Lets see, I've got 1000w total (400w +600w) spread over a 4x9 room (36sq ft) works out to 27.7777 watts per foot, and that's PLENTY of light for some awesome pulls.

My old flowering area was 4x2.75 or so, had just the 400w over it. THIS grow only took up 1/2 of the space

I have heard of "light bleaching" where a grower is using too much light, but I've got no clue what the threshold is for that.


1000w in that little of a cabinet is gonna make for some SERIOUS heat issues BTW
