I am sittin watchin this last round of plants just crawl along, not fattin up or finishin like I usually like so start thinkin about other current setups and past setups for answers. So I start figurin my watts per sq.ft on a bunch of my different setups and this what i got..
#1 setup is (2)600w over a 3x3 table or 1200w/ 9 sq.ft. = 133 watts per sq.ft. or 19,556 lumens/sq.ft. with this setup I can easily pull 3-3.25lbs from 9-16 plants on the 3x3.This is my all time favorite setup for yield, density, finish time, potency all that good stuff. Dual bulb hood used in a 3x3 Hydrohut tent.
#2 (1) 1000w over a 3x3 table or 1000w/ 9 sq.ft. = 111 watts per sq.ft. or 16,111 lumens per sq.ft. perfect for single bulb single hood setup and or in a tent.
#3 (3) 1000w over (2) 3x6 tables or 3000w / 32 sq.ft. = 83 watts per sq.ft. or 13,594 lumens per sq.ft.. This setup is on movers and does alright but could use another 1k to really kickit into gear, but overall decent.
#4 (1) 1000w over a 4x4 table or 1000w / 16 sq.ft. = 63 watts per sq.ft. or 9063 lumens per sq.ft. To me this setup is right at the edge of what you need to really kick it out like on a 3x3. I really like the 3x3 tables instead of the 4x4 all the way around.
#5 (2) 1000w over (2)3x6 and (2)3x3 or 2000w per 54 sq.ft. = 37 watts per sq.ft. or 5370 lumens per sq.ft.. This sucks bigtime, movers almost make it more painful because of the shadow dancin..lack of cash has dictated this setup but still it sucks.
#6 (3) 1000w over a 11x14 room on movers or 3000w / 154 sq.ft. or 19 watts per sq.ft. or 2825 lumens per sq.ft. this is at a buddy of mines and he is complaining about yield, density, and finish times. this setup is doin just well enough to piss you off, not really crawlin but not cruizin either. I am tryin to get 6-8k in there for he real kickin flower action.
So I was curious what everybody else was doin and experiencin..
The sun is roughly 100w per sq.ft. full tilt so that is my basic minimum benchmark for my indoor satisfaction..
Mo lumens, mo wattage, mo betta..
