Welcome to DC Gardenerking.
I see your picture has both the gardener King and gardener Queen in it.
Any pic's with the poly and windows installed?
Is that a 4' level? If so is your green house aprox. 32' X 16' ?
That's a nice size and I'm jealous.
Why the angle on the tops of the studs? Guess a pic of the roof would help explain.
Are those the post anchors you simply drive into the ground that go about 30" deep?
Is there any footing under the blocks other then gravel?
Sorry for all the questions about building on a cooking forum but it's my nature as it's what I do.
Looks great and keep us informed on all the tasty veggies it produces for you.
