600W Led Grow question

Discussion in 'First Time Marijuana Growers' started by greenzig, Feb 3, 2014.

  1. Could someone with some experience tell me how much cfm are needed for a 3x3 grow tent and what size phresh filter I would need? I have a 600w led grow light so heat really shouldn't be an issue I'm more concerned with proper air exchange
  2. Im running 800wLED with a 4 inch fan and filter... works just fine in my 3x3 and until im into flower, she only runs at 50% full load.
    heat isn't gonna be an issue i do certainly recommend getting a speed regulator for your fan though
