You basically want to push cool air over the bulb and pull it out the room.One strong fan will do the job or u can use 2 duct booster fans works perfect for me..

u might be overwatering and giving to many nutes.....if ur flooding four times a day with nutes that is way to much...try cuttin it back a little bit

well I would have to say I drought its your light being to hot from 2 feet away unless you have no ventilation in your space and its 90+F in there.. my box stays at 82F and my 400hps is 4-6 inches from my tops, with no cooltube, just a pc fan blowing on it...
