I have a 1000w MH bulb and I have a air cooled ventilator with a 6" fan opening and it shielded with glass on the bottom. What cfm should I use? I heard 50cfm for each 100w is this accurate? Also What size of an area could i use to grow and have good yields on a hydroponic system. Also how far away from the plants could i put the lamp if it was well ventilated?
