 Greenhouse tweaks .... 
#10150753 - 04/12/09 07:47 AM (4 years, 1 month ago) |
|

So Ive been fiddling with my GH to get it set up for edibles and I have a few questions. Any suggestions about any of this is appreciated.
I know the traditional thinking is that coolmists provide air exchange and ultrasonics are more for humidity. However, if a guy puts the ultrasonic outside of the GH and pipes it in ... obviously its blowing air from outside the GH into it, thereby providing FAE. Question #1:So why the need for anything other then a ultrasonic piped in? If a coolmist is setting inside the gh on the bottom shelf as is so often recommended, its not doing much for FAE but rather recirculating the stagnent air. Ild think a ultrasonic outside, being piped in, would be doing more for FAE then a coolmist setting inside??
Also, the coolmist I bought has been keeping the humidty pegged at 99% (I have it sitting on the bottom shelf, inside the GH) but when I unzip the door flaps all the way to the top (to provide more FAE) it struggles a bit to keep the FAE up(to my surprise as it has no problem keeping the RH up otherwise.) So I bought an ultrasonic and am going to go buy some PVC and supplies today to get it rigged up. It puts off a nice solid stream of fog into the air as ultrasonics should, Im wondering though, question #2: Once I pipe it into the GH surely the condensation collecting in the piping will reduce the overall fog output?? I wonder if the reduction will be significant though? For those that pipe ultrasonics in, have you noticed a dramatic change in the output because of the piping?
It would be nice if I could simply pipe in the ultrasonic and get rid of the coolmist alltogether, and simply leave the door unzipped all the way to the top for FAE. Having the coolmist or the ultrasonic sitting on the bottom shelve takes up valuable space I could be using for blocks. Plus it soaks the bottom of the shelf right above it and anything setting on it.
The ultimate goal is to be able to leave the door of the 4 tier GH unzipped all the way to the top (but still hanging) for FAE and keep humidity above 95%. Im trying to figure out a way to accomplish this.
On another note, PitcherCabs blue oyster bucket got me thinking and Im looking around for 2 gallon buckets. Im thinking instead of doing blocks for my edibles, Ill just do lots of small buckets, remove the shelves of the GH, and stack them in it - one on top of the other. They are super easy to clean and handle and dont use huge amounts of subsrate individually, so disposal is made easy.
Question #3: If I did that I probably wouldnt need humidity that high and I can get away with the higher FAE and a bit lower humidity? Still around 85-90% or so?? At least I could do that for Reishi, Oysters, and lions mane. Ive never seen anyone do shiitake in a bucket (question #4: Have you?) So for shiitake maybe I have to stick with blocks Im not sure? King oyster and black poplar Ill just keep the very top shelf and put them in trays on setting on it.
I guess Ill just try to pipe it in and see how it works, I hate to start cutting the GH if I dont need to though. I did buy a nice INTERMATIC digi timer from HD for $16 that lets me set up to 48 settings per day in 15 minute increments. Also (SCORE) I asked the saw guy to empty out their sawdust container into a garbage bag I brought with me. Got 2 ten gallon buckets full of sawdust.
I was curious to see what you guys have to say about all this though... any thoughts about this are appreciated 
This is what I have kickin so far:
You can see its pretty humid in there
Pegged at 99%- But thats with the door zipped down.
Sporeworks Reishi blocks that arent doing shit.. no worries though I have a line on a fast fruiting reishi strain and am in the process of trading. Oh and a black poplar block I just put in there.
King Oyster tray that just got put in as well -
The coolmist chillaxin
.... and heres the new ultrasonic getting tested before I figure out what Im going to do with it.
I would like to be able to leave the GH unzipped like this, and preferably get rid of the coolmist off that bottom shelf completely so I could stack 2 gallon buckets inside the greenhouse. Ill leave the top shelf in tact for black poplar and king oyster trays (I guess if I have to use blocks for shiitake they will have to go up there too.) but take all the others out and take the middle support bars out. Hopefully it will be able to keep the RH up. Im worried that if I pipe it in, it might not be able to keep the RH up since the walls of the pipe will probably decrease the humidity output. ...
What do you guys think??

