Steps:

1. Greenhouse kits require a simple foundation, basically a perimeter of landscape timbers with a gravel floor. Based on the measurements given in the kit, make a square, level perimeter of 4x6 landscape timbers.

2. Nail the landscaping timbers together and spike them to the ground using landscape spikes. Check for square by measuring opposite diagonals. When the diagonal measurements are identical, the box is square.

3. Lay down landscape fabric to eliminate the weeds, then dump in 4 to 6-inches of gravel. This will assist in drainage.

5. If desired, build and secure workbenches for the inside of the greenhouse. Bolt a 4x4 post to the landscape timber bottom frame. Then, make a perimeter of 2x4s. Next, make an inner perimeter of 2x2s, measuring 1-1/8 inches from the top of the 2x4 frame. This will give you a ledge to set the shelving boards on. Once that’s done, just lay in the shelving boards.
