i looked at discount hydro and they have a valueline 4" 170 something cfm inline fan for $100. then you can just use a 4" to 6" adapter. thats what im using right now. but i think if you were to use more than one light on the same exhaust system, you would have to go with a 6" fan. then i think i would use the 4" for odor control.

I would like to keep the price as low as possible but the idea of getting a system that would be able to use an hps or mh bulb is pretty Rating: 5
