I bought the 6x8 greenhouse and am really pleased so far. I'm concerned however when spring arrives about opening the vents. I'm not always home to monitor the temperature. Has anyone tried their window vent openers? I think they are around $22 and I don't wanna waste my money. Thanks for any help.
Harbor Freight greenhouse question
I use the auto-opener on one window. I think it would work better if I has an opening on the other side, but it does let the heat out. I don't use it in the winter here in MO, if the GH does get hot inside it is for such a short time that I don't worry.
