Hydrohut- I read on that sellers description he was busting on the homebox, which is BS; it's a fabulous product. I'd make the jump to the 4x4x8, you can order it from your local hydro shop, but the 3x3x6.5 is okay for a 400w HPS or flouros if you really want to mess around with them (go for the HPS!!!)

The hut is socked for a proper exhaust and you DO need it no matter what your lights.

Tinfoil is a myth and no choppers are gonna see a few CFLs as something to be concerned wiht, plus that's illegal search. Just for comparison, I run 4 HID lights and a T5 in my ATTIC and don't lose sleep over it. lol

20/6 is only viable on a planet with 26 hour days. Veg under 24 hours of light and 0 hours of darkness or 18 and 6, and flower under 12 light 12 dark.

Do some reading, the link in my siggy is a good place to start.
