yes it is currently unheated. don’t really need heat, however, if temps drop to freezing i can put a small heater in to prevent damage. We start the seedlings in the house to sprout them, then we transfer to the green house to toughen them and give them better sunlight.
Got a shock when I saw your Montana flag LOL! (Did read down further though).
Thanks, I’m in Zone 6 so I guess that would work for me in a month or so.
