right

Im gonna be growing in my bedroom closet.. ventilation will be tricky, because the closet is built into the wall, its not a wardrobe, if you know what I mean

It goes roughly 2 feet into the wall, its roughly 3 feet wide and roughly 5.5 feet high, and im going to paint the inside walls white to reflect light.

I can probably get a small fan for circulation and/or ventilation, or if not i'll just leave the closet door and my bedroom window open and have a small fan for circulation so the stems grow strong and to keep the temperature down.

I plan to use one or two 250W MH/HPS lights too.. I also plan on planting 5 of the 10 seeds at first, so hopefully i'll get a better chance of getting females..

The only problem is, I dont know when to switch to 12/12 light cycle, and when to harvest etc etc.. I think B52 is indica, but I only just realised. I prefer plants that are sativa or %50/%50, so when should I harvest it to get less of a indica type high and more of a sativa type high? That's the kinda stuff I need/want to know.....

Does that help? Any advice would be great
