Mockup of Base

Each strut will be cut with at a 12-degree angle, recessed so the connectors fit flush.
 For the mock-up, I have only attached a connector on one side.
I will have to disassemble all before I start to dig, but I needed to know the exact diameter of the greenhouse.
 Here is the completed mock-up.  With the added length of the connectors, total inner diameter is 18.5 feet.
 After centering the blocks that will become the base, I sprayed the outer perimeter orange.
 3 yards of stone to protect the underground tubing and make the floor of the greenhouse.  It doesn't look like it will be enough, but I will make it work.
 1" foam board, cut into 24"x36" chunks. This will protect the foundation perimeter from frost.
