As you mentioned, I'll start with the manual swish method-- at my small scale I can't justify the expense of a mag stirrer right now as I'd use it too infrequently to warrant the expense--

I will be tapping your brain on how you use the vacutainers as long-term LC storage in the coming weeks too-- that's one of the most interesting things that I look forward to having the ability to do. They're plenty small, so I can conveniently get away with storing a couple innocuously in the fridge for long periods :smile:

I'm curious about the effect of FAE (rather, the CO2 level, which it seems nobody measures because cubes largely don't care).

A FC like jcm's has a lot of air turnover, somewhere around 4-8x per hour. Whereas from what I've seen of yours (Blue Helix) the only new air comes in via the fogger, and of course also through whatever gaps/leaks may exist in the walls. This must cause a big difference in average CO2 levels.

Of course the average won't necessarily tell the whole story- you've mentioned not pointing the internal air circulation fans directly at the trays, so the local-substrate CO2, especially after the start of fruiting could be much higher. But I'd still expect a big difference between the two FC styles. Is this something you've ever considered re: pans?

Maybe I'll post about to make a magnetic spinner for $10 next at the precisely correct spin speed for this hobby (not that super fast crap like the guys who put a magnet on a PC fan).  The truth is, I wouldn't spend over $15 for a magnetic stirrer either, but it doesn't cost more than that if you know what you are doing.

CO2 levels rising is almost a myth.  If your chamber is that crappy, you let me know because it would take serious talent to rise CO2 levels.  Mostly FAE in general is a myth.  You want so little air exchange that even bringing air in from the outside is debatable at all since the chamber will have cracks in it that draw new air in and allow the old out.  What is not a myth is INTERNAL AIR EXCHANGE. 

What is internal air exchange?  That's when you move air extremely slowly inside your chamber.  I use a few PC fans hooked up to some old power cubes from junk I threw out.  I never toss a power cube like the kind you plug into the wall.  I have probably 40 of them now that I've collected of all voltages, DC, and AC.  Most PC fans--which I mostly snag from broken stuff but have bought for a few bucks each too--can be operated from around 6V to 12V DC.  I like to operate them at the lower voltages unless they are the type that are "silent" which really just means they set the RPM lower using a resistor in the path (equal to setting input voltage lower is all).  I also have bought a couple of these USB clip fans without the annoying plastic fan blade guard that work nice because they have this adjustable pole they are on (I paid $10 for 2 of these at the time):

https://www.amazon.com/ARCTIC-Breeze-Mobile-Flexible-Portable/dp/B003XN24GY

My point is this: FAE is a myth for the most part and something that a fool chases to bring down CO2 when CO2 never rises if you have internal air exchange in the first place.  Internal air exchange is where it's at, and cheap little PC fans can be put in the fruiting chamber for that.

As far as feeling their air moving inside the chamber, if you can feel it right over the casing soil with your hand, it's too much.  You want to move air, not dry out the casing.

Here are 3 perfect in-chamber PC silent (i.e. low RPM) fans (0.23A, 12V DC) perfect for a chamber:

https://www.amazon.com/uphere-3-Pack-Computer-120mm-Cooling/dp/B072LDYKQ6

Here're two 12V DC 1A power cubes for you for your chamber (a single one of these can run all three fans by the way):

https://www.amazon.com/ALITOVE-100-240V-Converter-Security-Surveillance/dp/B082D7W362

Now your entire chamber's fan situation is solved for less than $25 for forever with 3 fans and a backup power supply in case you blew up one of them somehow.  Of course you still need to strip the wires and twist them together, but I assume most people can figure that much out.

Make sure you buy those 100 vacutainers for $16 at Walmart Pet Pharmacy through the link I sent.  You will never find a price like that anywhere else.

Vacutainers are super easy to use.  They come sterile too, so you just poke the needle in the cap and they'll suck your LC right in there.  You might have to pull the plunger back to get rid of extra air in there before you pull out the needle.  That way they never pop off during say a low pressure event (like a big storm).  Let me know if you need any help with them, but they are pretty simple really.

Also you can reuse them almost as many times as you want.  You got to dry them and pull the extra air out before you pressure cook them to resterilize them is all.

