Do you have a green thumb but not enough yard space for a full-fledged garden? Have you ever considered gardening with a mini greenhouse? Whether you’re an expert gardener or just looking for an attractive centerpiece for the living room, a mini greenhouse could be just what you need. Some species of plants need starting earlier than their specific growing season, especially if you’re starting from seed. If you live in a colder than average region, you’ll need to start these plants inside. A mini greenhouse is the perfect piece of equipment for the job.

A mini greenhouse also allows you to extend your overall gardening season. Just move your outdoor plants inside and place them in a mini greenhouse on the windowsill or a table in a well-lit room. When warmer weather returns, you can return said plants to their former location outside. After you build a mini greenhouse, you will wonder why you didn't do it sooner!

What Exactly Is a Mini Greenhouse?

A greenhouse is a structure equipped with walls and a roof consisting of see-through materials such as plastic, plexiglass or traditional glass. The primary purpose of a greenhouse is to regulate the climate in which plants grow. For example, growing lettuce outdoors in the wintertime or cultivating tropical plants in a much harsher environment.

A mini greenhouse, therefore, is just a smaller version of a full-sized greenhouse. Mini greenhouses can be used indoors or outdoors, unlike their larger versions which are strictly outdoor structures. However, for the most part, mini greenhouses are typically found inside the home. Sometimes mini greenhouses are used for storing outside plants inside during the winter. Other times they are used for growing various types of plants indoors, such as kitchen herbs, flowers, fruits, and vegetables.

That said, as I mentioned above, mini greenhouses can and are also used outdoors. Even though these outdoor mini greenhouses are somewhat massive compared to the windowsill and tabletop mini greenhouses found indoors, they are still considered mini compared to the much larger traditional greenhouses.

What Are The Benefits of Using a Mini Greenhouse?

So, now that we’ve covered what precisely a mini greenhouse is, let’s go over some of the main benefits of using one. Aside from looking awesome and being a good conversation starter, a mini greenhouse has many versatile benefits for plants including:

  • Stabilizes temperature
  • Improves humidity
  • Creates higher levels of carbon dioxide, promoting faster plant growth
  • Protects your plants from pests such as animals and insects
  • Reduces harmful plant diseases
  • Extends gardening season
  • Looks attractive indoors
  • Makes a great hobby

A mini greenhouse is also an excellent and interactive way to educate children about plants and horticulture in general. Not only are they great for inside the home, but they also make an excellent addition to classrooms and offices.

Where Can I Use a Mini Greenhouse?
