Geodesic Greenhouse

Thanks all, my first "mention"!

I was pleased with my "Covid19" foundation method - I wanted to use what I had around.

So - I designed it first in CAD to efficiently use the connectors and tubes I had salvaged.









Then, I laid out three 24'-long rows, 12' apart, and then put a pin every six feet along the rows - so fifteen pins, pretty correct in X and Y, but varying up and down with the ~2' slope of the yard. Next, I drove 3' sections of galvanized inch-and-a-half pipe at those pin positions, just to where they were getting hard to move - kept them vertical with a bubble level made for fence-posts.

Then, I packed in some random amount of dry sand, hard with a heavy iron rod that just fit. Finally, I mixed up and poured about a half inch of polyester resin (like for Fiberglas work) onto the sand in each one - when it dried I drilled a weep hole right at the cured surface.

Now - I had fifteen "hard point sleeves" with seats of varying heights. I surveyed them with a dumpy, or contractor's level on a tripod. This allowed me to cut all the legs to the individual heights to make their tops all within less than a sixteenth of a perfect level plane.

Once the legs were set in and the structure was built and triangulated and plumb, I packed in more sand and then mushed in a cone of black roofing repair cement -
