Thanx. That's exactly what I was looking for... . My complication is that the door to a warm area is blocked by the last batches of plants that I haven't found places for yet. The door i am using opens to the unheated garage . Consequently I really don't move plants easily anywhere. And there is not enough open volume in the greenhouse to have a setup there. It's also so crowded in the greenhouse, that even moving the plants is an effort. . One might think that I have a 'gotta have it' kind of problem to solve first. Those folks would clearly just be confused. Thanx for sharing your setup description. It's helpful.
