hose bib adapter from a garden drip setup (cheapest and temporary) or use a piercing valve on some copper piping for a ice maker, then just run a 1/4 poly hose to the compression fitting, the whole thing is like $30 and well worth it. I dump the water weekly to reduce buildup and just recently added two balls from a bag of scale eliminator which has good reviews on keeping mineral buildup down.
I agree about the humidity sensors cord length, I could barely get it into my grow chamber. But the temp sensor probe is super long!

i would consider some kind of pressure reducer to feed the float valve.  mine blew at least once last year and boy did it make a mess!  it was overnight.

I had a 25 psi regulator at first and it was constantly seeping, shown in fist post second pic.Ill have to find a more rugged unit, the $4 home depot drip irrigation unit was crap. I do plan to install an overflow fitting above the water level with a hose running out my garage door. Then ill just have a flooded street instead of a flooded garage.

Let me know if u need any advice with wiring or settings. A cool mist should feed a room with 2-3 of these shelves especially with a larger air tube, if anything just put a computer fan over the filter hole for more air volume.

Is not enough lighting causing the long stems? My phone is measuring 90-160 with some free lux app. With the cool mist going 24/7 and the garage getting vented daily i cant imagine its from co2...???

You need way more fresh air, high Co2 causes long stems and small caps.

I installed a fan outside the box that blows fresh air into the corner of the garage. My suspicion is the air would recirculate out the box and back into the humidifier making the air stagnant. I also pulled the air filter off the humidifier for more airflow. EDIT: This proved effective

Regular oysters need very high fresh air exchange. One of the major challenges of growing them (well) is to maintain an appropriate temperature and humidity whilst keeping CO2 concentrations low. We are growing King Oysters which, though they have other foibles, are wonderfully tolerant of high CO2.

It seems the fan in the garage coupled with removing the humidifier air filter boosted the airflow substantially. So much that the humidifier can only maintain 85% humidity even with the ultrasonic going. I may have to dish out another $12 and run two ultrasonic disks running off the humidistat.

85% is fine for oysters, provided your reading is accurate.

Truthfully I'm finding the reading in general is super scattered and mixed advice across the forum. I have some that i'm trying to start pinning, or shoud 85% do it for pinset? I thought it was 95%+ for pinset and low 90s% for fruit formation?

Installed the second ultrasonic mister, seems to be doing the trick even with the dryest El Paso days. Just ate the huge cluster off the small blue tray, made three nice sized servings. Made it up with garlic, sliced almonds, olive oil and butter.

Updated OP, installed an overflow kit in the humidifier reservoir, moved the ultrasonic wiring to come through the bottom of the humidifier then hot glued the units in place and installed purge pump to exchange the mineral and dust built up water. The purge pump will turn on for 30 mins a day and pump through 30' of 1/4" drip hose, watering front yard plants in the process.

I realize now all this humidifier hardware could have, and can still, be installed using the bucket with a fan method. It would be easier to clean and sanitize when needed, not having all the nooks and crannies the humidifier has. It also would have saved me $20 on the humidifier since i have buckets and 80mm computer fans on hand. Using a bucket instead of a cool mist may require a third ultrasonic to run 24/7 in place of the cool mist.

Updated OP with 55 gal drum pasteurizer. Currently wrapped in pieced together bubble wrap, soon to be wrapped in wood planks for better aesthetics, it sits on my patio. I was looking for a plastic drum but this steel one is serving me well for now. I was going to automate the drum using a digital controller, i even made a nice control box which ill use for other projects. After using the pasteurizer a few times i realize its easier to use my taylor probe thermometer with temperature alarm to reach the operating temp then unplug the element and load my substrate, set the timer and walk away. There is really no need for a digital controller, I can allow the temp to drop 3-4 degrees and still be within the sweet spot for pasteurization.  The 1500w element works great for me. One to three hours of waiting isn't too bad vs wiring a 240V leg using a larger and much more expensive element, plug, and wire.

