no, not how early do you HAVE sex, but how early do you sex your plants?

there are several methods of sexing, which do you use?

i usually wait for my seedlings to get about a month old (at least 7 nodes) and throw them on 12/12 for a few days. generally about 90% will show their sex in 3-4 days. then when im positive what ive got i put them back on 24 hour light and reveg them until im ready to flower.

BE CAREFUL though doing that with older plants. while some strains go back to veg rather easely, ive had some (such as that OG X Martian) just go into a "holding pattern" and continue, ever so slowly to produce female pistles . not really buds mind you but poppin pistles here and there. when i put my martian on reveg ( when i got it, my bro had already started 12/12 on it ( he said it was on 4 days, but i think more like a week myself) when i put my matian pla nt on reveg 24 hour with my other plants, it did this, and when i went to 12/12 it literally exploded with flowers and pistles overnight. it was like it had all those budding hormones built up ( just like a horny school girl) and went nuts when it got what it needed...LOL.....she got wet and sticky real fast!


that put me in mind of this time i had a new grower call me up. i got on the phone and he said "man, you GOT to come check my plant out!....the buds are so sticky and wet they are literally dripping resin, and they smell great!!!"....i tought to myself ....hmmmmm...SOMETHING DOESNT SOUND RIGHT. i popped over to his place ad he took me out to his flowering room. i looked at his buds, and the top kola WASNT "DRIPPING WITH RESIN" IT WAS DRIPPING ALRIGHT , BECAUSE IT WAS LITERALLY ROTTEN AND SLIMEY, like a bunch of celery thats been forgotten in the friges crisper drawer for a month or two. the stench was gut wrenching. smelled like a mixture of blue cheese, dirty feet ,rotting skunk and sweaty rank dirty unwashed vaggy. i damn near puked on the spot. i told him how screwed up his sit was and he literally cried when he pulled those girls up and trashed them.
