I was in the same situation , maybe you can keep looking and can find somewhere that has a better ventilation set up
I managed to find a place that has windows and all I need to do is put huge exhaust and intake fans at the windows
The single garage door set up is pretty hard to cool well unless you start punching holes in the side wall or ceiling
Thank you, that's exactly what I've decided to do. I am going to wait to find the right building to lease, or just end up buying so I can do what I want to.
