beautiful addition

I bought this lean to greenhouse to fit onto a garden house that I designed as a passive solar addition to my garden. It's a beauty and I couldn't be happier with the quality and durability of the materials. Easy to construct and it's going to last many productive growing seasons. I'm growing a lemon, 2 limes and a grapefruit bush and have started some flats with winter greens and herbs.

Lean-to Greenhouse

This unit was easy to erect. The instruct ructions were great and easy to follow. It took 2 of us 2 days to completely erect the system. The only thing we had left to do was to install the heater. It is very strong and will provide good service based on what I see after assembly.
