solarity said: Good job! I am amazed that you are getting 120lbs/week out of that set up.
You can also buy fire resistant spray foam, and even better "Insta stick" (Dow Corning) which is a cross between a really powerful glue and a gunned low expansion foam. Sticks dry wall up, insulation board to wood or itself and anything else to anything else. Not cheap but I built most of my farm with it.
Thanks! Ill have to check that out when I close in my workshop. Sounds much safer... I can fit about 450 lbs of sub per shelf and I have about 15 shelves. If I only switched to oysters and did one flush I could probably do around 200+lbs//week. Probably more if i switched back to supplemented cotton seed hulls again. It's pioppino and shiitake that are eating up all of my shelf space at the moment, keeping us around the 120lbs/week. (p.s. not ignoring your email just getting some info together.)

Great set up! Looks like a lot of work! I'm curious about the A/C setup. Most window units are set up to recirculate the air in the room so the air returning to the unit is already "conditioned" and the unit doesn't have to run constantly. What is the benefit of ducting fresh air from outside the GH then into the A/C? Is it to provide fresh oxygen into the GH? Just seems to me pulling in outside air in the summer is going make that A/C works it's ass off to try and cool. Please explain the "why" on this so I can understand. Thanks!

Yep it is for fresh air and to help keep the a.c. from clogging up with spores. I grow a lot of oysters so if I didn't re-route the intake it would probably crap out in less than a year. It definitely does NOT cool as efficiently, but I'm installing a second one on the other end wall at the start of summer. We're getting temps in the up 80's at the moment and I still keep it between 60-70F no problem. Ill really need that second unit once we got the upper 90's here in a month or so.

Ok because of the spore load I get it. Was wondering since I saw it yesty how the hell that was suppose to work. I know in grow rooms for "other things" ppl will mount an A/C somewhere and have to duct the exhaust air out in a stealth way but I have never seen fresh air being pulled in for the intake. Kinda like a car you usually have it on recirculate mode for cooling rather than trying to flash cool hot air from outside. Carry on.

I designed my system somewhere in between the two. I have a small 3'x6' x 9' high room, i.e. a plenum, where my window air conditioner will be installed. When the grow room needs to be cooled, the AC unit kicks on and cools the 3x6 room until it reaches 58 oF (this can be varied and I will have to play with it a bit to find the optimum temperature; it also depends on the AC unit specs), a fan kicks on blowing the 58oF air into the grow room. The 3x6 room air is being replace with fresh outside air. When the temperature in the 3x6 room reaches say 62 oF, the fan stops and waits for the plenum room temperature to reach 58 oF before turning on again. This repeats until the grow room is at the desired temperature, at which time the AC unit stops.
A similar system will be used for heat. Please keep in my I have not built or tested this system, but I think it should work well. The key will be determining the best low and high temperature settings for the 3x6 room. The advantage of this system is you only run clean air through the window AC unit. The 3x6 room will definitely be well insulated.
I was also thinking about putting the heating fan at the ceiling height and a separate cooling fan at the floor level.
Do you see any issues with running this system? The AC unit is well oversized, FYI, to prevent the unit from freezing.

I was originally going to build a plenum and do something similar, but it requires a little more tinkering and equipment to be effective.I subscribe to KISS so I try not to over build if I dont have to. A simpler solution would be to get a much more powerful unit, like a 24kbtu unit, and duct the intake the way I have it and that sucker would keep the room cool no problem.
If youre set on the plenum idea, just get a temperature controller (stc1000) to control when the a.c. unit and intake fan kick on and run a separate fresh air intake. I don't see any reason that wouldn't work just fine.

For shelving has anyone considered Unistrut? Mounted on both ends of the area, you could span your conduit shelves the whole length and they would be adjustable. Cant beat the strength and unlimited options with the numerous attachments and brackets,holders,configurations,ect. IMO You would have to look into it to get an idea of its applications. I am sure you could source some at construction sites if you asked the right person as well(If you didn't want to buy any)?

you would be surprised were uni strut can be picked up. re purpose construction material type places,Habitat for humanity,Re store,Scap yards. Now that its in your head you will see it every were.

Looking good! You should make your own thread detailing everything. I'm looking to make a small scale outdoor Fruiting chamber myself.

2 layers of 6mil blackout plastic with 4" of insulation sandwiched between them as well as a 70% sunshade to help protect it from falling debris.

Just installed the first two barrels on the new steam sterilizers. Going for 0psi 24ish hour cook for now. I am integrating prvs soon, but don't plan on running it at pressure. By my estimation I can fit about 40-50 bags per barrel. 260,000 btu burner run off propane. I am switching to electric eventually, but I already had the tanks and burners so what the hell. Here's some pics



Doing a test run tomorrow so we'll see how it goes!

beauty myco - are they all going to be heated by propane? I am considering building a similar setup with a single barrel soon. Good thing about this type of setup is that it's modular and you can keep adding on barrels. Is the first barrel just for making steam or is it also filled? Running pressure cookers gets old fast.
