Hi everyone. I put together this greenhouse a few weeks ago and had the tarp on it. We got an insane wind storm last week, so I removed the tarp in a panic so the frame wouldn’t break. I had pavers lining the bottom on the sides.. which did nothing against the wind.
My question is, are there any suggestions you all have that I can do to make this more stable when the tarp is on? I was thinking about adding 2×4 wood framing somehow, but don’t want to get started until I have a solid plan that could work, obviously. I’ve thought about T Posts on each corner.. attaching to the metal as well. Just something that will help it not sway quite so drastically. TIA

Heavy duty screw in anchors that you can tie both the frame and tarp to
Before doing anything, remember that what you *do*, you’ll need to be able to *undo*. Greenhouse plastic will eventually turn opaque, get torn or otherwise damaged to the point it’ll need replacing eventually.
For me, I would build a frame of 4x4s around the entirety of the base, further anchor those to the ground at the 4 corners using [ground anchors](https://www.amazon.com/VASGOR-Anchors-Camping-Canopies-Securing/dp/B0BFMPCGNL), anchor the greenhouse frame to the 4x4s [using padeyes](https://www.amazon.com/Branded-Boards-Stainless-Galvanized-8-Pack-Silver-M6/dp/B08WRK5D7B), then for the greenhouse tarp, cut it so it is long enough to drape entirely over the 4x4s, and secure the tarp to the 4x4s using 2x4s and 4″ screws, so that the 2×4 is sandwiching the tarp to the sides of the 4×4.
This way, the greenhouse plastic isn’t just being held down at certain points, where if one fails, that is even more pressure placed on the other points; there is contact all along the entirety of the base where it is sandwiched between the 2×4 and 4×4. Plus, with the entire greenhouse secured to 4x4s and further anchored to the ground, it [reduces the chance of it going airborne](https://www.youtube.com/shorts/1_wD2WZwPeA).
Is that a bit overkill? Yeah, some would say.
Is it poly clear plastic?
I’d recommend putting on the plastic, then securing rope zigzagging over each bow back and forth, tied to good stakes in the ground
The plan I had made up has big wooden pallets as the floor to elevate things off the ground a little, adds weight, support and anchor points, can just use bricks/blocks placed inside the pallets where the forks would go to help secure and hold it down as well as tent peg style U-Bolts that wrap around the frame going down into the ground.
