| Cannabis
plants are either male or female. The male plants produce pollen which
pollinates the flowers of the female plant, which once pollenized,
produce seeds. If the female plant isn't pollenized (if there are no
male plants nearby producing pollen), the flower/buds continue to
develop and produce THC. Female plants which are not pollenized are
referred to as sensemilla (without seeds).

in-depth information on the gender of marijuana plants
Female
Pistils - notice the sac and the feathery frond-like structure. Usually
after five days to two weeks you will begin to see a pair of tubular
nodes. Hopefully they will have white hairs protruding from them as
this denotes a female plant. These little hairs are known as pistils
and they are the first sign your plant is flowering.
Female Cannabis – The female cannabis plant, unlike the male,
is grown to produce marijuana. Premium marijuana is produced in
seedless form by eliminating all pollen sources from the growing
environment. Seed production reduces the value of marijuana
dramatically by lowering the yield and potency of the flowers.
The female flowers appear as two long white, yellow, or pink pistils
protruding from the fold of a very thin membranous calyx. The calyx is
covered with resin exuding glandular trichomes (hairs). Pistillate
flowers are borne in pairs at the nodes one on each side of the petiole
behind the stipule of bracts which conceal the flowers. The females are
recognized by the enlargement of a symmetrical tubular calyx (floral
sheath). They are easier to recognize at a young age than male
primordia. The first female calyxes tend to lack paired pistils
(pollen-catching appendages) though initial male flowers often mature
and shed viable pollen. In some individuals, especially hybrids, small
non-flowering limbs will form at the nodes and are often confused with
male primordia. The female plants tend to be shorter and have more
branches than the male.

SATIVA/INDICA
|
Because
there is large selection of strains in the internet, this can sometimes
get overwhelming when trying to decide which one to order. Choosing is
not as difficult as you may think. There are really only two sides of
the marijuana family we are talking about here. Indicas and Sativas.
|
Sativas
are just about the opposite of indicas. They are tall, thin plants,
with much narrower leaves and grow a lighter green in color. They grow
very quickly and can reach heights of 20 feet in a single season. They
originally come from Colombia, Mexico, Thailand and Southeast Asia.
Once flowering has begun, they can take anywhere from 10 to 16 weeks to
fully mature. Flavors range from earthy to sweet and fruity. The stone
of a Sativa is cerebral, up and energetic.
|
Indicas
originally come from the hash producing countries of the world like
Afghanistan, Morocco, and Tibet. They are short dense plants, with
broad leaves and often grow a darker green. After flowering starts they
will be mature in 6 to 8 weeks. The buds will be thick and dense, with
flavors and aromas ranging from pungent skunk to sweet and fruity. The
smoke from an Indica is generally a body type stone, relaxing and laid
back.
|
Combining
different indicas, different sativas or a combination thereof creates
hybrids. The resulting hybrid strains will grow, mature and smoke in
relationship to the indica/sativa percentages they end up containing.
|
FLOWERING
TIMES
|
Flowering
times are an indication of how long it will take the plant to mature
indoor after flowering has been induced by changing the lights to 12
hours of darkness. This will be affected by the environment to some
degree, but is pretty much fixed in the plant. Indicas are faster
flowering than sativas and hybrids are in relationship to the
percentage of each they contain.
Equally important in the process is vegetation time, or how long you
grow them before flowering is induced. Sativas grow very quickly and if
we wait too long to flower them they will outgrow the limits of the
space and will not fill out. On the other hand, if an indica is not
grown for long enough, the yield can be greatly reduced. In the
scheduling of the process they can often both end up taking about the
same amount of time to grow and mature.
