Cattle panel greenhouse

Down to 12°. It was close to 32 inside that night. There are a few 5 gallons of water in there that act as a heat sink and help as well.

Even with heat sink mass, that's still really good results. I'm going to use it again this year for insulation on a couple of things I have planned.

My passive solar greenhouse at my old house consistently maintained a temperature between 12 and 15 degrees F above the outside after the outside temps hit freezing. Interestingly, the variance widened when the temperatures got lower. So when it was 20 degrees outside, it was 32 inside. 15 outside, 28 inside. 5 outside, 23 inside. I never got to check lower temperatures. The pattern could be tracked pretty easily.

I have some heavy plastic, but decided against using it for this greenhouse because of the way the wind is here. 40-50 mph gusts aren't unusual, and this will be in the direct path of most of the wind.

We have hi winds here, so I sandwiched the plastic between the cattle panels. Took twice the panels but when I built it they were still cheap

I considered that, and if prices go down I still may in the future.

How are you fastening the clear pannels to the cattle pannels?

I just used zip ties initially, but the wind kept breaking them and ripping the panels off. I decided to do as @peteyfoozer suggested and put two more cattle panels over the top for security.

It's almost October now since your post. Would you mind sharing what additions have been done and reflections.

I am till trying to decide how to close in the west end. The east end closest to the house can simply be plastic or siding since it shouldn't get the direct wind or direct sun.

I did siding for the bottom half of the west end, but it's the round section that has me stumped. I may end up using plastic as a stop-gap until I figure out something permanent.

Part of the problem is that I thought I had enough 2x4's to finish, so I didn't put that in the budget.

Still, it is currently shelter for my winter garden and working quite well for that.

Run 1x4s top of the curve, and the top of the siding. And 1 in the middle. On the inside on each end, run 1x4s vertically, screw in the horizontal 1x4s. Drill holes in the ends of all the 2x4s and wire to cow panels, top piece drill several holes and wire firmly. Could you attach the vertical 2x4s to the bottom part for greater stability?

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.
