Pace, my buddy JCM came up with a method that is similar to what you describe and it's pretty popular elsewhere on the internet.
Basically, it's a big tub filled with water and lots of air stones on the bottom. Your tray sits on a rack above the water. The lid has
holes drilled out like an SGFC. An aquarium heater at ~85F is used to maintain temps. No fans necessary. People are pulling
down some nice yields with this setup. It's just loud AF.
Hi Asura, Ha - I thought it would be more complicated than that, because I have read so many references to Pans needing evaporation of moisture in the casing in order to initiate pinning / fruiting. I found a write-up that DonShadow did of using the Shadowbox to fruit P. mexicana, which is what I am trying to grow now. He suggested an initial timing of the exhaust fan of 4 minutes every 4 hours to get that evap thing going on... So I have several shallow trays of P. mexicana with fresh casing that are now in the fruiting chamber hopefully on their way to pinning. However the grain spawn was colonized from a multispore inoculation so I dont know if this batch will be robust enough to fruit successfully or not.
On another front, during the past few weeks I have been isolating a very fast growing strain of Pan Bisporus using agar and yesterday I added a few small wedges of promising mycelium-agar to a jar of liquid culture medium. Just a day later, and there is already very significant mycelium growth in the LC. Asura in a week of so when the LC is fully colonized I will use it in your mycobag tech for Pans.