I did! They were I think $21 shipped :smile:

And I'm all ears on the DIY stirrer-- (you should really make a journal post with all your TEK's brother -- you have such a wealth of good info that would be a great collection if put in one place)

Cool. I asked because I've got a couple of reishi blocks fruiting in separate but mostly identical chambers. One is growing antlers, the other started growing conks. One of my tubs is clearly leakier than the other :smile:

Very handy to know, because I'm worried about the amount of moisture the jcm-style FC I'm building will send into my room. But if internal recirculation and some minor leaks are all that's needed, I can rig something up to keep the air mostly closed-loop. Will be an interesting experiment anyway, if I manage to grow anything other than mold.

Will be an interesting experiment anyway, if I manage to grow anything other than mold.





How about this: try it and see.  Here's the thing: for the vast majority of chambers I've reviewed, the amount of leaking air is plenty provided they maintain internal air circulation.  I've actually seen people airing out their Martha Stewart style chambers with a bathroom fan!  That's just plain stupid.  The mushrooms do breath oxygen--that much is true--but look up how tiny the amount.  On page 183 of "The Mushroom Cultivator" by Paul Stamets, the books says that pan cyans require 2 air exchanges PER HOUR (I'm sure this figure is highly conservative too in that I bet they'd do fine with one per hour).  If you really think your chamber, with internal air circulation, isn't getting a replacement of the air each hour or two then add a bubbler like jcm4620.

Mold, by the way, has very little to do with fresh air exchange. That's another old myth. Mold has nearly the exact same environmental niche that the mycelium we want does.  It is true that it can survive lower fresh air exchanges than say pan cyans does, but it doesn't do any worse with ample FAE.  Mold likes stagnant air more because it likes 100% RH best (can be a micro-climate too), not that it enjoys CO2.  Still our prepinning pan cyans also loves 100% RH.  In fact you can peg it at 100% until pin development without a problem, and even then it can tolerate 100% RH during fruit development some say (it only stunts growth a tiny bit if at all). 

So you fear mold, right?  There is no need to do that.  Instead, ask yourself this one simple question: are there uncolonized portions of the substrate or casing that are very wet for an extended period of time (say over 3 days)?  If there are, then the mold spores that you breath in with every waking breath, that are all over you and your grow chamber (unless you happen to live in an industrial clean room) will take hold on that surface.  If not those mold spores will going all the rest of them as mycelium food.  Let me give you an example.

In this thread I light scratched my casings to get rid of overlay, soon after the trays promptly all molded.  Why?  Because the mycelium was too weak to take hold of the mycelium I broke up again (to reconnect with it) so the fragments and casing became mold food.  That's all that happened.  If it had been cubes, the mycelium of the substrate would have reached up and reconnected faster than the mold could grow and there wouldn't have been a problem.

Hey blue helix, this is a late response to my question (LC) yesterday but wanted to thank you anyways. I wasn't trying to shit on LC's. I have been doing this stuff for like 5 months and don't know everything yet.

That's why I posted the question, because on one hand I've heard LC's are tricky and contam quickly. But since you're having great success as a TC with them I figured you'd be an, if not the authority on LC's and I should probably ask you.

Anyways, thanks again and I hope to one day understand LC's and give them a shot, but that's another project. I just got LME and actual agar plates that work (thinking of writing a grow log so people can learn from my failures) so I'm starting to work with that now and LC's will be next after I get some pan fruits.

Thanks again man and sorry if my original question was too stupid

blue Helix - Ive read through many of your excellent logs and really appreciate all of the detail you've put in to them. I'd love to know more in depth about how you set up and dial in your fruiting chamber. Iv gathered bits an pieces (especially above concerning internal air exchange),and would really love to learn more about your setup as I believe this is where Ive been running into problems.

Of course the average won't necessarily tell the whole story- you've mentioned not pointing the internal air circulation fans directly at the trays, so the local-substrate CO2, especially after the start of fruiting could be much higher. But I'd still expect a big difference between the two FC styles. Is this something you've ever considered re: pans?




Sorry, I forgot to answer this.  Okay, speaking of jcm4620, he does have more FAE, but it's not as much as you said.  That's because my chamber does introduce a tiny trickle of air when the humidifier is off (at all times really).  That was accomplished by taping a PC fan on the input vent size of the ultrasonic with gaffers tape (which is just a cloth no-goo version of duct tape):



Here's the a 1" PVC pipe with small holes drilled in it running down the length of one of the three shelves (each one can hold up to four 9"x13" glass trays - which is several times as big as needed for me):



So while I'm sure the vast majority of air is introduced by the simple internal air circulation (which I promote with multiple PC fans) also a tiny trickle of air is pushed through the PVC tubes and released over the trays.  Now, note, that you sure as hell cannot feel it with your hand but you see the effect of it via the mist when the humidifier is on by cycling on and off the PC fan.  The PVC insides tend to have water on them even when the ultrasonic is off because it cycles on so often, so it's not like super dry air ends up being released over the trays.  It is far wetter, though, when the ultrasonic is on since mist hits the insides of the PVC than off and the mist particles are released, but the fact that drier air comes in when the humidifier is off is a GOOD thing.  You want to be able to keep the RH below 100% too!  Actually that's the hard part - making a chamber where the humidity doesn't just peg to 100% or swing super high and super low all the time because that will dry out your casing soil and you'll constantly be fighting it.

