GROWTH PARAMETERS
exponential expansion of mycelial mass. The
simplest method for most cultivators to follow
is similar to the classic spawn expansion schedule employed by most laboratories. The first
stage is to grow the mycelium on nutrified agar
media in petri dishes. The next is transferring
pure cultures onto sterilized grain, typically in
jars (quart, half gallons, gallons).At75° F. (24°
C.), two to three weeks pass before colonization is complete. Each of these "Grain
Masters" can inoculate 10 gallon jars each con-

spawn can readily inoculate 10 5 lb. bags of

hardwood sawdust (wet weight, 65-70% moisture). The resulting sawdust spawn is the last
step before inoculating a substrate capable of
supporting fruitbodies.