I remember reading on a brewing forum that the heat loss after flame out was basically nothing over the 1.5 hours it takes to mash your grain, something on the order of 1 degree F for every 30mins at room temperature. Insulating large mash tuns/pasteurization tanks is only necessary in high winds or very low temperatures.

4 year brewer here. I speak from experience that with naked metal vessels the heat transfer is rather fast. It also depends on your volume ie. a large tank with a large thermal mass and less surface area will take longer to cool down. I put two wraps of the crappy bubble wrap with mylar on my mash tun, about 2R value, and saw a huge difference in HERMS water in and water out temp. When i do BIAB, which the strike and mash process is essentially the same concept as pasteurization temperature wise, i always wrap a thick blanket around my kettle and still see 4-5 degrees drop over an hour with 8 gals water and 12 lbs grain. I think the idea with both pasteurization and mashing is you want to keep the temperature as steady as possible, but some drop is acceptable given you stay in the green zone. 

The point is the wife isnt fond of a 55 gal drum sitting on the patio, dressing it up with some wood would make her slightly more happy about my neverending mushroom projects.

Wow this is almost exactly like what I have. I mounted the ultrasonic foggers (x2) in a float each inside a bucket filled about halfway with water, lasts a few days. I have both hooked up to the same humidstat and I just got a cycle timer for my exhaust fan. Seems to work alright but is taking a while to dial in.

How did you calibrate yours?

I have a digital humidity controller on the ultrasonics. I'm still dialing in the new humidifier. Im having issues with aborts and dry looking fruits. I think the issue is when the foggers aren't running its sucking in super dry air, typically 0-20% RH. The old cool mist would at least help keep the humidity up. My fix will be a mini swamp cooler on the intake pipe. Im going to install a 4" 90 degree elbow going down where the 2" coupling now is. Extending down from the elbow will be swamp cooler mesh tube and a cap on the bottom end. Ill have a second aquarium pump running 24/7 soaking the swamp cooler mesh. Ill have to replace the swamp cooler screen every month or so but one sheet of mesh should make 4-8 refills. I'll hopefully make this tonight and update the post.

You might try dropping an airstone in the tank to give you constant low level humidity with the misters topping up as required.

I don't think an airstone would deliver the volume i would need for my chamber size and airflow volume. With my experience with swamp coolers it should bump the RH up 30-45% Im also looking for a temperature drop, its been in the low 80s during the day in the garage. This little mod should drop the temps 5-10 degrees hopefully. I went to home depot and ended up going with a 2" elbow and cap for the swamp cooler section, 4" was just too large for a 5 gal pail, maybe in a tall tote a 4" would fit. Ill rig it up tonight. Ill also have to bump up the fans power supply from 6 to 12v to boost the fan for the added restriction.

    #22012636 - 07/28/15 11:02 PM (8 years, 6 months ago)

fucking shit! I hooked up the swamp cooler matting with the elbow and everything. Went to see how well it worked and i realized my ultrasonics were working but no mist. After 20 min of cleaning and rinsing i came to a conclusion the swamp cooler matting has some sort of chemical surfactant on it. I'm soaking the matting in TSP 90/ oxyclean i use for homebrewing, hopefully that will break down and remove whatever chemicals are on the foam. I'm so pissed right now, i just left the grow chamber unplugged till tomorrow.

I think i have a plan, make a 2nd bucket with the swamp cooler water and purge pump. Have a water line going from the ultrasonic pail feeding the swamp cooler pail fresh water.  Have the air flow in the swamp cooler then into the ultrasonic pail via a section of pool hose.

Ok so two stressful days later i finally got the swamp cooler part working with the ultramists. I had to run two pails with the water flowing in the ultramist pail then a tube feeding to the swamp cooler pail. My purge pump is located in the swamp cooler pail as well as a second pump to circulate water over the swamp cooler mesh. Ill have performance results tomorrow. So far its running well, i may need to restrict the intake fan since its a larger fan than the exhaust.

