I know the whole cool room topics have been discussed quite a bit on here and I have looked at those post. I was curious if anyone has used the cool bot system and if so how did it work? Also was thinking about installing the Cool Calf Safe Door system if I end up building a cool room and was curious if anyone had purchased one of these? My last question is how does everyone get fresh air into there cool room? I seen on some post about using a exhaust fan for a bathroom but would like some more info on that also. Thanks
