I would be using it on the low setting. Think that will do the trick? Also, I am trying to figure out how to use PC Fans in the flower box also for extra ventilation. I have 3 120mm 90CFM PC fans that I was going to hook up to a fan controller and use also for exhaust. I just need to figure out how to carbon filter pc fans for this. Some say they are not strong enough for filters. What if I had one fan pulling air from inside box then the filter then another fan exhausting out of box?

Or maybe two of these fans side by side running to a rectangular filter tube?
UpInVapor Reviewed by UpInVapor on . Stanley Blower for Cool Tube? Does anyone know if you can use the Stanley Blower mod for cooling a 6" cool tube for a 400W HPS? I plan to hook the 6" duct to the intake on the blower and let it pull cool air through the tube over the light and out the box. The blower would be outside the box pulling the air and blowing it out into an adjacent space(Spare Bedroom). I am thinking about hooking up a DIY Carbon Filter to the exhaust end of the blower so it pulls air over lamp, through duct, out blower and through filter into Rating: 5
