Looking Beyond the HOWE 14x9.5x9 FT Polycarbonate Greenhouse? 6 Alternatives Worth a Look

How the alternatives compare

Jocisland 6x12 Walk-in Polycarbonate Greenhouse

The Jocisland 6x12 model shrinks the footprint significantly while retaining walk-in access. Its 75.6-inch height is lower than the HOWE’s 108 inches, so you may need to bend more. However, the 69.8-inch width makes it suitable for tighter yards where the larger HOWE would not fit. It features adjustable side vents for better air circulation, addressing moisture issues without requiring a massive foundation. This option suits gardeners who prioritize ventilation and compact storage over maximum vertical growing space. It lacks the heavy-duty windproof firmware of the HOWE but offers easier assembly for smaller outdoor areas.

Jocoevol 12x12 Galvanized Steel Greenhouse

The Jocoevol 12x12 model switches from aluminum to galvanized steel for the frame, offering greater structural rigidity for large-footprint gardening. Its 84.6-inch height is shorter than the HOWE’s 108 inches, but the square 144x144 inch layout provides equal floor space. Steel construction may appeal to those seeking maximum durability against heavy snow loads, though it requires trench-based installation rather than surface anchoring. This greenhouse is ideal for buyers who prioritize long-term structural strength over the lighter, easier-to-move aluminum frame of the HOWE. It sacrifices the Victorian aesthetic and wider door swing of the original for a more industrial, robust build designed for serious cultivation in varied climates.

IDEALHOUSE 6x10 ft Aluminum Polycarbonate Greenhouse

The IDEALHOUSE 6x10 model is a compact alternative at 75.6 inches high and 72 inches wide. It weighs only 86.2 pounds, making it much lighter and easier to handle than the 254-pound HOWE. This unit includes lockable doors and roof vents, providing enhanced security and climate control in a small footprint. It is designed for patio or backyard use where space is limited. You give up the vast interior volume and 108-inch height of the HOWE, but gain a structure that is simpler to assemble and suitable for small-scale gardening. This option fits buyers who need a secure, ventilated space without the bulk of a large pavilion-style greenhouse.

AMERLIFE 12x10 Hybrid Polycarbonate Greenhouse

The AMERLIFE 12x10 model offers a mid-sized footprint with a 96-inch height, which is lower than the HOWE’s 108 inches but still allows for upright standing. It weighs 245 pounds, comparable to the HOWE’s 254 pounds, indicating a similarly robust build. This greenhouse is designed for moderate wind areas and compact garden spaces, prioritizing wind-resistant construction. It lacks the specific wind rating and snow load data provided for the HOWE but offers a hybrid polycarbonate design for durability. This alternative suits buyers who want a manageable size with good structural integrity but do not need the extra height or larger footprint of the HOWE pavilion model.

PABIMIA 8x16 Aluminum Polycarbonate Greenhouse

The PABIMIA 8x16 model extends the length to 189 inches while keeping the height at 80.7 inches, significantly lower than the HOWE’s 108 inches. It features roof vents and a large floor plan, making it ideal for large-scale planting and rainwater harvesting. The aluminum frame and UV-resistant panels match the durability of the HOWE, but the trade-off is reduced vertical space. This greenhouse is best for gardeners who prioritize floor space and water collection over maximum height. It offers a different layout that may better suit certain crop arrangements or equipment storage needs compared to the square-ish footprint of the HOWE 14x9.5x9 model.

EASYHAWK 10x18 ft Polycarbonate Greenhouse

The EASYHAWK 10x18 model provides a length of 213 inches and a height of 98 inches, which is slightly lower than the HOWE’s 108 inches. It features an aluminum frame and adjustable roof vents, offering strong ventilation and durability. This greenhouse is designed for large-scale gardening in spacious backyards, providing ample floor space for serious cultivation. It lacks the 108-inch height of the HOWE but compensates with a longer structure that may better accommodate tall equipment or extensive plant rows. This option suits buyers who need a long, walk-in greenhouse with robust aluminum construction and do not require the specific width or height of the HOWE pavilion design.
