i have a 8x24" vent 6 inches from the bottom with an ultra allergen filter across the back of it. Thats why the vent is so big, since the air will come in more slowly because of the filter. On the ceiling of the cab is a 7 1/2" hole with a 7" fan that I took apart for the motor and blades. It has a high and low setting like most household fans. I used it assembled on my last grow as a vent fan and it seemed to work just fine. Then again I was using 2 70w hps lamps in a different cab then too.
hatecable Reviewed by hatecable on . Air Cooled 250w hps? Yo guys. Ive been reading myself sick on this site and am finally going to post a question. So if the info is out there, i missed it and am sorry for the repeat. Im setting up my first hydro W/F single plant grow in a 2'x3'x6' cabinet. Ive been really trying to get my lighting dialed in before I make the purchase. I was looking at using a 250w hps with one of those solarmax bulbs if it can be found... though i havent found one for 250w yet. Alternatively, I would probably use 8 27w Rating: 5