IT pisse me off that they call those Cool Mist when they are No Mist. Luckily I check to make sure I'm getting an ultrasonic.
The others are BS as far as I'm concerned.

Ya I got the ultra sonic all rigged up and piped into the GH.
Tweaking out the timers and such as we speak.
Man, I noticed one thing though. My whole GH is COVERED in mineral deposits from the tap water. A f***ing layer over everything! That cant be good for the fungus ... guess Ill have to use filtered from now on. What a PITA.

nice GH! but one thing ive had the same hygro/temp meter as you and the screen WILL go blue so best thing to do is do what i have done here 
wich is extend the sensor leads and make the display remote its simple to do with a soldering iron and hard to screw it up and best of all....easier to moniter temps and humidity!...but for this mod theres 2 sensors ones white with black squiggles on it with 2 leads(hygrometer sensor) and another that looks like a small LED bulb with 2 leads (temp sensor) then just use some wires and extend the sensors! and use soldering iron tip to melt some indents for the wires so when u close it up it looks halfway decent...hope i helped somewhat

Good tip! So far its hanging in there .. but yes, Ive been waiting for that to happen. Its funny that they make digital hydrometers ... but being in 99% non-stop is not good for anything... digital

Hmmm .... well heres what my king oyster tray and black poplar block look like. They are getting WAY to saturated arent they??
The black poplar block even looks like it was getting ready to pin but hasnt done much recently ...
I dont really know what to do about it though, my timer only goes down to 15 minute increments and the ultrasonic doesnt have an adjustment of any kind on it.
???????

Ozz, I would recommend spending the $80 or so for a repeat cycle timer. It seemed like a steep investment to me, but its sooo much easier to zero in on the humidity level I'm looking for.

I hear ya ... Im probably going to have to break down. Ive just spent more then I wanted to so far already.
My timer only goes down to 15 minutes increments. I have it set at 15 minutes on every 2 hours which is pretty close to right on but not quite. RH stays at 99% for over an hour .. about 1 hour 20 minutes or so then starts dropping. Sometimes it only drops to 89% before the next 2 hour cycle is up and the ultrasonic kicks on for another 15 minutes .. but some times it drops as low as 79%. Everytime the ultrasonic kicks on, however, it gets it back up to 99% in the 15 minutes it runs, no matter what the RH dropped to so thats not a problem.
In actuality ... the GH is only at humidity levels below 90% for 20 minutes or so every cycle. That should be ok dont you think??
10 minutes on every 1.5 hours would be perfect - or 5 minutes every hour even.
Im not sure if it will hurt anything though having drop in RH for such a short time.

I doubt it. I'd be more worried about the water pooling. Maybe you could solve the problem by increasing airflow? Have you tried leaving the door flap open?
But a good timer would solve both of those problems.

Yes, if I leave the flap open it gets WAY to low in RH... and fiddling with the timer to make it come on more then what I have saturates things to much. Its pretty close to perfect if I could just drop the timer to about 10 minutes every 1.5 hours Ild be set.
Maybe Ill just cough it up and buy one...
Have one you recommend? Preferably under $100. $80 is better ... lol

Screw it .... I just ordered it. lol ...
Hope its worth it ... looks pretty nice and I can think of a lot of applications it could be used for.

