Thanks. I had no idea the pvc snap clamps even existed.
That's what I love about this thread. Someone always seems to know or can find out. There's always something to learn.

I now have a design, build drawings and bill of materials and prices for a PVC greenhouse similar to what you described. I'll start off with 7'x12', but the way I designed it, I should be able to add 3' sections to the length of it for about $25/section.
Thanks for the info. It made a difference.
