SSIE1620BRNTW SolarGro Cascadia Greenhouse Kit 16' x 20' - All TwinWall - Straight Eave Brown



Our premier insulated greenhouse

One of our most popular greenhouses, the Tahoe is also the easiest to build. Assembly is simple and intuitive, with nothing to cut, drill or bend. With sidewalls at 5'-7" high, there is plenty of headroom inside, and you can add shelves to maximize your growing space.

The roof slope is lower to reduce heating costs in winter, but steep enough for snow to slide off whenever the greenhouse is heated by the sun. The eaves are designed to accept gutters if you want to collect rainwater for your plants. This modular system is easy to customize, and sections can be added later to extend the length.

Actual Size (Width x Length x Height):
16' 9-1/2" x 20' 10-1/2" x 9' 5-1/4"
Eave Height is 5' 7"
Width x Length are the outside to outside foundation dimensions. It is imperative that the foundation is built to these exact measurements.
