Removing the heat

hello can anyone help with my question? please bare with me my floweringroom is 11 x 11 with 1000 w hps im Exhusting my room to my basement pushing the hot air down a 10x10 inch vent chase i built in my downstairs closet so it dumps into my basement can i still use my 300 sq.ft cfm fan to push the hot air down the total push down is about 15 feet ? please help THANKS

you probably need a fan that is around 750 CFM....you need this power to push the hot downward since heat rises.

thank you sir

insulated ducting helps and works wonders for heat removal. normal vent ducts help, but they still release radiant heat, which the insulated duct removes also

I agree. And flexible insulated ducting isn't much more expensive. About a dollar a foot I believe
