lmao..im just back from hardware store with 2 dimmer switches and read your post...lol..so im thinking along the right lines...when you say larger vents im guessing you mean the square ones..which are adjustable....as opposed to the circular ones that just let in loads of air...and if i read your message right..i should put one vent on side say 8 inches off floor....and the other vent on other side panel at top????????hope this is right as i will be drilling pretty soon.so if im wrong please correct mate..trhanks
