Mycelium grows between 10 and 30 C, best at 22-26 C. Above 30 C in the room it stops and dies, and the bag runs 2-4 C warmer than the room. If the bag climbs past 30 C, the folder says to splash water on walls and roof two or three times a day or run an air cooler.
The folder is blunt: during the run the bags need no water, no air and no light. The manual agrees: bags stay closed, no ventilation, no spraying. The mycelium tolerates carbon dioxide up to about 2 per cent, so a closed dark room is fine. TNAU instead asks for 22-25 C with 85-90 per cent humidity in a dark shed.
