The Grandio Elite 8x24 Greenhouse Kit is built for gardeners who want a spacious, insulated and weather-ready structure that can handle real year round growing. As the largest size in the Elite series, the 8x24 offers extensive room for raised beds, shelving systems, trellised crops and propagation stations while maintaining the same premium materials and durability found across the lineup.

Its barn style design provides impressive interior height and headroom, making it comfortable to work inside while supporting tall plants and efficient vertical growing. With 10 mm twin wall polycarbonate glazing and a reinforced aluminum frame, the Elite 8x24 is engineered for long term reliability in a wide range of climates.

Built for Serious Gardeners and Expansive Growing Plans

This greenhouse offers the insulation needed to extend the season and protect plants during cooler weather. The 10 mm twin wall polycarbonate panels deliver an approximate R value of 1.89 and U value of 0.53, helping regulate warmth and reducing heat loss.

The oversized footprint provides the space needed for diverse growing setups, including hydroponics, microgreens, fruiting crops and overwintering sensitive plants.

BENEFITS

  • Extreme Durability: This greenhouse is built to last with a 1.6mm profile aluminum frame that can handle the elements. The metal frame won't bend, melt, or crack like PVC structures do, so your investment will last for years.
  • Better Insulation: This greenhouse's 10 mm twin-wall polycarbonate walls are the perfect thickness for keeping heat in during the winter. With an amazing R-VALUE of 1.89 and a U-VALUE of 0.53, it minimizes heat loss, making it a great place for plants to grow even in the winter.
  • Elegant and Spacious Design: The barn-style architecture is not only nice to look at, but it's also useful because it gives you more room both vertically and horizontally. This means you have more room to grow plants, put shelves together quickly, and move around.
  • Built-in Air Flow and Easy Access: The Elite 8x24 is designed to let air flow and be easy to get to, with six roof windows, built-in rain gutters, and gliding double doors. The doors are hung from above so they don't get stuck, and the nylon wheels make them easy to move for a long time.
  • Ready for Any Situation: The Elite 8x24 Kit comes with a snow load kit for extra support in snowy areas. This keeps it strong even when it's full of snow, giving you peace of mind all year.

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.
