So damn jealous!
Your room is just incredible.
I'm so jealous that I want to come over with a can of black spray paint and tag up those beautiful interior walls. You know... lots of little "Kilroy was here" drawings with Tead instead of Kilroy.
So, I see your hot day temp info. Where does your input air come from? Are you pumping hot exterior air into you garden? If so, have you considered some sort of system to switch input between house interior air (presumably cooled) and exterior air when it's cooler outside.
I change my input based on outside temps.
