9. There are, and I don't have a link. light tubular steel car covers,

garages, whatever one wants to call them, that have covers which range from tarps to clear plastic. They sell them at Harbor Freight and other outlets.

We bought some plants the other day, guy had one of those from a discount place, was missing the cover. He contacted the mfr and they didn't have the standard tarp, so they sold him a plastic cover, UV resistant, has what looks to be cotton twine sealed in for reinforcing, perhaps. He now uses it for plant starts and hardening.

You could put plastic on and just add a tarp or shade cloth on top in the summer.

We live in a place that goes between Zone 4 and 5, our last frost is usually around June 1. In back of us is a concrete building with a wood frame extension. They put the rigid plastic that is sold in 4 x 12 sheets at Homer around and on top, said last winter in the snow, when the sun was shining it was 113 degrees F, without supplemental heat.

Friends that we buy eggs from heat theirs when needed with a small electric heater, grow tomato starts for sale.
