Yup, John helped me a couple of years ago with this. Always over 80 degrees in there and always under 40 on the humidity. We get freaking cold up here and our warehouse is older so we just leave the heater on all the time in the screen room. We are knocking down walls / expanding / building in a few months and can't wait to redo our system. Multiple rooms connected like Tony was saying. And we don't fridge anything except beer and food
