12x12x8 rooms w/6 1ks,yes i tried scrogging.Look im not knocking what you want to do just relaying mine and ALOT of other peoples experience.You can do anything you want but it doesnt make it ideal.I would not have changed if i didnt feel it was neccessary,it cost me money and time but the 1ks didnt work out for me in an 8' room.6/750s were designed solely for this reason,dimming changes spectrum which changes everything.

The
Gavita Pro 750W DE EL lamp for our Pro 6/750 DE FLEX fixture. It is a unique lamp in its class, the first 750W electronic HPS lamp to hit the 1500 micromol level. Many climate rooms do not have the height you need for 1000W lamps, or the crop is too high. A 750W lamp works much more efficient in the 600-825W range than a dimmed 1000W lamp.
Think about it,8' tall room,
gavita hangs down approx. 8'' from ceiling and you need 36-40''between plant and light,so now you have 48'' total grow space and thats with your plants ON the floor,not raised up at all and pots or beds are approx 10'' tall depending,so now you have 38'' for your total plant size,canopy and all.You will end up having to dim your lights which changes the spectrum and all kinds of funky shit will happen,at least in my case it did.Im sure maybe others have figured out ways to get around these limiting factors but i got tired of fucking with it after 3 or 4 rounds,this was when the lights first came out and not alot was known then.BTW those same 1ks i bought at first are in my sons place now KICKING ASS with no problems,the difference?14' ceilings.
