I saw a post a few days ago talking about the harbor freight 10×12 greenhouse being on sale for $500 so I decided to pull the trigger!

Any advice on how to build an interior frame to make it extra sturdy?

  1. I have a half-built greenhouse of this model in my backyard from a Covid project that never finished itself. Please do better than I did and finish that bad boy.

  2. 4×4 posts at the corners with some 2×4 tying it together. I would do a 4×4 base as well and secure the GH to that, then make sure the base is anchored into the ground.

    Secure all your panels to the frame as well, either with hardware of some sort, silicone, or both.

    Happy growing!

    We have the same one. I set it up 5 years ago.

    We reglazed it a couple weeks ago as the sun and weather had finally degraded the stock panels.

    Make sure you silicone in all the panels! I did and it’s made it through some tough winds without a frame or anything inside.