I don't have a way to measure CO2 levels other than the expression of the fruits themselves.  What I look for are stems that seem unusually long when I know the phenotype isn't like that.  What I mean is sometimes fruits are long just by genetics, but that is usually not the case.  I know cubes are often touted as being bullet-proof, but in my experience some of them are sensitive to higher CO2 and elongate if they are kept in it (like say in a tote without much circulation).  So when I grew those strains of cubes (Mazatepec was like that) I made sure the stems did not elongate in the chamber.  The same applies to pan cyans: there are phenotypes that are longer genetically, but if you are seeing super log stems when no one else is, the problem is probably your chamber's excessive CO2.  And I don't see lengthening of the fruits in my chamber, so I think I'm good.  You want the cubes to look like this (these were Ecuadorians by the way - such a nice strain!):



By beef about a lot of chambers is simply that too much fresh air is introduced OR not enough.  Sure you need _some_ fresh air but pan cyans, for example, are rated at 2 per HOUR according to Paul Stamets's masterpiece "The Mushroom Cultivator"!  That's not very much in a small chamber of wire shelves.  And when you introduce too much fresh air, most chambers will have large humidity swings or the humidity will peg at 100% - neither are good things to happen.  It's a delicate balance in there, and unless you are getting hints that the CO2 is too high, don't fix it if it ain't broken is my philosophy.

You mentioned about the shelves being stainless steel: hell yeah that would be nice!!!  However, I looked at stainless steel options and they are EXPENSIVE AS HELL!  There was no way I was going to pay $800 or whatever they costed, so I got some old server rack shelves from an auction for next to nothing (like $35 for that unit if memory serves me) and said the hell with it.  Yes, they have rusted horribly over the years.  Yes, I will never be able to use them again when I move and might even need to take a grinder to break them apart for disposal.  But that's not a tragedy at $35 for the unit, and the mushrooms couldn't care less about that.

Now having rust might encourage mold spores to sick in it (I don't know really), but I have a solution for that too.  Each time I finish a grow, I ozonate the chamber with this (which I think I paid $45 for on eBay via an open box) for about 20 minutes and let it dissipate:



Given how small the chamber is, 20 minutes of a 5000mg/hour ozone unit like that is like HUNDREDS times the concentration and length of time needed to be ozone sterilized. Nothing survives that I'm sure, even insects like mushroom gnats or larvae hiding out in there.  It basically sterilizes everything if my calculations are right.  But it's not long enough to ruin the plastic and furniture wrap covering, so I'm good.

Thanks for the compliments, but nowadays everyone seems to be pumping out beautiful pan cyan, cambo, and tropicalis canopies!  When I started (back when there were dinosaurs and civilization hadn't formed yet) it wasn't like that, but it looks like to me that many people have settled on techniques that work for them.  And not all (maybe less than half) are using LCs, so it's nothing about that or my earlier grow logs.  It's more tha people are paying attention to detail and listening to what their grows tell them.  I like LCs, of course, but I'm not egotistical enough to even start to think it's the only way (or even the best necessarily).  But no matter what way you grow, you have to listen to the grows to zero in on what works for you.  I also think that nowadays those who are using agar are helping weed out the genetic train wreck this hobby was leading to.  I'm thankful for those who do that too because I don't like doing it personally.  I'd rather just enjoy the literal fruits of their labor!

just wanted to add that while i do have a constant far there is no air movement inside my fc other than the updraft created by the air bubbling thru the warm water and rising up and out while its there you cant feel it at all. i dont have any actual moving air but for the fan thats outside just pointed twd the tub that comes on every 3 hours for 2 min. i do have a ceiling fan that runs on a low setting tho 24/7 just to have a slight circulation of air cuz that door stays closed as a precaution against drop by visitors and i hate stagnate air

blue Helix - Ive read through many of your excellent logs and really appreciate all of the detail you've put in to them. I'd love to know more in depth about how you set up and dial in your fruiting chamber. Iv gathered bits an pieces (especially above concerning internal air exchange),and would really love to learn more about your setup as I believe this is where Ive been running into problems.




