More heat is false dude is running 800w and most energy on all lights goes to heat not light and more so on cfl's than hps. You are believing old myths.
And the buds he gets are not equal to 800w buds are they?
I'm still not sure about bud size yet because I am still seeing clear trichs at the end of week 14. don't buds swell in the last two weeks?
also, I've got about 30 6 or 8 inch branches with bud the entire length and pretty thick... the rest of the branch 6 more inches or so that isn't seeing light has no bud (i've been a smoker for years.. I know a thick bud... I'm just curious HOW much thicker?)
the new cab is 2 1/2 feet by 1 1/2 feet by 4 feet and I'm not sure which way to sit the darn thing. I could have 4 feet of height leaving 2 1/2 feet width... put a single 600 watt in there with slight scrogging or putting it sideways and using cool tubes and 2 400 watters in the corners with cool tubes and scrogging at 12 inches leaving 12 inches left between scrog and lights... (six inches for the light itself)
or use my first cab that is 6 feet high by 1 1/2 by 2 1/2. (right now using it for flower on bottom half, seen in pics, and seedlings up top...)
so basically two different cabs, the bigger slender one is being used, the short fatter one is still pending... all because I don't know which one is better for the hps setup. either one 600 watt in the tall cab or 2 400 watt in the shorter wider cab.
