To start them you will probably only need about 40w of light. If your planning on vegging them indoor for over 2 weeks you will need to double that ( 4 x 23w) and for over a month I would say you need 6 x 23w... mostly depends on how big they get, pot size and how much space you have

I always use at least 100w of light per 10 plants, so I would use at least 4. I prefer to use 50% red spec and 50% blue spec if using cfl's. I don't know how much growing you've done b4, but don't 4get about hardening off.

I want to get my 20 femed seeds started about late march and clone from them.I can only go out at the first of junebecause of fear of frost.

Do any of you think the 23 watt cfl's will be good or should I go for 46 watt cfl's
