A bud is a
cluster of single female flowers.
As you can see
in the pic, this cola is composed of several sub-units
that are will fill out before reaching maturity. In this
phase, the plant has finished the stretching phase and
is developing bud sites.
Depending on the
strain, bud development may start in the middle of its
single sub-unit is itself a cluster of single female
flowers. New Flowers are formed throughout the flowering
period. You can see new flower production on top of each
In this pic, you can see (above the
yellow lines) where the single sub-units develop new
single flowers. You can recognize them because the new
pistils in formation have tiny stigmas.
a single flower!
This pic is a pre-flower but is
alright for our purposes. It explains how a single
female flower formation occurs.
flower is called a pistil and the two hairs coming out
of it are called stigmas. Male pollen reaches the
stigmas and make their way to the female egg cell which
is located inside the pistil. This pollination process
will produce the seed. Growers tend to prefer seed-less
produced on female flowers and on the leaves near them.
It is produced by a particular structure called a
In this pic you can see on
the leaf that resin is produced in some kind of ball
over a thin neck. if you have a magnifying glass, you
can look in the ball and see color changes (from
transparent to white to gold/brown) and determine when
resin production and THC % has peaked. Rough handling of
buds will break the trichomes off.
Let's see now how a pistil evolves during
the flowering period. Above the yellow line you can see
a young pistil. It is thin and has white hairs.
Here is a pic of an older pistil. The body has
enlarged. The stigmas are still looking for some pollen.
The small leaf under the pistil is called a stipule
(Stipules are more evident with pre-flowers.)
probably two or three days later, as you can see hairs
are becoming (starting from the top) brown/red. Probably
at this stage it can still receive male pollen.
pic I've underlined three pistils that are as mature as
the one in the previous pic (more or less). Other
stigmas have dried up, probably due to rain and wind. In
these conditions some stigmas lose their vitality and
start to dry and to become brown/red. This is not a sign
of ripening, just a normal event
left of this pic, you can see two pistils fully mature.
The stigmas are totally colored and dried. The body of
the pistil is now fat and is beginning to lose its
turgidity. On the right you can see a cluster with
pistils in various stages.
after a couple of days. It has lost its turgidity and
probably is not receptive to pollen. it is dying. When
all 70/80 % of all the pistils of a bud are at this
stage, resin production has slowed if not stopped.
The maturation of the pistils in a bud is
not synchronized but gradual. As you can see in this
pic, you have lots of pistils at different stages of
development. See the dimension of the bodies. At
harvest, you will probably see lots of brown hairs, but
also some white at the top of each single sub-unit where
the new formed pistils are.
stigmas are dried and pistil is dying , the hairs will
easily break and fall down.
