I am going to cover the floor and ceiling with some mylar I have laying around. A dehumidifier will be taken out of the garage storage and put to use in the basement. Filters: I figured if using such a big fan I could put a few filters BEFORE it entered the cab. not only would it slow down the fan, but in turn filter the air the plants are getting....also, those filters are about 3 feet away from my homes heating unit, would it be possible to suck in some of the CO2? Prob not, just a thought, will continue with my milk containers filled with water, sugar, and yeast!! Just looking thru old folders of pics and thought I w0ould upload a random!!
