Keeping a home garden is fun. Sure, it’s a lot of work, but being able to grow beautiful flowers and fresh produce, while being surrounded by colorful greenery sure makes it all feel worthwhile. In fact, many people find the grunt work of digging, planting, and weeding a relaxing way to spend the day. Surely, it’s more life-affirming than sitting in front of the TV looking for a new series to watch on Netflix.
Problem is, the weather isn’t always accommodating to maintaining a garden. Keeping your plants healthy as soon as the weather turns can be a daunting challenge. That’s why some people prefer to build their gardens inside a greenhouse, as the enclosed space creates a controlled environment where your plants can grow and thrive, regardless of the seasonal changes.
While a dedicated greenhouse can seem like a daunting and costly undertaking, you don’t actually have to commit to building a permanent structure to have one. For most folks, assembling one of those greenhouse kits is just a smarter, more cost-effective option. The best greenhouse kits can be just as effective as a dedicated structure, giving you an enclosed area to grow your garden while protecting it from both harsh weather and infestations. They’re durable enough to withstand the snow, rain and extreme temperatures they’ll encounter throughout the year, all while offering enough ventilation to keep the space from overheating and allow it maintain a stable growing environment.
The best greenhouse kits are relatively easy to install, with some even allowing for assembly without the use of any tools. Sure, they likely won’t last as long as a greenhouse built from scratch by a skilled contractor, but the best greenhouse kits will give you a viable growing space that should hold up for a number of years at a small fraction of the price. Plus, when you decide to grow your greenhouse, you can just build additional kits next to it, instead of having to build another extension as you would with a permanent greenhouse.
These are the best greenhouse kits to keep your garden thriving all year round.
Koksry Mini Greenhouse
Measuring just 6 x 5 x 2.5 feet (height x width x depth), this small walk-in greenhouse kit is ideal for sheltering a small collection of plants while using a narrow patch of space, just leaving enough room inside to let you move around and tend to them without having to take them out. It has a sturdy steel tube frame with six built-in shelves on either side that you can assemble using plastic connectors, as well as a clear PE cover that boasts 100 percent UV protection to keep rain, snow, and critters at bay. A set of ground stakes and ropes are included to keep the PE cover in place, with extra material at the bottom of the cover that you can weigh down with bricks to seal it from top to bottom.

PexFix 8 x 8 Portable Walk-In Greenhouse
Designed to offer enough headroom and floor area to comfortably walk around while tending to your plants, this greenhouse kit measures 8 x 6 x 8 feet (height x width x depth). It uses a waterproof PE cover similar to the smaller greenhouse above to keep the elements out of the enclosed space, albeit with a snug fit that covers every inch of the frame, so there’s no cover material dangling at the bottom. A roll-up door makes it easy to get in and out of the greenhouse, while roll-up mesh windows on the sides lets you keep it ventilated. It also comes with eight sandbags, four guy lines, and four metal mounting stakes to secure the greenhouse in place. The steel frame, by the way, is pre-assembled, with an accordion-like structure that allows it to collapse into a compact size for shipping, so setup should be pretty easy. Do note, this greenhouse kit doesn’t include shelves, so you’ll need to install those separately.

Home Complete 8-Shelf Greenhouse
Probably the best value in the list, this greenhouse kit gives you a compact walk-in greenhouse kit measuring 6.4 x 4.7 x 4.7 feet (height x width x depth), with eight integrated shelves, allowing you to tend to a good load of plants in erstwhile limited space. The frame is cut in steel with connecting joints allowing you to easily slot them together for tool-free assembly, with ropes and anchors included so you can stabilize it in place. They also throw in several zip ties you can use to secure the shelves to the frame and keep them from tipping over once they’re weighed down with your potted vegetation. The PVC plastic cover is far from the prettiest, but it gets the job done as far as sheltering your plants inside, although we do wish they integrated a bit more ventilation, so you can keep the door closed while allowing air to circulate inside.

Quictent Galvanized Raised Garden Bed with Greenhouse Cover
If you prefer a covered raised garden bed rather than a walk-in structure for your greenhouse kit, we really like this offering from Quictent. What you get is a raised planting bed made with galvanized steel that measures 6 x 3 x 1 feet (width x depth x height), allowing it to fit 18 cubic feet of soil, so you can keep a decent number of plants within the confined space.

