long as it is wide. This configuration allows for
air to be distributed down a central duct-work.
The rectangular shape is naturally process-oriented: permitting the flow-through of substrate

materials and fresh mushrooms. Rectangular
rooms are simply easier to manage.
2) Interior walls The inside skin of a growing room must be built of water/mold resistant
materials. Fiberglass, polycarbonate, acrylic,

glass, galvanized metals can all be used for
interiorizing a growing room. The material of
choice, by most professional cultivators, is
called FRP for Fiberglass Reinforced Plastic.
This high temperature extruded fiberglass material has a smoothed finish, and its pliability
makes installation simple. Furthermore, FRP
will not be degraded by mold fungi, does not
out-gas toxic fumes, and is tolerant to most
cleaning agents. Wood or metal surfaces can be

painted with a mold/rust resistant glazing.
HammeriteTM, Exterior Varathane TM, or marine base enamel paints have been used in the
past with moderate success. Cultivators should
check with local ordinances so that the materi-

als used in their growing rooms fully comply
with food production and building code standards.
For those with limited budgets, the cheapest
material is polyethylene plastic sheeting used
by the greenhouse industry. This material usually survives no more than two or three years

under the conditions used for growing mushrooms. I have attached greenhouse sheeting
using galvanized staples over lengths of thick
plastic tape.
3) Doors As with the laboratory, the grow-

ing rooms should be protected from the
outside by at least two doors. The first door

from the outside leads into an operations
room or hallway where the second door
opens into the growing room. Doors should

be at least 4 ft. x 8 ft. Some farms have two 5
ft. x 10 ft. double-opening bay doors, or a 10
ft. x 10 ft. sliding door. These large doors al-

low the easy filling and emptying of the
growing rooms. A small door is sometimes
inner framed within one of the larger doors

so the growing room environment is not
jeopardized when only personnel need to enter. In any event, the doors should
accommodate small forklifts or similar ma-

chinery which need access to the growing
rooms. The doors should be made of a mate-

rial that does not support the growth of
molds. The bottom of the door is often fitted

with a brush-skirt that discourages insects
from entering. The door jams are usually
gasketed to assure a tight seal when closed.
At the opposite end of the growing room, a
similarly sized exit door should be installed.

This door facilitates the emptying of the
growing room after the cropping cycle has
been completed. To bring aged substrate,
which is often contaminated after the 4th or
5th flush, into the same corridor that leads to

other growing rooms presents a significant
cross-contamination vector.
