Well, the greenhouse isn't holding heat. I put a jar lid over the hole in the flower pot to see if that would help. I didn't want to set it up too early because I didn't want the greenhouse to get too hot. Around mid morning the sun had warmed it to 70F, but then I opened it and let everything get some air for a while.
I don't need to get it back up to 70 overnight, but it's only 50F in there at the moment and the temperature has started dropping outside. Wind's picking up too. Managed to brace the back shelves and now it's really leaning in the front. I'd like to knock the person who designed it upside the head.
I need to replace it and I'm debating between pvc and salvaged wood.
