1700w

how many plants can u put under 1700w of hps

it totally depends on a number of factors, but i would say 50-60 like say on a 4x8 flood and drain would be a good option, and you could pull about 2.5 pounds pretty easy i would say, i used to have that table with 64 plants on it and would yield around 3 p's maybe a little less but i was using 2 1000 hps

its in soil

4-600 watts per sq metre of plant tops for a good harvest
