With this method, you can determine the sex about 3 weeks before you see the first preflowers.

no, those ARE the preflowers. this is how you do it. i've been doing this for 15 years. preflowers are flowers that appear prior to flowering.
they appear at the 8th to 12th nodes. often the 8th node only has them on one side. then the 9th, 10th and 11th nodes usually have nice fully developed flowers. the 12th may or may not have them. you won't see any after the 12th.
you can pollinate these "preflowers", if you happen to have any pollen around. i did it last year.

Really? Tell us if not pre-flowers what exactly we are looking at? Pre-pre-flowers?
When I learned this method those tiny little "micro-flowers" were called pre-flowers and then we just called it sexing the plants, not micro-sexing.

I posted that I stood corrected. Why don't you read before spouting off your mouth. You have 4 posts and come on here with an attitude like that. I forsee you getting banned very shortly. Instead of being such a smart ass, why don't you contribute something from your infinite wisdom?

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. Check out my journal here:

would this work on plants that have been topped as well?
Flowering my plants now and all of them seem to have the longer pre-flowers its only been about a week some look like hairs but still to early would i DEFINITLY be able to tell a male from a female within the next week or so just curious because if i have any males i would like to put that Hydro set up to better use.
