Do not get a 1000 watt for that box or you will have problems with heat. A 600 will do fine. Get a 6 inch vortex and yes they make lots of noise. Get or make a duct muffler, mount fan in box, ballast outside. The bulb makes noise as well.
I understand this, I am getting an aircooled hood therefore I can put the light closer, right?

Is it possible to sleep in the same room with all of the noise? Any recommendations on a great HPS bulb?
DurbanStone Reviewed by DurbanStone on . Will this exhaust 1000 watt HPS? Well, this site seems to be overrun with underage smokers rather than of age growers, and there doesn't seem to be enough traffic in the grow forums, so I'm attempting at asking my questions seperatly. Will this exhaust a 1000watt HPS aircooled hood from a 4x4 hydrohut? Vortex 4 Fan Carbon Filter Combo - Vortex Power Fans Rating: 5
