I don't think the non-woven floating material would provide enough warmth for the cold snaps I have.
I'm thinking of clear plastic, that might have to nurse a small bed through a few episodes of a week of longer of 10-15 degrees of frost. With a somewhat cold-hardy crop, they would only need the protection occasionally, but then they would need more than 5-10 degrees which I thought that the woven material gave.
Here, usually snow melts too quickly to serve as a "blanket".
I'm also hoping that (some day) hoop tunnels would be enough to get tomatoes into the ground a month earlier in the spring or early summer. The problem there is not so much COLD snaps as "nights hardly EVER stay reliably above 50-55" until July. Maybe the non-woven stuff would be enough for that.
But I know that I'm not going to find enough time and energy in the near future to get this ambitious. I HOPE to get some weeding done, then peas, bok choy and lettuce planted while it's still spring.
But thank you very much for the offer!