Well, what do you want to know?  Here are some pictures for you, okay?



Below is a summary of some of the key points to the chamber:
  • The chamber is made of four 4'x1.5' (48"x18") wire shelves (three to put trays and the top as a ceiling. 

  • The shelves are covered with reflective bubble insulation on the three back sides.  It's kept in place via hot glue blobs.  The top and front faces are furniture wrap draped over.  The front is secured with some side magnets for easy access.

  • I use a home constructed temperature/humidity combined controller via Dwyer's offerings (for more details on how to build one yourself, see this thread : https://www.shroomery.org/forums/showflat.php/Number/26854793 )

  • heat is provided via a 40W red bulb (doesn't matter the color but the red bulb doesn't light up the whole room which I liked).  On the shelve above the heat bulb, there is a layer of insulation and when the heat bulb is on to protect the bottom trays and a PC fan blows on it as show in the pictures.  The heat rises and is distributed by PC fans.

  • When the controller turns on the ultrasonic or I turn it on via the override timer, mist enters the chamber through the PVC, is distributed over the trays very slowly via the PVC tubes, and raising the humidity.  When the ultrasonic is off and at all times really, a tiny trickle of outside air enters through the PVC via a fan that is taped on the humidifier's air input vent.  So when the humidifier turns off the humidity in the chamber settles down very very slowly.

  • Internal air circulation--which is the circulatory system of the chamber--is provided via two adjustable USB clip fans.  And--I just added this--two more PC fans on the top shelves blowing up.  So I have like four fans in there, but they are all running silently (lower voltage than their rating).  No fan ever has pointed on the cropping surface directly, though, and that is a BIG deal.  The fans help move air around the chamber, and I verified that by watching the ultrasonic mist move along.  My belief is that the internal air circulation promotes air from the outside in via the cracks around the furniture covering, etc. but if you point any fan directly on a casing, you will ruin your yield in a hurry because even at 99% RH that would dry out your casing.  If your casing is drying out in a couple days and there is not a flush coming in a day or so to explain it, something is wrong in your chamber.  The only time a casing might dry out a little is before or after a heavy flush; otherwise, it should be keeping its moisture pretty well (although a TINY bit of evaporation off the casing is a good thing)

  • Now this is a total luxury, but I run two dimmable Toggled brand full-spectrum 5K ("sun light") 4-foor T8 tubes on a dimmer (see https://www.homedepot.com/p/toggled-48-in-16-Watt-Daylight-Deluxe-T8-Dimmable-Linear-LED-Tube-Light-Bulb-2-Pack-D416-65321-2/308086234 ).  The bulbs even have built-in reflectors and will last a lifetime.  They are water resistant too, although I did cover the ending prongs that I soldered to with epoxy putty just so no one touches it doesn't short out on the shelves or something like that.    Usually the dimmer is turned at least haf down, but even when it is not, the tubes do not release enough heat to overheat the chamber.  I like to turn them up for pictures.

  • Speaking of electrocution, I actually have live wires sitting outside the chamber because I never boxed the light dimmer, so I take the fact that this unit is powered by a GFCI seriously, and you should too.  Get one of these https://www.homedepot.com/p/Husky-Wall-Adapter-GFCI-04-00106 ; So $14 to potentially save your life?  Doesn't seem like much of a "choice" to me.

  • I bought 12 13"x9" Pyrex baking pans for like $4 each at various garage sales and at the thrift store.  I reuse them over and over.  The shelves can comfortably fit 4 per shelve (so 12 of them).  8 trays happens to be 20 pounds of substrate which I can fit in the AA921 if I want.  However I very seldom run that many trays because I have no reason to do so (and it's kind of sad to throw away all of the extra).  Two trays is plenty to get a decent biological efficiency computation, and that's my favorite metric of success (not the pretty canopy picture most people prefer over everything else)

Temperature and Humidity Settings
The chamber is kept at 78 to 80F at all times.  The humidity is around 98 to 100% before pinning with ultrasonic misting hours cycles each four hours (but the ultrasonic output is so super restircted with those pipes that that isn't much water to be honest). So that's a basic run down.  After the fruits are about quart height, I drop the relative humidity to about 95-90%. 

Well, I hope that wasn't too much explanation for you, but I don't know what else you'd want to know.  Just ask if you have questions.
