It should be a fun project. I built a greenhouse, 7' wide, 7' high and 12' long using 1/2" PVC. In my case I drilled 3" into the edges of the wood 2x6 raised bed frame, and inserted 12" rebar, so that the PVC uprights slid right onto them. How are you securing to the ground so the whole thing doesn't blow away? Also, be sure to peak or slant the roof so water sheds off, or the weight can collapse it. Even with really tight fabric it will stretch in time and sag, creating a pond effect. I bent 8' PVC to make a rounded top, but still had to go inside and bang off snow when we got 2" or more. I never glued any of the PVC, just stuck it tight together, because the clear plastic film I used is stapled to the wood on the bottom and keeps it together, and I can easily disassemble if I need to. Post a picture when you get it done, or even better, a few showing your progress.
