>50W/Sq'Ft.
1000W = less than 20 square feet (5'x4') of lit floor space.
psteve Reviewed by psteve on . How many plants per 1000 watt lamp? I bought 55 clones for this run, looks as if about 8 of them won't make it leaving me with 45-47 depending how a few bounce back. I feel like that's too few. I'm growing Sour Deisel and Grape Ape - both sativas. I am running 3600 watts, and I'm a bit worried about the # of clones I have. I did some LST'ing...that should fill out my canopy a bit more right? I vegged for about three weeks already, they are around 12 inches tall... and will be left in three gallons for another week Rating: 5
