There are several benefits to buying greenhouses in the spring—including low prices. A greenhouse kit sale is the best time to stock up on everything you need to nurture your plant babies.

For those who have several plants that need a home, this walk-in greenhouse is the next step up from one on wheels.

Stakes help secure this greenhouse to the ground to resist wind, giving it an edge on simple plant covers.
Even raised flower beds require a little TLC sometimes. This mini greenhouse fits over most standard-sized garden beds and offers protection against the wind, dust and curious animals.

It comes in two colors, so it’s easy to match with your decor if you debut it indoors.
Plastic greenhouses are perfect for the average DIYer. They’re easy to work with, durable and don’t break as easily as glass during wind or hail. Because of that, this hobby greenhouse tunnel is a solid pick for novice gardeners and handymen. The moderately sized 120’x26.2′ dimensions offer plenty of space for plants, and easy installation has it up and running in no time.

The largest greenhouse kit at a behemoth 8’x16′ is the Snap Grow greenhouse, available at a savings of $1,190. An innovative SmartLock connector system simplifies setup, so you can have it up and running in no time. The split door and vent windows—made from the same tough, crystal-clear SnapGlas as the panels—come preassembled out of the box. Anchor it to a foundation like concrete for a stable greenhouse that won’t bend or flex in bad weather.
Before shopping for a greenhouse kit, here are a few things to remember. First, consider the size of the greenhouse. You want to make sure that it can fit in your space and isn’t going to construct our home or any exits. Next, investigate the materials from which the greenhouse is made. Even though glass greenhouses are more expensive, they are more durable and allow more sunlight in. The other option is plastic, a cheaper material that is still durable but more susceptible to damage from the sun and wind.

The term “greenhouse kit” refers to any structure purchased to protect plants from the elements. There are many different types of greenhouses, from cold frames to solar-powered hot houses. Greenhouse kits are available in a wide range of prices, from as low as $50 to more than $10,000 for specialized structures.
