You might be looking for jocisland 6x12 ft walk in polycarbonate alternatives if the original model does not fit your specific space or budget. The Jocisland greenhouse offers a reinforced steel frame and quick-connect assembly, which suits buyers who need a sturdy, fast-to-build structure. Its 4mm polycarbonate panels provide UV protection and ventilation through adjustable roof vents.

Others might want a smaller footprint for narrow yards or a larger area for serious growing projects. The alternatives in this list were chosen because their published specifications overlap with the original product. Each option shares key features like walk-in access, polycarbonate panels, or similar dimensions. You can compare sizes, frame materials, and additional features like lockable doors or power outlets. This guide helps you find a model that matches your exact gardening needs without compromising on quality or durability.
Our top pick: Jocisland 6x12 Walk-in Polycarbonate Greenhouse.
How the Alternatives Compare
Backyard Discovery Bellerose 9x6 Cedar Greenhouse
The Backyard Discovery Bellerose uses a 9x6 footprint instead of the Jocisland’s 6x12 layout. This wider, shorter design offers 82.3 inches of width and 112 inches of height. It weighs 798 pounds, making it far heavier than the steel-frame Jocisland. The Bellerose includes built-in shelves and power outlets, features the original lacks. You gain thermal efficiency and storage but lose the long, narrow corridor style. Pick this if you need a compact, utility-ready space rather than a long planting aisle.
IDEALHOUSE 6x10 ft Aluminum Polycarbonate Greenhouse
The IDEALHOUSE model measures 6x10 FT, which is two feet shorter than the Jocisland’s 12-foot length. It stands 75.6 inches high, slightly lower than the Jocisland’s 76.8 inches. Weighing only 86.2 pounds, it is much lighter and likely easier to move. This unit includes lockable doors and roof vents, matching the Jocisland’s ventilation focus. You trade floor space for a lighter, more compact structure. Choose this alternative if your yard is smaller than 12 feet or if you prioritize portability over maximum growing area.
Backyard Discovery Willow 9x6 Cedar Greenhouse
The Backyard Discovery Willow shares the 9x6 footprint of the Bellerose but differs in color and weight. It weighs 571 pounds, significantly heavier than the Jocisland’s steel frame. Its height is 94 inches, offering less vertical clearance than the Jocisland’s 76.8 inches but with a different profile. It includes fixed shelves and cedar framing, which the Jocisland does not offer. You gain integrated storage and a natural wood look. Select this option if you want a stable, shelf-equipped greenhouse that fits a square footprint rather than a long rectangular one.
PABIMIA 8x16 Aluminum Polycarbonate Greenhouse
The PABIMIA greenhouse is substantially larger at 8x16 FT. It is two feet wider and four feet longer than the Jocisland. The height is 80.7 inches, providing more headroom than the Jocisland’s 76.8 inches. It features roof vents similar to the original. This model sacrifices compactness for significant interior volume. You get a structure suited for large-scale projects rather than small backyard plots. Pick this alternative if you have ample space and need a wider base for extensive gardening equipment or multiple plant rows.
MUPATER 8x8 Wooden Polycarbonate Greenhouse
The MUPATER model offers an 8x8 FT square footprint, contrasting with the Jocisland’s 6x12 rectangle. It stands 90.6 inches high, taller than the Jocisland’s 76.8 inches. Weighing 283 pounds, it is heavier than the Jocisland but lighter than the cedar competitors. It includes lockable doors and windows, matching the original’s security features. You gain a square layout and extra height but lose the long, narrow aisle. Choose this if you prefer a symmetrical base and need more vertical space for tall plants or shelving.
Backyard Discovery Savannah 14.5x12 Cedar Greenhouse
The Backyard Discovery Savannah is the largest option at 14.5x12 FT. It matches the Jocisland’s 12-foot length but is much wider at 150 inches. It stands 125 inches high, offering significantly more headroom. Weighing 1579 pounds, it is a permanent, heavy-duty structure. It includes shelves and integrated utilities, which the Jocisland lacks. You trade the quick-assembly steel frame for a massive, utility-equipped cedar build. Select this alternative if you need a permanent, high-capacity workspace with built-in power and water connections.