Grezone Greenhouse (10 x 10 x 7 feet)
If you want a large greenhouse kit without spending exorbitant amounts, you might want to consider this tunnel-shaped structure, which gives you a sheltered space measuring 10 x 10 x 7 feet. It comes with roll-up doors on each end of the greenhouse, along with three windows on each side, so you get plenty of ventilation options, with mesh covers for all doors and windows, so you can keep them open without letting bugs inside. The frame is made from powder-coated steel, which isn’t the thickest, so you’ll have to reinforce it with the included guy lines and stakes, while the PE cover is UV 80+ and fully waterproof, so it will keep the elements out. If you live in a place that regularly deals with extreme storms, this probably won’t hold up (it just doesn’t feel that solid), but if you’re in a place with more forgiving winters and storm seasons, this gets you get a large greenhouse at a really affordable price even if you have to put up with the more difficult assembly.
Eagle Peak 12 x 8 Large Instant Greenhouse
Similar to the PexFix above, this greenhouse kit uses a pre-assembled frame that collapses into a compact pile, allowing you to quickly set up in a fraction of the time. Except, this is, of course, much bigger at 12 x 8 feet, so you get plenty of room inside to set up your covered gardens, with an included adjustable support pole you can put in the middle to give it added stability (it needs it, along with the included ropes and stakes, especially if you’re in windier places). The included PE cover actually feels pretty sturdy with its three-layer construction and even comes with reinforcements on corners, so those areas don’t wear quickly. The large roll-up doors (one on each end) allow for comfortable access to the greenhouse, while the low-mounted side windows allow you to close down the doors while allowing air to circulate inside. They actually have the same design of greenhouse kits available in various sizes, so you can choose one that’s more suited for your space if this one doesn’t do the trick.

Veikous Aluminum Greenhouse Kit
Available in five sizes, from 6 x 8 to 8 x 16 feet, this greenhouse kit is designed to be bolted down to the ground, ensuring it stays upright in most any weather condition. It combines powder-coatedaluminum frames with translucent polycarbonate wall panels, so we’re getting to the sturdier (and pricier) options in our list. These kits, in particular, feel like great value for money because these things can hold up to a lot. It has a wide doorway that makes it easy to bring in shelving and large plants, while a lockable door allows you to keep the kids from messing with the vegetation. There’s also a roof window that can provide any needed ventilation, which you can adjust to stay in place in any of four positions. Do note, this thing takes time to assemble, but for the time investment, you get a really beautiful greenhouse that feels sturdy to last you many years to come.
Grow House Greenhouse Raised Planter Bed
If you want to take your raised garden bed greenhouse kit to the next level, this tall protective planting bed should get you there. It’s basically a box measuring 8 x 2.4 x 2 feet (width x height x depth) that protects your plants with wooden walls on four sides and a polycarbonate cold frame top cover. Yeah, you won’t be able to admire your plants on this thing unless they grow tall, but they’ll be perfectly safe inside the housing. It has a false slatted floor that’s set at only 10 inches down from the top, so your plants get plenty of room for their root to grow, along with vents in the sides that will allow air to circulate and any excess moisture to evaporate.
Canopia by Palram Snap and Grow
While many cheaper greenhouse kits use tool-free assembly, Canopia’s Snap and Grow system just works so much easier, allowing you to put together your structure without the frustration. No, you’re not going to be up and running in no time, since you still need to snap the heavy duty aluminum frames together and slide the polycarbonate panels into place, but the assembly just feels more straightforward. It has a wide split door for easily bringing in plants and supplies, roof ventilation for circulating air, and integrated gutters that allow water collection if you want it. The kit is available in 10 different sizes, from 6 x 8 feet to 8 x 32 feet.

Monticello Growers Edition Greenhouse
Designed for growing plants you don’t want in plain sight, this 8 x 8-foot greenhouse kit comes with twin-wall polycarbonate panels that diffuse light (for even distribution among the plants), provides insulation, and makes it a little harder to make out what’s inside, so you can grow a man-eating monster plant without the nosy neighbors catching wind (fingers crossed). Those panels are installed on heavy-duty aluminum frames, so these things should hold up to years of gardening activities. Why is it so expensive then? Well, aside from the unique greenhouse walls, it also comes with its own 17,000 BTU commercial heater, thermostat, exhaust fan, folding workbench, a 48-head drip irrigation system, and automatic roof vent openers. Yeah… it’s a fully-loaded setup for the more enterprising gardeners in the neighborhood.
