How We Chose the Best Greenhouse Kits

The best greenhouse kits should be easier to assemble than DIY versions. That’s why we prioritized those that were the simplest to put together—in fact, some on our list don’t require any tools at all—as long as a quality greenhouse would be the result.

Durability and longevity are just as important as easy assembly. We chose sturdy greenhouse kits made of quality materials to last through several seasons. We also included some mini and pop-up versions that are a snap to pack up and store since some gardeners only need a temporary option.

To suit all types of gardeners, we chose greenhouse kits in a variety of sizes, from mini greenhouse kits to cover a potted plant or a flower bed, up to large walk-in sheds for serious planting. We prioritized greenhouses with ventilation features since it’s important to prevent a greenhouse from overheating. Lastly, we chose greenhouse kits with included accessories (usually shelving) when possible, as they offer gardeners more versatility and a better bang for their buck.

Best Bang for the Buck

Nova Microdermabrasion Mini Walk-In Greenhouse

See It

Freestanding walk-in greenhouses (like our top pick) can come at a steep price tag. Gardeners on a budget who still want some space to move around may want to consider the Nova Microdermabrasion mini walk-in greenhouse. This walk-in greenhouse is pretty roomy, measuring 4 feet 9 inches long by 4 feet 9 inches wide by 6 feet 5 inches high. Plus, it comes with shelving included in its economical price. A smaller 4-foot-9-inches-wide by 2-foot-4-inches-long option is also available.

This greenhouse is a lower-priced option because of its materials; it has a powder-coated metal frame and waterproof and UV-protective polyethylene cover. It doesn’t have any windows or vents, but the door flap can be rolled up and fixed in place for ventilation. Included ropes and anchors help anchor this greenhouse in place, but it won’t be as wind- or snow-resistant as sturdier structures. However, this affordable greenhouse is suitable for a few seasons of growing in milder climates.

• Size: 4 feet 9 inches long by 4 feet 9 inches wide by 6 feet five inches high
