- 6mm twin-wall polycarbonate panels for insulation and even light diffusion
- Wide 3 ft 6 in double sliding doors that fit carts and wheelbarrows

- Rated for 76 mph winds and 25 lbs per sq ft of snow when properly anchored
Best for: year-round vegetable and flower growing, seedling production at scale, and gardeners in snowy climates who want a structure engineered for winter out of the box. An optional back door transformation kit converts the rear wall into a second entrance.

Frequently Asked Questions
How is the Ascent different from the Element? The Ascent is taller at 7 ft 9 in, wider at 8 ft, has wider doors, and includes the steel base kit and snow load kit as standard, so it is winter ready out of the box.
Which anchor option do I need? Wood for decks or timber bases, Concrete for slabs and patios, Dirt for soil or grass installs. The included steel base works with all three.
How hard is assembly? Components are pre-cut and labeled with hardware and tools included. Two people typically finish in 4 to 8 hours, and larger panels go easier with a helper.
Is 8x8 big enough? It is a spacious starting point. If you want multiple beds plus staging tables, step up to the 8x12 or larger, which also add roof vents for airflow.
