I have 32 plants under 2 600watt bulbs.....I have gotten over a pound a light, which you should get, using CO2. Basically it works out to an oz a plant. 16 plants per 4x4 with that light.works for me except this grow ive been getting high humidity lvls due to some bullshit I have to fix.
Also find a strain that has a high yield, another important factor in yield amounts
thanks for that info... sounds like a nice setup.. you think if you had a 1k it would do the same job ?? and im guessing your running indica strains to be running all those plants in one spot ? and is that a soil or hydroponic set up ??
