MALE OR FEMALE EARLY SEXING

It is possible to
tell the sex of a plant early, and thus move male plants out of
the main growing area sooner by covering a plant is lower branch
for 12 hours a day while it is in a constant light vegetative
state. Use a black paper bag or equivalent to allow for air flow
while keeping out light. Be sure to set up a regular cycle for
these covered branches. If light is allowed to reach them during
the dark period, they may not indicate early at all.
Use a magnifying
glass to look at the early flowers sex type. A male plant will
have a small club (playing card) looking preflower with a small
stem under it. A female flower is usually a single or double
pistil, white and wispy, emerging from an immature calyx.
Some people like
to pre-force plants when they are 8" tall, in order to weed out
the males. When growing outdoors, many growers do not wish to
devote time, space or energy to male plants. Just put the plants
on a 12 hours light cycle for 2 weeks, separate the females from
the males, then revert the light cycle back to 18-24 hours to
continue vegetative growth for the females. Keep in mind, this
is a time consuming process and can put the plants back 2 weeks
in growth. Do not pre-force plants unless you have lots of time.
Just cover one branch per plant with black paper (light tight,
breaths air) 12 hours every day under constant light to force
pre-flowers and differentiate early.
