An inexpensive hygrometer for

measuring relative humidity.
the growing room with a lighting system that provides even illumination to all areas and levels.
Flourescent light fixtures are the most practical and give the broadest coverage. These fixtures
should be evenly spaced and mounted vertically on the side walls of the room or horizontally on the
ceiling above the center isle. An alternative is to mount the lights on the underside of each tier of
shelf or tray, at least 18 inches above the cropping surface. To eliminate the heat and consequent
drying action caused by the fixture ballasts, these can be removed and placed outside the room.

The best type of light tube is one which most closely resembles natural outdoor light: i.e. one
that has at least 1 40 microwatts per 1 0 nanometer per lumen of blue spectra (440-495 nm). In
contrast, warm-white fluorescent light has only 40-50 microwatts/nm/lum. and cool-white has
1 00-1 1 0 microwatts/nm/lum. Commercial lights meeting the photo-requirements of species
mentioned in this book are the "Daylite 65" kind manufactured by the Durotest Corporation and
having a "color temperature" of 6500 K and the "Vita-Lite" fluorescent at 5500 K. These color

temperatures provide the proper amount of blue light for promoting primordia formation in
Pleurotus ostreatus, Psilocybe cubensis and in other photosensitive species.

Environmental Monitoring Equipment
Few organisms are as sensitive to fluctuations in the environment as mushrooms. A matter of a
few degrees in temperature or humidity can dramatically influence the progression of fruiting and affect overall yields. To adequately monitor the growing environment, quality equipment is essential
for accurate readings. This equipment should include maximum-minimum thermometers to gauge
temperature fluctuations and a hygrometer or a sling psychrometer for measuring humidity. Hygrometers should be periodically calibrated with a sling psychrometer to insure accuracy. Thermometers also should be checked as there are occasional irregularities. Other more advanced, expensive

but not absolutely essential equipment helpful to mushroom growers include: CO2 detectors;
moisture meters; anemometers; and light measuring devices.
