The 15 Best Greenhouse Kits for Year-Round Gardening

While it’s easy to see the appeal of a huge walk-in greenhouse, they take up a lot of space and are simply not in the budget for many gardeners—so a smaller, reliable model like the Miracle-Gro Transparent Greenhouse Kit from Lowe’s is the perfect solution. At $50, this tall, slim greenhouse is a snap to assemble without tools, features a roomy interior for housing a wide variety of small plants, and is light enough to move.

Its transparent PVC cover is easy to throw over the greenhouse for extra protection from cold weather and pesky insects, and it’s a top pick for smaller properties, propping up against a shed, house, or fence, and while it’s not nearly as wind-resistant as bulkier and pricier options, this slim greenhouse is both a top pick for beginner and budget-conscious gardeners alike for the cooler months.

Dedicated gardeners searching for a greenhouse designed to endure nature’s worst for years to come will appreciate the thick weather-resistant aluminum frame, ultra-durable polycarbonate paneling, and wind-resistant design of this huge greenhouse. Not only is this large greenhouse rugged, all-season growers will love its premium insulation for a reliably toasty interior, big lockable double doors, and four adjustable roof windows that provide a premium feel to match its durable construction.

If your property is low on space, a lean-to greenhouse that braces itself against your home or shed might be your best bet. Palram’s Canopia greenhouse fits the bill perfectly due to its rugged polycarbonate panels, galvanized steel base, and aluminum frame, water-collecting gutter, and simple-to-assemble kit of sliding doors and panels. Between its minimal square footage, maintenance-free design, and relatively inexpensive price tag, there’s a lot to appreciate about this greenhouse.

It’s gorgeous, sports a collection of durable polycarbonate panels, and is simple to assemble. But the nearly $16,000 price tag limits this beautiful greenhouse to hardcore gardeners who can afford to go all out. However, if price is no obstacle for you, this charming, cottage-like greenhouse features adjustable windows, a large lockable door, and a sizable area of 120 square feet, allowing you to set up shelves, lighting, plumbing, or whatever you need to make the greenhouse of your dreams.

If you live in an area known for stormy weather, the thought of a windy day ruining your investment may keep you from buying that greenhouse you’ve always wanted.

If durability is your biggest concern when shopping around for a greenhouse, the ultra-touch and extra-long aluminum frame and thick commercial-grade polycarbonate panels are sure to last for a long time to come.
