After washing, the growing room feels fresh.

substrates are particularly susceptible to green
mold growth if humidity is too high directly af-

temperature at the same time each day. Tem-

ter removal of the blocks from the soaking

perature profiling at different elevations is
deemed necessary only in poorly insulated
rooms. With turbulent air circulation, in a
highly insulated environment, temperature

tank. For instance, Shiitake blocks benefit from

stratification is minimized. Manual temperature readings should occur at the same time
every day. If constant-duty chart recorders or
computer sensing systems are in place, they
should be reviewed daily and compared. Ambience of temperature within 3-5° F. is preferred.
7) Charting relative humidity. Relative humidity requirements change with each species,
each day. Charting humidity can be a valuable
tool in training the growing room manager to
delicately balance the environment in favor of
mushroom formation & development, but limiting the growth of molds. Wood-based

Oyster mushrooms require sustained 90% +

8) Dispose of contamination once a day.

Once you have handled contamination,
consider yourself contaminated. If removing

Trichoderma (green mold) contaminated
blocks of Shiitake, that person is then unworthy of any activity where susceptible substrates
would be encountered. For many growers, this
mandates that contaminated cultures be disposed at the end of the day. If contamination
must be dealt with early in the work day, a per-

son non-essential to the production stream
should be the designated disposer of contaminated cultures.
