10 Best Greenhouse Kits For 2023

Greenhouse kits are a great way for gardeners to extend their growing season and protect their plants from harsh weather conditions.

Greenhouse kits come in a variety of sizes and designs, making it easy to find one that fits your specific needs and space. They are typically made of durable, UV-protected materials that are designed to withstand the elements.

Many greenhouse kits are also designed with ventilation systems and automatic temperature controls to ensure the optimal growing environment for your plants. Some of the popular options include walk-in greenhouses, lean-to greenhouses, and wall-mounted greenhouses.

Rion Hobby Gardener 2 Greenhouse

This is a large greenhouse for those looking to transform their gardening hobby into something more professional. If you have cash to burn, you might also check out the Rion Grand Gardener Greenhouse but this is better value.

It’s superbly well built, though of course that comes at a price, and you’ll find the powder coated steel frame is very strong and safe. We also like the greenhouse cover which works very well in all weathers.

What we liked most about it was the really even light diffusion and the heat insulation. Plus, we love the adjustable roof vents.

Flower House Walk-In Greenhouse

At the other end of the scale is this cute and highly portable greenhouse kit, which is freestanding and quite small but very lightweight and can easily be dragged around to get the best light.

If you want to make some pot plants as part of your greenhouse gardening efforts then this is the way to do it. Just be prepared to move mature plants on to make space for more young plants.

This small greenhouse kit is still weather resistant and plant growth won’t stop in cold weather or in direct sunlight when your plants want to soak up all those healthy UV rays.

Erommy Walk-In Greenhouse

Not only was this one of the easiest greenhouses to put together in our tests but it comes with a high quality built in irrigation system that captures rainwater and stores it for use on your plants!

It has everything you need from an affordable greenhouse.

It’s also very strong and if you’re worried about thieves, it will give you peace of mind. The sliding door is solid enough.

However, it’s not exactly overflowing with greenhouse features if you’re looking for something a bit more complex.

It’s a quality greenhouse kit that delivers a freestanding greenhouse in no time at all. And if the local climate is a bit harsh, it’s perfectly capable of standing up to it.

Grandio Element Walk-In Greenhouse

If you want the classic greenhouse design, then this is your greenhouse. It’s elegant rust resistant aluminum frame is easy to fit in even a small garden.

This walk in greenhouse kit is designed for maximum light transmission and it has a simple adjustable roof vent to help control the internal temperature.

It’s very easy to build and we think it would look best just filled with flowers but it’s your call! Vegetables will do fine in here too. Get started in the early spring and enjoy nature’s bounty all year long.

ShelterLogic Easy Access Greenhouse

You need a lot of space for this one, it’s not your typical backyard greenhouse, but in return, you can get an awful lot out of this greenhouse kit too. It has much more to offer than most greenhouse kits.

You might want to install your own rain gutter on it though, if you’re in a stormy area or water might get trapped on it.

The roll up zippered door is a nice touch and easy to secure in rough weather. The diffuse sun light eliminating design will keep harmful UV rays off you while you work and ensure that your plants still get the light they need even in cold climates.

If you want to do some market gardening then you can easily plant a season’s worth of crops inside and harvest them all at once for maximum profitability!

Outsunny Polycarbonate Garden Greenhouse

Another more classic design that we really liked for small gardens and yards. The greenhouse coverings are very elegant and the entire greenhouse fits easily in the corner of a garden unobtrusively.

It’s cute but the reasonable price tag belies a solid build quality with rust resistant polycarbonate panels, it’s one of the perfect hobby greenhouse kits for harsh weather conditions.

We’d expect this greenhouse to last a good few years due to the polycarbonate panels. That makes it one of the better bargains of our round up.

Abba Patio Mini Walk-In Greenhouse

If you want a bigger but still quality greenhouse but don’t have a lot of cash to invest in your greenhouse just yet, then check out the Abba Patio

The polyethylene greenhouse covering rather than glass covers keep the price down but there’s a lot of room inside and the greenhouse frames are solid enough.

The whole thing produces nicely diffused light and it’s one of our favorite larger backyard greenhouse kits even though it’s a “mini greenhouse” according to the description.

Greenhouse In A Box

Yes, this is as easy to assemble as the name suggests.

It comes in a number of different sizes and if you’re worried your DIY skills aren’t up to the task of putting something together, this is going to be the best choice for you.

Super simple.

Tierra Garden Sunbubble Greenhouse

We love dome shapes and think they give a really nice look to your garden and the curve here keeps the surface perpendicular to the sun all day long and that means your plants get the most light from this kind of design.

Palram Hybrid Hobby Greenhouse

This is probably our favorite greenhouse of them all.

It’s super lightweight and we put it together in no time as a team of two (and you definitely need two people to build a greenhouse).

It’s nicely ventilated and we love the louvered roof and the anchoring pegs (which keep it together in high winds) are included in the box. It’s nicely rust resistant.
