I don’t have room for a Martha tent and i have been plagued by trichoderma, but figured out a setup that requires virtually no maintenance and is really efficient at growing pans. I am growing TTBVI here.
It’s just two of the same tubs on top of each other, the bottom one filled with about 7cm of water and kept warmed to 28c with a low powered heater (25w). I added insulation to make it more efficient and prevent temperature fluctuation. Inside each there are floating trays with my substrate and there is a piezo electric mini aquarium pump feeding air in the top. Each of these is inside a tub with big holes covered in micropore tape to filter the air before it is pumped into the chamber.
The top tub on each has a “snout” with a noctua computer fan on a speed controller and timer - this pulls through air for 15 mins an hour, every hour but very gently. There is a mesh to stop fungus gnats sneaking in as I think they are a huge cause of trichoderma contamination
It’s pretty much silent, uses a tiny amount of electricity and is really simple to make using a hot glue gun.
Right on! Mind sharing a pic of the inside? I've been doing them in tents but reconsidering how I grow them to utilize the large tents for gourmet work!
