Plenty of mushrooms can be grown in a relatively small space. The essentials for mushrooms to survive are:

  • Fresh Air
  • 12 Hours light cycle
  • Relative humidity from 80% upwards
  • The correct temperature

To accomplish this you will at least need a 6 X 3 meter grow house. a Well insulated Wendy House can work perfectly. Cover the inside with a layer of plastic, then a layer of 50mm isotherm and clad that with Newtech board. Paint the inside of your grow house with an anti-fungal paint. It is also advisable to have a drain and concrete slab in your grow house to be able to maintain a clean environment.

When looking at the fresh air requirements for your grow space, most mushrooms need the air to be exchanged 4 times an hour. Work out the cubic meter space of your grow room (L X W X H) and purchase an inline fan powerfull enough to do four air exchanges per hour. Rather push air into the grow space, as this will maintain a positive pressure. Have a filtered exhaust exit on the opposite side of the grow room.

For humidification I prefer using the ultrasonic humidifiers available from Green Thumb Hydro.

For lighting use LED strip lights, these will cost you less in the long term. Have them on a 12 hour timer switch. 

For winter temperature control, have one or two wall mounted eco-heaters on a thermostatic switch to control the exact temperature.

It is advisable to have a separate room for incubation, this room is dark, but also needs fresh air as well as a steady incubation temperature.
