How do i figure out how long to run my intake fans and carbon scrubber. When do i bring air in and when do i suck it out and how long is each cycle? My grow box is 4ft x 4ft x 7ft i am going to run 9 plants with a 1000 watt HPS. With a complete co2 setup. I was told on another post to run exhaust the box 6 times a day for 30min each cycle, and then co2 would be added after each exhaust. but when do i bring air in?
