PARAMETERS FOR OPTIMAL GROWTH
(adhere to these as much as you feel comfortable with. Satisfactory results can be had by keeping the jars on a closet shelf from start to finish. But trying to follow these guide-lines will certainly lead to better crop yields.

STAGE DURATION HUMIDITY TEMP CO2 LIGHT
SPAWN RUN:
(1st stage
of growth) 10-14 days 90% Substrate
84-86 ° F
(Thermal death at
106 ° F) 5000-10000 ppm
Fresh Air Exchanges: 0 per hour. Incubation in total darkness.
PRIMORDIA FORMATION:
( pinhead formation ) 6-10 days 90+% Air
74-78 ° F. less than 5000 ppm
Fresh Air Exchanges: 1-3 per hour.
(but remember this air MUST
be free of contaminants such as dust.) Diffuse natural or exposure for 12-16 hours/day of grow-lux type fluorescent high in blue spectra at the 480 nanometer wavelength.
(Regular fluorescents can work fine, but try to let jars get some natural sunlight whenever possible)
CROPPING: Flushing Pattern:
Every 5-8 days. 85-92% Air
74-78 ° F. less than 5000 ppm.
Fresh Air Exchanges: 1-3 per hour. Indirect natural or same as above. (hint: use same as above.)
HARVEST STAGE: When the cap becomes convex and soon after the partial veil ruptures.
