What I have in mind is effectively an unheated structure strong enough to last in snow country, permanently covered with a white material to keep it shady enough for hardy landscape propagation and less prone to heat up in the winter. I'm thinking of this as a great way to keep deer & weed seeds out of my propagating bins, even as bottom-heated beds would give me a great place to keep them to encourage root growth as the tops remained cold.
Do you think these ideas are compatible? I don't know of any greenhouses of this nature, unless I've seen them and just didn't recognize them as such.
Thank you!
