I bought a used Sun Hut LG grow tent that is 54" Deep X 35 1/2" Wide X 84" Tall, I was thinking of going with a one 1000' Watt MH/HPS, can you run two 1000' Watt lights or maybe two 600' Watt lights, So how do you figure out how big of fan do you need, new to grow tents, so one exhaust fan connected directly to the light correct, do you need a separate fan to exhaust the tent, or maybe one fan to draw fresh air in, or is the one fan on the light enough to cause positive air flow, don't care about the smell more concerned with heat temps, So any advice would be appreciated,
