One feature we particularly enjoyed was the upgraded swing door with a locking mechanism. It provided easy access while keeping pests out. The 16 windows offered excellent ventilation options, allowing us to maintain an ideal growing environment for our plants.

During our testing, we grew a mix of vegetables and flowers. The spacious interior comfortably accommodated our diverse plant collection, from tomatoes to herbs. The PE cover effectively filtered sunlight, protecting our plants from harsh UV rays without compromising growth.

The heavy-duty powder-coated metal frame feels robust and withstood light winds during our testing.

Assembly was straightforward, though we recommend setting aside a couple of hours and having a helper on hand. The reinforced 140g/㎡ PE cover impressed us with its thickness and water-resistant properties. We appreciated the roll-up zipper door and mesh windows, which allowed for easy access and good ventilation.

Despite its strengths, we noticed a few areas for improvement. The greenhouse may benefit from additional anchoring in particularly windy locations, and while the PE cover is durable, it will likely need replacement after a few seasons of heavy use.

We recently set up this AMERLIFE greenhouse in our backyard, and it’s been a game-changer for our year-round gardening efforts. The 8×12 foot size provides ample space for a variety of plants, and we appreciate the 7-foot height that allows us to comfortably work inside.

The twin-wall polycarbonate panels do an excellent job of regulating temperature and blocking harmful UV rays. We’ve noticed our plants thriving in this controlled environment. The four ventilation windows and hinged door ensure good airflow, which is crucial for preventing mold and mildew.

Assembly was a bit of a challenge, taking us about 10 hours with two people. While the quick-connect system is helpful, the instructions could be clearer. However, once erected, the greenhouse feels solid and well-built. We particularly like the built-in gutter system for water collection, which we’ve connected to a rainwater barrel for sustainable watering.

The PE cover does an adequate job of protecting plants from UV rays and light rain, but we noticed it might not hold up as well against harsh conditions or prolonged exposure. For year-round use in challenging climates, reinforcing the cover or opting for a more robust greenhouse might be wise.
