Hi All,
My partner and i have a small scale(24m²) fruiting chamber in which we produce gourmet(only) mushrooms. Growing mushrooms is quite an easy procedure, BUT.... the capital input is high, it is super time consuming and your are fighting against contamination which is EVERYWHERE!!! I have no doubt that the CO2 a bag can produce is viable, but i don't believe this is the best method of CO2 application. also, it seems you would need to turn the air exchange off(exhaust etc) to achieve the adequate PPM . I wonder if you would be able to build a "box/Tote"' with the bags inside that feeds directly into the tent with the cool CO2 rich air drawn in to offset the volume pushed out of the exhaust.
