The fruiting stage of growing mushrooms requires cold conditions to aid the process hence the question can mushrooms grow in a room with AC? Growing mushrooms with AC is good for big yields in small spaces. We have been presenting mushroom cultivation as a cash crop and nutritional enhancement for the landless poor. The question of whether you can grow mushrooms in a room with AC or not however is important for people in warm or temperate regions.
Though some species like Oyster mushrooms for example are a high yield, fast growing crop, many mushroom species prefer colder temperatures especially during the fruiting stage; Maitake – a profitable and favorite medicinal mushroom for instance prefers about 50 -65F for fruiting.
A portable A/C unit can work like charm if grow room is located where its difficult for central air to reach but also there are several alternatives that can be considered e.g. some refrigeration components of a common home refrigerator in some cases has been salvaged and used as a cooling chamber hanged from the ceiling in the fruiting area.
But you have to err on the side of caution else you end up sucking the hot air from the rest of the house into your grow area with an AC or cooling unit particularly if it only has an exhaust because you’ll be making negative pressure build up in the room it is in. Whereas it may be cooler than it was before for a while, it’s not as cool and efficient as it could be with a double/dual hose unit or a ducted mini split.
However, it doesn’t have to be loud and big as a typical home AC unit. A portable intake and exhaust unit with with proper layout will make all the difference you need in managing temperature.
Another simple alternative,- the CoolBot is a revolutionary product for anyone who needs access a large-scale refrigeration at a fraction of the price of traditional commercial refrigeration units. Turn any well-sealed and insulated room into a walk-in cooler using an appropriately-sized standard window air conditioner (see insert: image and how it works). Installs in minutes, with no tools or electrical knowledge needed.1
