I an usually on the 7th. node, counting from the bottom. It is strain dependand, some take longer. Also males are usually the tall ones, and have a greater inter-nodal spacing.

I was going to run out and get a magnifier tomorrow so i can use this technique on some plants i have going right now... do you think 15x is powerful enough for this? Im pretty sure Ive identified sex with the naked eye on these babies, but I just want to make sure with a magnifier... (these plants are about 5/6 weeks veg).

Here's a few more pics of female preflowers, ~4wks from seed sprouting, showing on the 5th internode.

Great post, I usually can sex all of my plants at around 3 to 4 weeks old from seed also. It is somewhat strain dependent though and some as mentioned do take longer. Preflowers may occur easier in the smaller cups due to rootspace restrictions when compared to the same seedling grown out in a 3 gallon container for instance so usually it's sprout seed, wait for sex, top, then transplant. I have never had to switch to a 12/12 cycle to sex anything either.

Good posts in here!

While I have always heard that males show before females, I have never found this to be true. If I start a group of plants from seed, I always am able to pick out a number of females before the males start showing.

I wish I had a better handle on this. I'd also like to invest in some better optics. I have the cheap plastic Chinese ebay scopes. I'm sure they're fine for a seasoned pro, but that ain't me. Plus I like nice glass lenses. I may look on amazon or ebay for some good glass magnification. I've wondered about the digital scopes that connect to your laptop.

Its really not necessary to have a scope and all that....

Just a pair of normal reading glasses... 3 or 3.5 x will help greatly......

12 bucks maybe...

Try that first.... The glasses come in handy for other stuff too..
