Concrete Slab or Wood Deck Installation: If you plan on constructing your Summit on a concrete slab or wooden surface, the included Flat Mount Base Kit will offer solid footing. The Flat Mount Base Kit includes your choice of anchors for concrete slab or wooden surfaces.

In-earth Installation: If you plan to install your Grandio Summit Greenhouse directly into the earth, we highly recommend our Steel Base Kit with Earth L-Bolt Anchor Kit. The Steel Base Kit is powder coated to resist rust and decay and is designed to be buried into the ground or back filled with gravel providing a solid foundation to combat wind and other extreme environments. Just select “Base Kit (Earth L-Bolt Anchor Kit)” when you checkout and you’ll get everything you need
