Identifying a
true preflower is way to tell sex before 12/12. That way
you can take clones from the known females without
wasting the time and space on males.
Note:
(Kifit) "do not try to sex a seedling based on the
very first preflower you see with a 25x times
microscope.....wait and make sure. The time between
using a 25x to spot the very first preflower sex and the
plant dropping pollen is at least 10+ days away and so
it's safe."
"It's best to cull a male only after
you are 101% sure - when you see 2 or 3 (or more)
immature male flowers bunched together on the internodes
or the top growing tip - this is a male, for sure,
females preflowers have white " spears " that appear in
a vee. ..but "every now and then a sexually
indistinguishable flower appears" (Ed Rosenthal)
After a few weeks in veg, plants will begin to
show their sex. Usually the males show first. The male
preflower is a miniscule ball. It appears that there is
a small piece of foliage that covers the ball and
protrudes outward when the male preflowers first appear.
The following pics show MALE preflowers the
FIRST day they show their future pollen distribution
centers.
Many times preflowers will appear at
the fourth or fifth node, whereas the plant is on the
7th or 8th node. These preflowers usually don't develop
into full flowers, but are only an indicator of the
plants sex.
Female on
left, male on right. Im only certain about the sex cause
I watched them several more days. 25X magnification.