Pics located in OP

With the recent upgrade to the unit and changing the fan power supply from 6 to 12V i should deffently have the airflow for a larger chamber. Once i start making some profit at the farmers market, hopefully next month, i will attach a second shelving unit and expand the chamber.

Could not understand why you needed so much humidity, but I just took a look at your pics with the buckets, I did not realise how small your chamber is (I work in metric !).

You are going to seriously struggle to get enough air flowing through that to flush out the CO2 and heat generated by even half of those buckets fruiting in such a small space. You will also have the whole thing clogged with spores very quickly - I assume you are ducting exit air outside and not into your garage!

If you can, expand the sealed in area by 3-4 times, does not need shelves just volume otherwise I doubt you will have any mushrooms of saleable quality. Though I feel you may be over estimating the production of such a small area and underestimating the cost of sales.

Great job on the automation, very neat!

Yes I am externally venting under my garage door. I've already had a few nice harvests off the bags around 10-14% weight yield. I'm growing phoenix oysters which seem much more
tollerant to co2 and heat. With 6 pails and 14 3 kilo bags the temperature
stays about 1 degree fahrenheit warmer than the garage ambient. I agree I need to expand my grow and I do plan to build a larger chamber in the future if sales go well. I've already registered my company and have the welcome course for the farmers market next week hopefully there isn't too much cost besides my stand

Got any pics of your mushrooms? I have just started with phoenix as an additional warm weather strain. My Florida Oysters are extremely CO2 intolerant.

Nice colour! They are heat tolerant though they are also known for a heavy spore load.

Very leggy though from too high CO2. I think you will have problems with that in your present configuration, especially when you have more than one block fruiting at the same time. This will reduce your quality, yield and sales appeal.

blues pretty much kick ass year round.  the browns don't have the shelf life or BE that the browns do.  plus browns pin under the bags like crazy while blues just pop out of the holes where you want em.

@Solarity, That grow was with the old cool mist FAE setup. The new bucket setup pushes about 2x the volume @ around 50-70 CFM (48 CF grow chamber). I'm currently getting about 1-2 exchanges per minute. So they should look a bit better. We will find out over the next week as my pails should be pinning now. If i want more FAE i have 120V 4" fans i can replace the computer fan with

@drake I haven't had any issues with my phoenix pinning inside the bags so far, might be the strain(s) you used?


I made a vid explaining the setup if anyone wants to check it out. Please let me know if the link doesn't work.

Solarity, you seem to be 100% correct about FAE. With the chamber this full the mushrooms are getting a little too lanky to make nice clusters for market. I think ill be stepping up the ducting to 6" ducting.

I upgraded my intake blower fan with great results. I went with a used 110V ac fan i had on hand. It pushes around 100 CFM and easily pushes twice as much air as my 80mm computer fan. Now i need to upgrade my exhaust fan to equalize the airflow. Im also now 2 degrees F cooler inside my chamber than room temp, previously i was 5-8F higher so this is great since my garage is always warm. It also is telling me the swamp cooler is working as designed. The air smells a lot fresher in there now. With my new batch of pails slated to go in next week hopefully my fruit clusters are tighter with larger caps.


blue thermometer is ambient temp, display is chamber temp.

Here is the unit im using, its a COMAIR ROTRON MX2B3 105 CFM axial cooling fan designed for servers and industrial computer components

Hey bro, I've been researching a lot about GH... And it seems you might give me a good answer since it seems your quite good with GH's.

I'm going to be building my GH soon, it will be maybe around 6ft x 3ft x 3ft..

I'll be making a bucket fogger, so I'm getting 1 head ultrasonic fogger (500 ml per hour), and I'll also get 2 fans (124 CFM, waterproof).

