CFL 42W/150W flouro OK to veg?

[Nochowderforyou]

I guess I'll just bite the bullet and get a MH and a HPS but how powerful? Want to veg to 8"-10" inches for SCROG grow 1 plant growing a 2'x2' screen using soil on this one:-(

Whoa holy shit I'm blind, I see your space now duh!

8-10 inches high is not even a ft. That is quite a small space. I suggest using nothing but CFL's. Low heat factor, hps produces a lot of heat and you NEED a fan to keep it cool. For your space, you have the 42W CFL already, I would get a 25W CFL, a total of 67W CFL's for vegging. But when flowering hits, you will probably want to add another 25-35 watts of floros/CFL's. Having a total of 92-102W for flowering.

Keeping your plants that short will be a challenge, hope I helped, good luck.
