Micro Sexing before taking clones

[Earl]

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.

[tahoe58]

thanks kp....thats what I thought...and ...hmmmm..interesting...

your first boy pic is a girl

 

[thenextlevel]

nice. ill have to check this out

 

[VictorVIcious]

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

Thisn is a boy.

Here he is a couple of days later.

A young lady.

is this method legit? it would be great to be able to sex a plant this easily.

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.

Now THIS is what this forum is all about - real information. Thanks Earl.

I must have missed something, what was the twist tie for?

 

[n8wi]

yeah, HAHA, I don't remember you using the Shepard hook at all!!
I am not laughing at you, but rather, laughing because I am stoned

 

[potpimp]

The shepherds hook it used to scratch the male plants little balls; you know they itch and there is nobody to scratch them. ...then you kill the male plants - but only after you scratch their little balls.

Thanks for the tip potpimp!

My babies just reached their 8th node over the weekend. I *think* I have all girls but I'm not sure. I looked at the node with a magnifying glass and I think they are all girls but I'm not absolutely sure. I want to take some clones ASAP! Can you check these out and tell me if they are girls or not? Thanks in advance!

hard to tell give em a day or twoo

 

[Torturedzen]

This 'micro sexing' technique is nothing new. Hasn't any one ever heard of preflowers?

Hey Earl, Im a long time follower, yet 1st time poster on one of your threads. I am so hoping this works for me. My 1 plant is now 19 days old from popping out of the ground. I am at 8.5 inches tall, and the 8th node is now forming on top. I know you said it is easier to tell when the plant in on its 10 node, but when does the earliest signs start to show? I guess I will check everyday until I see something that looks M or F. Either way, I have 3 more 1 week behind her!

 

[dmoose]

Thanks for making this thread! Turns out the oldest plant is male. I have been experimenting, and torturing him. I did LST and loved how it increased the Bud Sites! I may try topping it next to see how that effects it. I want to have the tecniques down before I perform them on the girls! I have learned that from VV practicing his cloning tecniques on the Male plants. It was nice meeting him in Lansing on the 5th. I just confirmed the other 3 are Female! So I am finally working towards a Harvest! Heres a pic of my DIY Portable 2x2x4 Veg Box.
