Corrugated galvanized steel roof panels with a frame of 2x4s. I'd never built anything before, so I had some issues with bowing almost immediately, which just got worse over winter as the soil settled. We put in some braided steel cable braces last month, ratcheted it all back into place, and it's not budged at all!
I planted way too many tomatoes because I didn't get any last year, and now I'm going to be swimming in them!! I'm currently battling armyworms though, hopefully I actually get a harvest :)
Well it keeps the deer, rabbits, and moles out. Squirrels however dug up 75% of my corn :|. I'd put a fence roof on but the joro spiders will take over.
Thanks! It was two leftover 4x4 beams from a neighbor's project that didn't get used. The caps are actually solar light caps that I bought on Amazon :)
