Ha, Ursula. I probably will do the same as you with a separate thermostat. So, I think I need a door to the outside (unfortunately taking prime space on the south wall), an exhaust fan, vents for air to be drawn out (that's what I meant by vents), a heating set up, an air conditioner (is yours a unit in a window? I can't remember where yours is located. Or is it central air) and poles (did you get it from Florian? How high is your greenhouse?). Too much coffee today!
