As far as your tent goes. I bought a Topogrow 32x32x63 tent kit that came with a 4" carbon filter, exhaust fan, ducting, and a “300” watt led (which I replaced with 2 600w Mars Hydro leds). I grew, 3 plants in a Scrog and found that 3 was a little too cramped for the space. I did manage almost 1/2 lb of dried bud from that space though. I just finished my first grow and expect a bigger harvest from my next one but I’m super stoked about my results the first time out and the great people on this forum helped me every step.
