Cattle panel greenhouse

[CrealCritter]

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.
