Here is my new Gorilla Tent, with a HEPA Filter Air Intake port and a fan blowing air out the top.
I've got 6 bins so far. Here is how I have them setup!
They are two 14 Liter bins stacked on top of eachother. The substrate is coco coir, straw, gypsum, and coffee grounds 2-3" thick.
I am also pumping pure oxygen into them through a daisy chain'd hose system. I drilled around 6 FAE holes in the lower bins at substrate surface level and covered them with 3-4 layers of Paper Tape. The idea is that the since O2 is lighter than CO2 that the Carbon Dioxide will flow out the holes.
I leave the oxygen on for about 1 minute or less; and have to refill it for $21 every time.
Here you can see a couple fully colonized Bulk Sub.
Unfortunately two of them got Trich, which I caught before it turned green (mostly). Probably because I used 1 layer of paper tape to seal the two bins together, as I wanted to see if my clean room was really that clean. (Turns out it's not, but at least I tried) I swiftly burned it out of reckless hatred, and scooped it out with a spoon. I then dunked the bulk sub for 6 hours, because it seemed a little dry. I then will flame the contaminated spot again, and spray it with Hydrogen Peroxide. Hopefully this will save it.
I got a bin of Hawaiians to fruit without any dunking but it didn't fruit very much at all and produced extremely large mushrooms. I was able to pull about 1 Oz Dry. Temps 75F
A couple notes.
It sure is taking a while for the bulk subs to start fruiting, as you can see the bins are labeled "Spawned on June 25th"; and It's now July 14th, they are fully colonized but there are still no pins. I think I am going to dunk the bins for a few hours to hopefully stimulate some growth.
Do you think my substrate is too thick? Should I leave the O2 on for longer? Should I have more/larger CO2 out-flow holes?
I've learned so much from you guys over the years. Figured I would update on my progress, and see if you had any more suggestions.
