Shit, I could go on for days about some topics... this early sexing male/female thing has been a very very popular topic around here lately though. I just wanted to explain to you another strategy that I have heard of people doing, but never done myself. Once it gets to a certain level of maturity, put it into 12/12 lighting for a week or something until it shows its sex. Then if its a male... kill it.. if its a female, you can put her back under the veg lights and light cycle to revert her back to veg so you can make her larger, and still know the sex early enough so you're not wasting a ton of time.

I think I'm done now.. I'll finally shut up and let someone else take it from here... I've got plenty of transplanting to do... =(
