i saw mention of 4 lbs. per 1k light somewhere in there... but i don't know if its accurate.
as far as i can tell he was using 28 lights for that 44 lb harvest; 20 1k's and 8 600's. Plus its a sealed room with co2, chillers for the rez. etc. 30 thousand watts pretty easily. Way out of my league.
I'll have to re-think hydro setups after this second (ebb 'n flow) hydro harvest. Still want to see if there's a decent improvement over the last run.
Was looking at some Attitude seeds for 700 bucks per 10 fem. beans. Had my heart set on them (G13xHaze). Then i started to read smoke reports on the strain and found it completely standard fare (other than the beautiful silver / red appearance of the buds). So now i'm just popping the beans that i created. Mr. Nice crossed with 5 different strains: more Mr. Nice, White Widow, Durban Poison, White Russian and an auto-White Russian.
Still looking for a heavy yielder ... but it has to be from seed. And everytime i check out the seed recommended by someone it's out-of-stock

ah well.
