We use 16-foot wire hog panels in a lot of different ways on our small farm, but the best application so far has been the greenhouse my husband made with three of the panels. To make a simple, low-cost greenhouse that works well and can be moved easily, arch the panels over raised beds — using T-posts to hold them in place — and then cover the structure with greenhouse plastic.

The 4-inch mesh on the panels gives stability to the plastic, so, unlike hoop houses, our greenhouse cover has never been damaged by a snow load, and this will be our fourth year of using the same plastic cover.

Frank, "T-posts" are the metal fence posts that have a vague "T" shape if you look at the end of them.

Hey, Nice green house. Thanks for posting it. Can you show me what you mean by "T-Posts". What did you use to tie the overlapping panels. Ours is going to have to be 14' W X 24' L, and we have to have vents on the top. Will let you know how we manage that. Thanks for your time. Frank @ Sheryl Coalmont, TN

The feedlot panels 50" x 16 feet are available at tractor supply for $21.99 That means three panels would be about 12 feet long if there is 5 inches of overlap. Mary has pipe insulation on the ends to cover any wires form poking the plastic. Looks like about 6 feet wide and 5 1.2 feet high with two 2x8s on the side. Light duty 3 foot fence posts are about $3, so 10 would come to $30.

I didn't realize this was stilling floating around until a friend told us, and we are really happy that people find it at least interesting. If anyone has questions, please feel free to e-mail at

Zooming the picture it looks like the pipe insulation is on the ends of the greenhouse and 2x8 on the bottom of the sides with another piece of plywood on top of that. I would like to know if the greenhouse plastic is a fitted piece ordered in one piece or how it was installed.

Hi, super idea !! Im just wondering do these come as actual panels? Im in the uk and we have pig fensing sold everywhere but not in panels. It is heavy duty but comes in rolls. Im thinking by looking at it that it wont bend the same way as a flat panel would as its already coiled.. or i could be totally wrong and that is what you used haha! Thanks :)

Hi Mary. I just wanted to say what a lovely idea this is. Iv been looking for inexpensive green house ideas for some time. but since I don't live all that far from you in Otis Oregon it has to be able to with stand the weather we get. well, I finally found it :) I just have a few questions. 1. Is that plywood down along the bottom or is that the pipe insulation you talked about? 2. I'm going to try square foot gardening this year and they suggest using 4x4 raised beds. So my question is. If I were to put say 3 or 4 4x4 raised beds on both sides of the green house would the 3 panels still be enough? and if so would there still be enough room inside? and last but not least I promise :) with out trying to get to personal could you give me an idea of what the cost is? Thank You so much Mary and again what a neat idea. I hope it's still holding up well for you.

Mary, Could you tell us for sure what the brown area is along the bottom sides of the greenhouse? Thank you.

It wasn't mentioned, but you can see in the picture, we used pipe insulation from the home improvement store to keep the plastic from being damaged by the cut wire on the edges of the hog panels.

standard panel dimensions are 50" x 16' for those who are wondering.