My question is... is the CFM of my fan too high? or is 1 head fogger not enough? Because I'll put one fan for the bucket and might also put the second one on top of the GH for more FAE, or should i just put one fan for the bucket and let it run 24/7 while the fogger on a hygrostat so that it turns on or off at the desired humidity

What do you think would be good?

100 cfm sounds about right for that size, it also depends how much substrate you pack into the chamber and what species you plan to grow. With small oyster grows with a lot of substrate you will need constant FAE for cooling and Co2. I would recommend running a second fogger, simply because if one fails you will still get humidity, and have a third on hand as a backup replacement. You will want one fan for intake feeding the humidity pail/tote and one for exhaust down low to pull the spores outside and away. I would highly recommend either having your exhaust fan accessible and easy to clean or install a exhaust filter to collect the spores.  I need to clean my exhaust fan and duct at least monthly or it will clog and seize due to spores. For your humidification mount the fan on the pail lid and have another hole in the lid with outlet duct running to your chamber or you can place the pail inside your chamber and run a fresh air duct feeding the fans intake.

Update to the grow chamber, i will be disassembling the chamber over the next month and integrating the parts into a larger 7'x7'x10' walk in grow room. The fans will be a 440 CFM IF6 VenTech 6" on a speed controler feeding the swamp cooler and 8" DF-8 for the exhaust with a large intake filter. All the ducting will be 6" and 8". The lighting will be 2 8' floros mounted outside the top of the chamber with a clear poly roof. I hope to place 30-50 pails in there, and upgrade my pasteurizer to a 300 gal tote and get an all american 41qt PC, or two. Ill start a new thread for that build/grow and link on this thread.

I've collected them from here and there, i find them in the garden sections. I only collect frogs and mushrooms and mushrooms with frog combos. At my house in MD i had them scattered all through the garden, its funny when ppl think they are real mushrooms.

I would mostly be growing cubes, reishi, and turkey tails... And a good thing is that my fogger comes with 3 free ceramic disks.

I might skip the exhaust fan though hehe, I'd rather clean the spores my self, cus the other fan i have is also 124 CFM and im afraid it could cause like static pressure or something (I'm not sure though cus this GH wont be fully closed or air tight)  if i have them both working (will it?) so i might keep it as a reserve.

One more question

I'll be making a border larger than the shelves with normal PVC piping and plastic sheet that (1.85m x 65cm x 1m) just so that that outlet of the humidifier doesn't touch the shelves... Should the outlet duct be at the bottom of the chamber or on top? (I'm guessing bottom cus humid air is lighter than dry air).
And also what size duct/pipe would you say i should get for the outlet?

Thanks!

With those varieties you shouldn't have too much of a spore issue. I have two inlets one at the top and one in the middle. My exhaust is at the bottom. You shouldn't need too much fae with those species so you can easily run your fans on a timer or restricted. The exhaust should be the same size or slightly larger especially if your not using an exhaust fan.

I  installed the IF6 on my existing setup. Freaking FAE monster! It's on a speed controller, i have it turned down to low and its a strong breeze in the chamber. With it on high its like a hair dryer coming out of the PVC ducts. This fan should easily support my larger 70 sq/ft grow and even larger to come.

So the one fan on the bucket should run on a timer best? Wouldn't that sometimes restrict the movement of humid air? cus my humidifier would be on a hygrostat (come with humidity control and a timer)

You shouldn't need constant fae especially on the order of 100cfm 24/7, run it on a timer say 30 min on 30 off or as needed. Your outlet should be the same size or slightly larger than your intake duct.

Just ordered foggers and fans because I'm tired of pulling out and refilling 1 gallon coolmist and ultrasonic humidifiers all the time, and because with my current setup it's difficult to keep both air and humidity up unless I want to refill those butcher every day or so.  :smile:

I'm going to add the swamp cooler addition too, in order to cool things down a little bit now that warm weather is coming up and I won't be able to drop ten degrees in a room by just closing the heater vent.  How deep is the water level in that bucket?  Does it matter that much?  It's the drip hose circulating water to the top of the pad that keeps it wet, right?

