The Mushroom Growing Room/63

Structure
The basic structure of a mushroom house is made of wood or concrete block with a cement
floor. Because water collects on the floor during the cropping cycle, provisions should be made for
drainage. A wood floor can be covered with a heavy guage plastic. Interior walls, ceilings and exposed wood surfaces should be treated with a marine enamel or epoxy-plastic based paint. A white
color enhances lighting and exposes any contaminating molds.
The most important feature of a growing room is the ability to maintain a constant temperature.
In this respect, insulation is critical. The walls should be insulated with R = 11 or R = 19 and the ceil-

ing with R=30 insulating materials. Fiberglass or styrofoam work well but should be protected
from the high humidities of the growing room to prevent water from saturating them. For this purpose, a 2-4 mil. plastic vapor barrier is placed between the insulation and the interior wall.
An airtight room is an essential feature of the mushroom growing environment, preventing insects and spores from entering as well as giving the cultivator full control over the fresh air supply.
During the construction or modification of the room, all cracks, seams and joints should be carefully
sealed.

Many growers modify existing rooms in their own homes or basements. The main consideration for this approach is to protect the house structure (normally wood) from water damage and to
make the growing chamber airtight. This is accomplished by plastic sheets stapled or taped to the
walls, ceiling and floor, with the seams and adjoining pieces well sealed. If the room is adjacent to an
exterior house wall where a wide temperature fluctuation occurs, condensation may form between
the plastic and the wall. Within these larger structures, a plastic tent or envelope room can be con-
