Four ounces is pretty easy assuming you haven't stuffed too many plants under an adequate light.
im trying to figure out how many that is for a given space. say, using containers, on tables, 8' x 2' tables. each table has (3) 1000w HPS over it. would 20 per table be too much, if you had them in say, 1 - 2gal containers? what if you had less plants, and slightly bigger containers - would you run less lights, or run all the ones you had, even though you were running at 35 - 45% less capacity in # of containers than normal. that make sense?
