This is a follow up to my last posting. So I have covered the cattle panel greenhouse with 6 mill plastic. It’s economical way to start. But likely will need replacement in a year or two.. Has anyone out there used better materials for covering ? Poly carbonate or Fiberglass panels ? . Higher cost but will last longer without extra maintenance .Overall I am happy with how the structure looks. The real test will be this growing season. I still do not know weather to put raised beds or build benches? Tough decision . But I will post pictures of my finished greenhouse.