Also, I don't have an easy way to feed water into it, and don't want to have to refill often, so I'm considering using a 20 or 30 gallon garbage can full of water to feed everything through the float valve, does that seem reasonable?  I wouldn't mind dragging a garden hose through the front door to refill that part as long as I don't have to do it super-often, I just can't keep it continually hooked to a water source without doing a lot of plumbing I don't want to do.  :smile:

The water level is about 3", just enough for the swamp cooler pump to be submerged. I find using a sprinkler to work much better for swamp coolers, take a look at my other large grow room build.

A garbage can will work, But there's no way you can tap off a pipe or something for a constant supply? Im currently drawing off my laundry room, i put a Y off my cold water supply faucet. It only needs to be a 1/4 hose ran through the house.

Update vid on the grow. Should near 200 lbs this month on grey oysters alone. I already plucked 3-4 large clusters the day before off these six logs. Total harvest 24 lbs over 3 days first flush.

Those little boxes on the ends of the power cord are A/C D/C inverters. Each fogger gets its own inverter.

Main question I have as I think through my design now is the exhaust. You get by fine with just an inline filter before the exhaust fan?

I oughta just run the exhaust right out the window.

no filter on my exhaust, just a upside down bucket over it to protect me from dropping crap into the intake. I actually stopped using the intake filter too since i was having issues constantly balancing intake and exhaust airflow as the filter clogged. I think ill install a fine mesh screen i can clean to keep bugs out.

The whole grow is moving to a new location within the next 1-2 months, im moving to a 2 car garage house. With that i might revisit the intake, humidity and exhaust configuration.

Yea pushing the air outside your room even with a small Martha makes a huge difference with oyster mushrooms. And then there is the removal of hazardous spores from negative pressure.

The floor is graded to where all the water runs out under the garage door. From there an expansion joint soaks it up and sends it underground.

Got a pretty much identical humidifier setup being blown into an RV shower unit encased in plastic sheeting. The exhaust is passive, just a cracked shower window.

But, the good news, its been running for a few days now and I've got multiple clusters of pins forming on my test block! :awedance:

Trying new shelving. Used 1" conduit welded into a ladder then zip tied the horizontal bars. Ladder is 24" wide and shelf spacing is 15"  with 6" on the bottom shelf. I dont think ill use the top shelf unless i start using a step stool.

From watching your older videos it looks like you're trying different options and that stacking blocks wasn't working for you.  You'd previously used poly tubing logs but stopped, can I ask what issues you had with them?  I'm probably going to start with elm oysters and cottonseed or rice hulls until I'm able to get a clean room set up.

Also, do you reuse your poly bags?

Sterilized sub in short is better than pasteruzied. And stacking was stressing the bags and making the first flush smaller, typically around .6-.7 lbs. Im now seeing closer to a lb first flush with them on shelving.

It looks very nice...

Are you planning on a shelf on the other side of your grow room?

Also what is the cost per foot of the 1 inch conduit?

Its galvanized steel conduit. Where i welded i used rusoleum bright galvanizing spray paint. Cost per foot is .60 its $6 and comes in 10 ft sections. 3/4" is only like $3 but its nowhere near as rigid. Once the totem bags are flushed out ill tear out the totem support and build another set of ladders for the other side.

The only issue i can see from this is my misters. The bottom shelves arent getting misted. I could either hook up a high powered fan to circulate the air with the misters on or re design the fogger head configuration, with foggers on each shelf.

Do you have to spray the grow chamber interior down with a hose daily? I've seen both stamets and RR say this but they never say why.

I was hanging them with 550 cord then a zip tie that choked the knot. I would join the two bags with a 4" 550 cord loop zip tied to the top bag then choking the bottom bag knot.

No i dont spray the walls. I have the fogger go off every hour or so for 5 seconds and it wets the whole chamber.

