Is the Element 6x8 Greenhouse Kit Right for Your Space?

Now accepting backorders — stock expected to arrive by mid to late December!

 

The Grandio Element 6x8 Greenhouse Kit offers the perfect balance between compact footprint and functional growing space. Designed for gardeners who want the strength and insulation of a premium greenhouse without needing a large yard, the Element 6x8 delivers durability, comfort and year round usability in a thoughtfully engineered package.

With a reinforced 1.6 mm powder coated aluminum frame and 10 mm twin wall polycarbonate panels, this greenhouse provides dependable protection from wind, cold and seasonal weather shifts. It includes many of the same high quality features found in larger Grandio models, making it an excellent choice for both new and experienced growers.

Compact Size With Full Scale Capability

Despite its smaller footprint, the Element 6x8 is built to perform like a full size greenhouse. The 10 mm twin wall polycarbonate panels offer an approximate R value of 1.89 and U value of 0.53, helping maintain a more stable interior climate throughout the year.

The classic A-frame design maximizes vertical growing space and provides ample room for shelving, trellises and taller plants. Nearly 6 ft tall double sliding doors make access easy and comfortable.

FEATURES

  • Sturdy Durability: The Element greenhouse is engineered to withstand the toughest conditions because of its sturdy 1.6mm powder-coated aluminum frame. This implies that even in challenging conditions, you can rely on its strength and durability.
  • Outstanding Insulation: The 10mm twin-wall polycarbonate panels offer excellent insulation, shielding your plants from bitter cold and keeping your greenhouse warm throughout the winter. The thickness of the panels is ideal for preserving a steady growing environment all year round.
  • Compact Yet Spacious: The Element's A-frame design not only looks great but also maximizes growing space inside the greenhouse, so you can easily grow your plants without feeling cramped.
  • Convenience and functionality: Features like the roof vents and the nearly 6-foot-tall double-sliding doors guarantee easy access, enough ventilation, and climate control. Rain gutters are even included for better water management.

Included Flat Mount Base Kit: If you're building your Element on a concrete slab or wooden deck in a controlled or fenced area, the included Flat Mount Base Kit will provide a solid foundation. The kit comes with your choice of anchors for either concrete or wooden decking. If you're building over soil, you'll need to buy the Steel Base Kit separately.

 

Optional Steel Base Kit: If you're building your Element in a windy or extreme environment, Grandio recommends using the proprietary Steel Base Kit. It's powder-coated to resist rust and decay, and its sturdy design adds extra strength and stability to your greenhouse. The Steel Base Kit also provides an additional 3 inches of headroom. It includes anchors for soil, concrete, or wooden decking. For added sturdiness, Frame-to-Base Brackets can be included in this setup.

Optional Accessories

Drain Kit - Downspout for Grandio Greenhouse Gutter Systems, designed for installation at each of the four corners of the greenhouse. It’s made to be installed directly into the aluminum frame and gutter of the greenhouse. The easy-to-install downspout drain kit includes (4) 20mm black pipes, (4) gutter attachment gaskets, and (4) side wall brackets with screws. One kit has everything needed to add downspouts to a Grandio Greenhouse.

Automatic Roof Vent Opener - Automatically opens and closes the roof vent window based on temperature changes. The opener contains a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. When the temperature cools, the mineral contracts, and a spring closes the vent, resetting the piston. The vent opens and closes gradually, allowing the right amount of airflow for cooling.

Auto Louver Window Opener - Automatically opens and closes the louver window as the temperature changes. The opener has a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. As the temperature cools, the mineral contracts, and a spring closes the vent and resets the piston. The vent opens and closes gradually, providing just the right amount of airflow for cooling. This Auto Louver Opener attaches to the left side of your louver window.

Louver Window - add more ventilation to your greenhouse. Louver window frame comes powder coated in green, with 6mm twin wall polycarbonate panels.

The Drip Irrigation Watering Kit - is a water-efficient system designed for shrubs, trees, flowers, and bushes, covering up to 150 square feet with easy expandability. It's a DIY-friendly installation with no gluing required, using high-quality UV-resistant materials. The kit includes 24 pressure-compensating drippers (20 at 1 GPH, 2 at 2 GPH, and 2 at 4 GPH) for consistent water delivery to plant roots. A backflow preventer ensures water safety by preventing siphoning into the main supply.

Moisture Control Kit - featuring Anti Dust Tape and Waterproof All-Weather Silicone Caulk, protects your Grandio Greenhouse from insects, dirt, mold, and algae. The tape's 45-micron filters allow condensation to escape while preventing algae and mold growth with a fungicidal coating. Combined with the silicone caulk, this kit ensures long-lasting protection and maintains the greenhouse's pristine condition.

Shade Net - are essential for regulating greenhouse temperatures, especially during sunny spring, autumn, and summer days. Designed to reduce intense sunlight by 50%, they help keep your greenhouse cooler and prevent overheating.

Plant Hangers - These versatile plastic hangers are designed for greenhouse use, supporting shade cloths, hanging baskets with quarter-inch hooks, and stringing taller plants or vines. Easy to install, they simply twist into the roof rafter channels.

Frame to Base Brackets - enhance greenhouse stability by securing the frame to the base, offering extra support against wind and severe weather. Each pack includes 4 EZ1 wall-to-base brackets, 4 EZ2 inner base brackets, and 16 bolt-and-nut combos.
