I like those hoop houses! I'd like to be able to cover my entire main garden that way, but I can't afford that much material this year. At least I have my new greenhouse that we built last year. I'll be growing a lot of my tomato plants in it this year. They like the heat, but I have to remember to help them with pollination. The bumblebees seldom come into the greenhouse, so I have to help the plants myself.
I put up a couple of posts about my greenhouse here on steemit, if you'd be interested in checking it out.