I'd get rid of that tiny GH and build one that's bigger out of pvc and plastic sheeting. I like having the coolmist on the bottom, but you don't want it blowing up through shelves. I just put together a mini greenhouse the other day and it only took 20 minutes to build. I put four hooks in the ceiling and suspended a square made from PVC from the four hooks, and then draped plastic sheeting over them and let them hang like shower curtains. I put my coolmist inside a tote that sits beside the shelves where the substrates are. The tote catches any mist that settles back down so it doesn't make a mess. This lets the coolmist shoot straight up with no obstacles for the mist to condense on. The substrate blocks on the shelves stay right at 95% humidity and the slits from floor to ceiling give all the FAE I need.
It's only a temporary GH. I'm building a 40' cave into the side of my mountain as soon as the snow melts and the ground thaws out.

Interesting. Im assuming the coolmist runs 24/7 then??
Have any pics? Im curious what shelving your using and what the total cost was. Sounds pretty inexpensive.

Some ppl live in an apartment so they cant do this.

When you say slits from floor to cieling how many are we talking about?Im still getting my portable greenhouse together and was just going to put 6 -1" round holes on 2 sides.2 for each side for each shelf.Think thats enough
@Ozz..Thats the same one I might be getting.I was going to order it tonight but Im waiting on someone getting back to me on a IGS-010.

Now I need a decent damn hydrometer, mine is acting weird.
Either that or something screwy is going on with my room. At night any time after about 4 PM ... the RH stays all the way at 99% and just barely starts dropping below 99% at the 2 hour intervals I have it set on before the ultrasonic kicks on. In the morning and during the day, it gets down to 79%
Weird ... lol ... I guess it must be because of the sun coming in the window hitting the GH, must drop the RH quicker.
Anyone know of a good... cheap hydrometer that will stay accurate up to 100% ??

A 20F rise in temperature cuts the relative humidity in half, assuming the same amount of water in the air. That's why you see it drop during the day.
People in apartments can put hooks into the ceiling. Everyone has houseplants. When you leave, simply remove the hooks and dab some white caulk into the holes and they'll never notice.
I use plastic shelves obtained years ago from a hardware store. I believe they're rubbermaid brand. My GH cost a total of about $20 to make, and that included the plastic sheeting. Of course, I already had the plastic tote the cool mist sits in and I had the cool mist itself too.
I'd be embarrassed to take pictures, because it looks so ghetto.  The floor is just a sheet of plastic and the sides are just hanging from the top. Nothing is sealed. It gets PLENTY of FAE and since the only drips are coming down right under the cool mist, the tub it sits in catches all of them. I run the coolmist all day, but turn it off at bedtime because the noise bothers me.
I only built it because I'm doing a workshop at the county conservation fair this weekend and I needed some fruiting projects to use as demonstration material. Anybody who lives in or near Eastern Washington state is welcome to attend. The fair is at the Ferry County Fairgrounds in Republic, WA from 9AM until 1PM. My presentation is at noon.

Sorry for hijacking Ozz.
Roger, you dont use a timer?I thought you used a timer on for 7 and off for?
Take some pics..I promise we wont laugh..Cause if it works then theres nothing to laugh at.

I have a cycle timer, but haven't dug it out of storage yet. When I lived in Seattle, I had a larger mini-greenhouse with two cool mists, and they were on a timer. This one was only built to use for two weeks, so it's super ghetto. I just let it drip, and catch the drips in that tote. If I planned to run it permanently, I'd put the coolmist on a timer. It definitely runs longer than it needs to.
I now have my entire dining room and about 1/3 of my living room stacked with colonizing substrates. I'm going into commercial growing, and am just waiting for the snow to melt to get my mushroom cave built. As said, this greenhouse is temporary, but an example of how cheap you can actually build one that's large enough to use rather than buying a 'martha' type that really doesn't have much room.

I agree, it would be nice to have more room for sure. However, I dont have a bunch more room to use at this time. Although I probably could use about another 12" in length and 6" or so in depth. For now though, I dont need much more (I dont think) to grow what I want to grow.
I wish I wouldnt have spent all this money now...lol.
Of course, that amount includes the new coolmist as well as an ultrasonic so I guess either way I would have chunked out a little.
Ahhh well ..... the timer will get me up and running and be exactly what I need.
