Wow! Great info there bro, THANKS!!! But I got the hortilux 400hps for 2 reasons; 1. TEMPS..(live in hot azz S.E. united states..summer iz coming!) and 2. Although I know more light/lumens is better with a 600hps, I was kinda following inbudwetrust grow journal with a 400hps and will use some dutch master liquid light & penetrator jus because i'm using a 400hps .....chk it out;

Just was going to implement hiz idea with AUTOS....whatta ya think?
But it may not be a bad idea to use a 600hps with the same set-up though! (may have to buy a potable A/C or window mount A/C) What kind of ballast you using with that kind of bulb? and are those bulbs better than Hortilux??
Going to be growing in a 16sf area,,(Homebox XL, 56"x 56"x78.75") in 3 gal grow bags with FF ocean forest with dolimite lime & 30% perlite mixed in. a windtunnel 6 exhaust fan, (409 cfm) with a odor sok carbon filter. 16" oscallating fan and Co2 boost bucket
I'm also gonna have four 2' HO T5 floro's in each corner of tent for an additional 8000 lumens of blue lighting.. !My nutes will be FF grow big, tiger bloom and big bloom as well as FF open sesame, beastie bloomz, and cha-ching...Also, some AN voodoo juice, tarantula, and phranaha. Some cal-mag, black strap molasses, superthrive, bio bizz bloom and clearex
They will be started/germated in jiffy pellets and then placed in 18oz party cups, with FF happy frog soil under four 4' HO T5's, (20,000 lumens) @ 20/4 till sexing...
Remember I will be growing "vertical",(the light hanging 24" from the ground) with a step set-up, (8 plants in a circle on the floor 24" away from the light and 8 plants on a 18" step, 12" behind the ones on the floor, rotating when ness.) so you get more useable light than if you were using a hood/reflector...BUT more light is never a bad thing!
