Odds are usually 50/50 for male/female from seeds from what I know (unless something is done to change it).

Good idea on the mylar, I was gonna suggest that before I saw your comment.

Be careful about the fan (since you said it was from an old comp) - I used to be a PC technician and I've seen lots of old fans overheat and die or get clogged from too much dust and crap. Keep an eye on it - don't wanna see you have any unecessary problems. You shouldn't need another fan for intake, just an opening to let fresh air in. The exhaust fan will lower the pressure in the growroom and new air will rush in by itself from wherever it can to replace the old.

What kinda light you using??

Venting Umm.. here is my cheap vent job, its at the bottom of my grow space, behind a shelf so that you cant see the light coming from around it and to keep light out but I dont know if its donig to good a job of that, the room is going to be completely dark when flowering, the way my lights are going to be set up.. simply a small computer fan I jacked out of an old one... hope its enough, cause its all I can afford right now..?? Its small but it can move the air... another fan at the top moves air Rating: 5
