Did you know
that you can determine the sex
of your plant before you switch the lights to 12/12?

Well you can.

We call this the pre sex indicator and it appears on the 8th node.

These are the tools you need. The shepards crook is just a bread tie with the plastic burned from the end.


This is the size of the plants that will be sexed.
It is easier to do after the plant has reached the 10th node,
and then you can easily see the indicator on the 8th node.


This is the area we will inspect.


A girl


A male


Another male


Be sure and take your clones from obvious females
with an idicator on the 8th node.

The male indicator is harder to see
because their balls are smaller
and they don't have the pistils sticking out
which are more obvious.

Check this phenomenon out
and you will learn to spot the pre-sex indicator every time.

very nice.. great job

So if all the plants I am seeing in the first pic are the same approximate age, about the time they start to shed the lower leaves?? That makes sense. now if I could see.....lol. VV

Absolutely works. I haven't switched to 12/12 yet (my plants are only 15-16" tall and 60 days old), and I have 2 confirmed females, so far, just by closely examining the upper nodes. Upon further researching the matter I found out numerous articles explaining how a lot of strains of MJ will show sex early, between 12" and 14" tall, but it's kind of a luck of the draw because some strains will only show sex during 12/12.
