I have one closet that is about 2'x3.5', close to the area size you have and pull 6 to 8 zips per grow. I use 400 watt hps so heat isnt much of aN ISSUE, and I grow low oder strains so a filter isnt an issue, I don't change out my tote, so nutrients are not an issue. Theres a thousand ways to grow, ur goin about it right. gather info. I pr4efer to do the least amount of work, while spending the least amount of money to get the most bud I can.
