The Admiral has declared I have to many unfinished projects to build a proper outdoor shelter and for various reasons not ready to cut a hole in my garage wall right now. Bought a el cheapo Broan hood at Menards and am going to vent under the garage door for now. Specs call for a 6" duct, but from all the other posts I have seen it appears most have vented with 4". 6" flexi is 2x cost. Please comment if you use 4 or 6" and how it works out for you.
Thanks all
