Plant Count

Long time reader, first time posting.

Question, how many plants in a 4x4 area that received 4 weeks of veg. In soil, under 600hps. Also what pot size would you use.

I have been growing for some time now, 4 yrs. I have always grown "Trees" that received 8 weeks of veg, with a 600hps on top and a 400hps in the middle. Give or take depending on strain I get around a pound every 8 weeks. All in 7gal pots.

Well I just upgraded the whole setup with a 4x8 tent with 1800w and I want to veg for 4 weeks then flower, attempting to harvest every month. So I'm looking for some growers that are getting around a pound in a 4x4 with a 600hps.

I know some of you might ask why don't I just double what I'm doing. Well I have paying money to watch them get taller and with this setup I can save 200w about 15 per month.
