I've looked everywhere for info on floro tubes...can't seem to find what I need.

I have 2 4' hoods with 2 40w floro tubes in each. I've had success with my first half-assed grow attempt before researching anything vital and have 2 females. (YAY!)

I'm looking to build a growbox about 4.5' long by 4' high. I don't know how wide I can make it before I start losing reflective light from the sides.

...and, do I need to swich out my tubes for something else for budding?
