What can i use thats fairly cheap yet will help lower temperatures? Its in an attic, and there are windows outside that lead to fresh air, but have mesh over them/shades(wooden ones)..I would really like to get one of those "squirell fans" or whatever, but there like 150$++..So anything else i can do to directly take air outside? (like normal fan + air duct tubing or whatever_
You can rig an exhaust system with normal fans and tubing.... Like computer fans and stuff... Those are especially good on growboxes.
i was thinking about doing that but would that push enough air? The attic is quite large.....i guess i could box out portion that im growing in.........(usin reflective materials as curtins or something)
Or perhaps try to rig something like this to work for you? http://www.lowes.com/lowes/lkn?action=productDetail&productId=146389-53573-MWF20E-1&lpage=none