What kind of wood is your current grow room framed with? The reason you spray the door at rr farm or staments is black mold bluid up. When i was running my humidifier 24-7 each month at the bottom of green house and the door had a bluid up of black mold. Im sure spraying every day is easier then scaping and bleaching once a month.

As always gr0wer, I really appreciate it. :thumbup: I've got a nice walk-in grow chamber in progress but no good way to install a proper drain. Should be ways to work around it. Have a "dry day" in the chamber every so often or something.

Wow steal how much did that cost. I alway use the rubber mats. With the water drip trays like barters have behind bars. Take out to drain once a week. I dont know what your set up flooring is rbalzer but what im planing on bluiding is the trays but bigger all across bottow and make a plug that pumps water out with a wine filter pump link to my laundry sink.

its a flat plywood floor raised a couple inches above the normal floor level of the room. One of the walls of the grow chamber is a window so if the water is nice and pools in one place maybe I could simply pump it out the window.

Really though I thought these setups weren't meant to produce much/if any condensation so I don't know why exactly this is a big concern.

New shelving is working out well. Just ordered more foggers to place under each shelf. That should help wet the lower rows and boost pinset and yield. so far my best was 1.6 lbs first flush off a 5 lb block, i also got a 2.7 lb cluster off a 10 lb block. I just bumped up the exhaust and circulation fan, they are a bit more lankey than i like.




Lions mane seem to like the soybean hull mix. I got a lb per 5 lb block, thats including my dumb ass misting them by accident and making the top 1/4 of all the clusters abort and turn brown. Ill be making a lions mane shelf for my next set of bags with poly to protect them from misting. I should see closer to 1.5 lbs per first harvest then.

Gr0wer,  can you point me in the direction for hose and fittings to run water lines between buckets and barrels? I want to add an evaporative cooler setup.

With no spigot for a water source, it's all blue barrel, bucket to bucket.

I package in 16 quart sterilite totes with holes melted in em and paper towels to soak up moisture.

No water? How do u plan to clean your chamber? You cant run a line out to the grow? For the swamp cooler all u need is a 1/4" dripline and float valve, then a purge pump (tiny aquarium pimp) on a timer for 30 min a day.

Let me clarify that it's a martha/automated grow shelf type chamber that is in my house. I have running water,  just not to that room. I am planning using a 30gallon barrel or tote for a reservoir and running tubing from that to the humidification bucket and then to the swamp cooler.

I don't what fittings or lines to get so that it's water tight.

For the drip line float valve it already has a compression fitting that clamps onto the hose.

swamp cooler works well the more dry the surrounding environment is - it cools the air through evaporation, while simultaneously raising the humidity. They are very efficient for dryer environments.

The humidifier does provide FAE but from my understanding the input fan on the humidibucket only turns on when the humidity drops below a certain level. Might not be enough considering the humidity will stay high with low FAE

It was explained that the exhaust fan is stronger in order to create a slight vacuum in the chamber. This does not make sense to me, since it should pull additional air through in through all kinds of open slits and cracks. Shouldnt it be the other way around, creating a bit overpressure inside like a clean room?

Yea, that would work if you want to push spores out into your living space. You want negative pressure so all the spores are pushed out by the exhaust fan. In the case of a cleanroom, all the air is clean so there is no problem pushing it out into your living area.

SHROOMSISAY01, do you have any sort of filter or scrubber to clean the air coming into your grow chamber? I have a negativity pressured chamber but find I'm concerned the air entering it is pretty dirty. I'm wondering about ways to make it a cleaner space in there.

You really don't have to worry about the air that much. Unless you live where it is very dirty. If the blocks are fully colonized they will not contaminate.

Gr0wer, your chamber is incredible and I hope to recreate it. However, the tek a bit hard to follow and doesn't include the construction of a few of the humidifiers and stuff. Is it possible for you to write a step by step tek? I know this is a lot to ask, but it would immensely help me and I'm certain other forum members get started with some higher level cultivation.
