got a question people about heat

o'k I have been using 6,,,, 4 foot doubled tube flourcent lights for the last year or so both to veg and flower the buds good but yet never tight always dense,the smoke is excellent but the weight obviously isn't going to be there!,so anyhow I purchased a 1000w hps for flowering only and it gets hot in the grow room,thought it got hot with 6 shop lights running all the time,the 1000w is twice as hot,therefore I need to vent the heat,I have no access to laundry outlet or even window,the grow room has no access to the outside other then up through the attic!.............Now up in the attic there are two breathing vents of course one in front of house other in back of house so the attice can breath,I was wondering would it be o'k to just vent to the attic and allow the heat to exscape natuarly through the attic as the new air comes in and out or should I tap right to the vent it's self that allows the air in or out?.................other words just run venting direct to the attic? and allow hot air to mix in with the attic air in hopes the heat will leave when attic breaths,,,,,,,,,,,,,,,,,,or run the venting all the way to one of the two attic vents directly????????????? any idea's/ thanks.

The attic is a useful place to dump the heat from the grow room, but depending on your situation you might have to be concerned about the odors that go up there with the heat.
If odor control is not a worry, then you might want to add a fan to one or both of your attic vents if yow want to increase air flow through the attic.
Attic temps can reach 150 degrees and a cooler attic can make it easier to keep everything cooler down below.
A gable fan can cost $60 and up, and if you can install a 1000 watt light then you should be able to do this also.

Thank's for the response dude! and no smell shouldn't be a issue for me I think perhaps i should go with a gable fan anyhow that way I can be sure of good circulation and stuff,besides I want to do everything right!and another 60 bucks won't kill me lol....
