New 8x8x7 room.. Vent help

Hey guys this is my first post my friend has a new room 8x8x7 with one 1000W light and is having issues with Venting idea.. the room is covered in PVC Plastic.. the room is in the upstairs bedroom and he does not want to vent into the attic... Does anyone have any ideas? Thank you for you help.

you should look on ebay and check out the pyrex bake around it is a 4in tube which can be ducted with a inline fan can help greatly in reducing the temp and the ducting can be sent out a window or anywhere, however a carbon filter would be a good idea to prevent smell...

I wouldn't advise you to vent any hot air outside. If I was worried about venting into the attic, I would just vent the hot air throughout the house.

Your attic has fans that draw out hot air when its gets to a certain temp. The air coming out of your grow room wont be hot anyways. 70-80 degrees if you're doing it right. Attic temps reach up to 100 plus degrees on a hot summer day. If anything, your grow room temp would lower your attic temp and help push out the hot air.

I'm sorry if this isnt what you wanted, i didnt understand you very well.

Sorry for the confusion in the question ... basically the room is upstairs and it is probably the hottest room in the house there is a concern for venting in the attic because people said that's where pigs look.. is this true? also the attic main fan was taking out... does anyone have suggestions on how and where to vent the room properly? the walls was a thought..? thank you for your help
