I use a Philips son agro 430hps.(Google it). its good for veg & flower has 30% more blue spect... I'll throw up some light charts. I use that light in a 22" x 20" x 5ft.. space..just a fan and no venting....

"Those were 2 4ft. kahuna.. I got an oz(dry) per approx but they weren't done right as I started with t's and switched to HID at 4 weeks..
now I started 6 autos and 3 were males, but 6 would have worked well there at approx 15 - 20 " tall....they're supposed to give 28 - 40 g each..we'll see...
