Cattle panel greenhouse

You could saw kerf the back side of a 1×4 to make it bendy. Kerf depth and spacing is dependent on how much you need it to bend. Works best with a clear board (no knots).

Diagram? What I think you're saying is three 1x4's the length of the greenhouse, tied in by a framework on either end and wired to the cattle panels.

Yup. If you can’t attach the verticals to the bottom frame, then sink posts in the ground on the inside to fasten the horizontals to.

I did a temporary fix on the west end, but completed the east end and the doors. Even facing the house, the wind is still fierce enough to throw the doors open. I have temporary latches on until I can figure out a reasonable solution. In hindsight I should have hung the doors so they opened out, in spite of the space constraints (the east end faces the house and has about three feet between the greenhouse and the house wall).

For the floor I used layers of an old trashed tarp, covered with cardboard. The base is sealed along the edges and I put in a few water bottles today for thermal mass.

Still not well sealed, but at least keeping the frost off the plants. More sealing to come after I fix a couple more structural problems.

Without being sealed, before any thermal mass and before the floor going down, it was running with the outside temperature but not as wet.
