if you keep reading or do a search on sexing plant you will find 1,000 posts with your answer...not trying to be rude...i am new to this forum but have been a member at others for years now...just putting this up before a long time member rips you a new one for not looking for yourself before asking...good luck
yeah ... but thats a really good question too. everyone wants to know how to sex their plant ... thats why people keep asking : ) . youll probably just want to be watching for male or female preflowers though if your early in op. pics?
