need help on larger grow room.........

what kinda fan am i gonna need to cool 12 1000 watt hps lights??

One fan will not do it, if you daisy chain all those lights the last 6 will only be getting air that is 80 plus degrees, not very effective...Good luck. JR

lol who said one fan???? ima hang 2 rows of 6 1k lights.... one 10 ince heavy duty fan on each... so 2 fans.... reducers from 10-8 inch and then 8-6 inch i guess.. do they make straight 10-6 inche reducers or no? then ima have a 2k veg room im thinking.... m/h, hps conversions all my lights..... ima run at night hopefully i wont need any fucking a/c.. hows that sound?

Just the fact you said "fan" and not how many "fans", sorry i must be retarded.

I would say running 2 lights in a row is bad news and not very effective. Unless you use water cooling, which kicks ass.

With that much light, I think you will be hard pressed to not to use A/C..Let us know JR

with such a scale room i would go with watercooled lights
