You have probably seen people with a greenhouse in their backyard and have secretly envied them, wishing that your outdoor space was as large as theirs to accommodate a greenhouse, too.

Clearly, having a greenhouse has a lot of benefits. Firstly, and most importantly, a greenhouse allows you to enjoy an all-year-round gardening.

No matter the weather, you can grow your favorite plants in the greenhouse. Whether it’s raining heavily or there’s a spell of drought, nothing can hamper your plants’ growth in the greenhouse.

Mini Greenhouse FAQs 

Are Mini Greenhouses any Good?


Mini greenhouses are not meant for all types of gardening. However, for what they are designed for, they can be supremely handy.

They can be placed in small outdoor areas such as your yard or balcony. The high-quality ones can protect your plants from all sorts of elements – harmful UV rays, harsh winds, or extreme rainfalls. 

Small greenhouses work best for seed starting. This is the biggest strength of mini greenhouses, especially if you select the one with a single shelf. Mini greenhouses are also great when you want to clone your plants and already exist in your landscape. 

How Does a Mini Greenhouse Work?

A small greenhouse is designed to maintain the optimum temperature in the soil and air. This results in seed germination. 

Also, many mini greenhouses come with a plastic or metal tray that is used to keep soil or plants and sturdy plastic covering to allow light in.

Depending on the weather condition, most greenhouses can be relocated. They are compact and portable, so it’s easy to move them around and enjoy gardening at any point in time. 

Do Mini Greenhouses Protect from Frost?

Many gardeners that want to extend the growing season well into winter can do so by using small greenhouse kits. These handy greenhouses keep the air and soil suitable for the plant to grow healthily during the cold season. 

Despite the frosty weather, the greenhouse can allow the plants to grow to their full size. However, for some small greenhouses, you will need to consider added protection for your plants.

Since not all greenhouse covers are meant to resist bitter cold, you will need to consider using fan heaters, heating panels, heating beds, etc. Some small greenhouses can be moved indoors as well.

If your small greenhouse is fit for both indoors and outdoors, you can consider bringing them inside your house during winter. 

Where to Set Up Your Mini Greenhouse?

The best thing about mini greenhouses is that they can be put in small outdoor spaces such as the lawn, yard, patio, deck, or even balcony.

According to experts, you should avoid placing a small greenhouse in an exposed area where it is vulnerable to blow over. A better placement is somewhere next to a fence or wall. For additional aid, you can position containers on either side to prevent them from falling over. 


While small greenhouse kits do not offer the same luxuries as a conventional greenhouse does, they still are an excellent alternative. Unlike the latter, they are light and compact.

They can be put in small areas without any fuss. When you go shopping for the best mini greenhouse kit for your first urban garden, our list will help you make the right decision.
