After you assemble the powder-coated steel frame and place the transparent PVC cover on top, your plants are protected from UV rays, rain, animals, wind and chilly temperatures. Use a zippered side door to move plants in and out or open the two top zippered doors for more airflow. 

Quictent claims that their Mini Cloche Greenhouse keeps the ground warm and cozy, resulting in a 95 percent germination rate rather than the usual 80 percent. To ensure you see similar results, you’ll need to place stones or bricks on the corners and on the long cover to prevent the flap from rising and to make the greenhouse more stable.

Where to buy a mini greenhouse

If you need a mini greenhouse that is a little more specific to your plants and needs, then there are plenty of retailers stocking great finds. Here are some of our preferred retailers:

Things to consider when using a mini greenhouse

The seasons
Although it makes sense to use a greenhouse during the winter to protect plants from cold, freezing temperatures, you might be surprised to discover that you can actually use a greenhouse throughout the year. 

Plant flower seeds or crops for your kitchen garden early in the spring without worrying about an unexpected frost. Start growing fall flowers and plants in the summer and store plants that won’t fit inside your home in the greenhouse during the fall. In the winter, you can actually grow cold-withstanding vegetables like lettuce!

You can find out what to plant in a greenhouse in our guide.  

Temperature, sun, and humidity
A greenhouse is meant to stay warm and toasty, but ideally, you want to keep the temperature between 80–85˚F. Anything over 90˚F will most likely be too hot for your plants. You’ll want to either open a flap to allow for some airflow or cover the exterior with shaded covering to lower the temperature. 

Don’t forget that mini greenhouses tend to create a humid environment. Watch out for molds and fungi that love humid conditions. Circulate the air (by opening one of the zippered doors) on occasion to keep the humidity in check. 

Plants placed in greenhouses are protected from bugs. However, this doesn’t mean that you never have to worry about bugs. Keep an eye out and make sure that no insects burrow into your greenhouse and set up shop. If you don’t pay close attention, they can damage your plants if they create an infestation. 

Exotic plants
Greenhouses offer a chance to grow some spectacular types of plants – especially those that wouldn’t otherwise be able to grow in your local climate. Perhaps you want to grow one of the best tropical plants or a fruit tree? Having a mini greenhouse in your backyard can take away the limitations of your local environment.
