Sun Hut Question

I just got a 4x4 Sun Hut tent. I want to grow as many plants as possible, but I don't know how large of a pot each will need. I'm using a 1000w but that doesnt really matter. I can't afford an aero jet yet so I will be using individual pots and a bum drip system. My question is how many pots can I fit inside my 4x4 (48in square) without the plants going retarded from going rootbound?? I want to veg for 30 days and flower for approx. 50 days. Assume that I don't need to reserve room for any equipment. Thanks +REP

with 1kw in the 4x4 i wasnt able to keep it within limits without using an ac unit in conjunction blowing into the tent, but if you can vent in some ac and vent out the 1kw via air cooling. then you can slam the room with as many plants as ya can fit. im going scrog next run in there, but i only have 400w in the 4x4. to flower i say 4x4 should have 600 atleast.
