Flowering
Earlier in the book (Chapter 3), we described how marijuana
determines when it should flower. It senses the onset of "Fall" by
measuring the number of hours of uninterrupted darkness. When
the plant senses a period of uninterrupted darkness long enough
each evening, it triggers into flowering.
The period of darkness required varies by variety. Equatorial
varieties need a longer period of darkness than indica or Southern
African varieties because the equatorial growing season is longer
and equatorial plants have shorter days. Equatorial sativas flower
when the dark cycle increases to 12 hours or more. Most indicas
flower at between 12 to 16 hours of light, 8 to 12 hours of uninter-
rupted darkness.
Male marijuana plants flower before the females and are only
partially light-sensitive. In some varieties the males seem to flower
after a few months of growth, regardless of lighting conditions.
Since female marijuana flowering is regulated by light, a
cultivator growing under lights can put the garden into flowering
with the flick of the timer. Once the plants start to bloom, they will
grow another foot or two in height. The plants should be set into
flowering before they get too tall.
G?owers use several lighting regimens to start the plants
flowering. Growers using continuous light or another long day cycle
can cut the light back to flowering cycle with no intermediate steps.
The plants do not suffer from shock or exhibit unusual growth.
Some growers do introduce the cycle more gently, cutting the light
back to flowering cycle over several weeks.
After 4 to 5 weeks of heavy flowering, some growers set the
light back another hour to simulate the shortening season. Growers
cut the light back another hour after another month. This may be
especially helpful in finishing some tropical varieties, which do not
reach maturity in their native lands until the middle of the short day
season (there is no winter in the tropics).
