what do you guys think of the light all around thing .???
I actually veg under 4-footers, just 2x40w cool white, with great results, until they get too big and have to get moved under my little MH250.
This pic is some Godbud X vegging under flouros, had to swing the light out of the way.

Light all around... I'd say fine for small box grows. But a major pain in the ass to build compared to hanging a 600w HPS from the ceiling
