<DIV SuperAdBlocker_DIV_Elements="0" SuperAdBlocker_OnMove_Hooked="0" SuperAdBlocker__Hooked="0" SuperAdBlocker_DIV_FirstLook="0">The box is 2x2 square and 60 " tall It is made with scrap tongue and grouve juniper wodd The little box on the left is a 50 cfm bathroom exhaust fan with a 3" vent (thats the black pipe against the wall). A hole is drilled throuth the wall and a 3" dryer vent with a flapper valve is attached to it.The door has magnets to closr and there is a small gap at the top for incoming AIR, also small 1/4 inch holes are drilled at back of box near the fan for additional air if I need it. (more pics to follow) The concept is as was posted is that under rapid fermentation the gases *CO2 which is heavier than air and the other gases will be pulled out and vented to theouterpart of the room or vented to the outside. Under preliminary test have shown good results. Ill keep everyone posted.
