Best Mini Greenhouses Reviews

Do you want a greenhouse but you don’t have a garden space? In this case, a mini greenhouse would be an excellent option. This little kit can be placed on your patio where you can grow seasonal herbs and plants. It can be your new hobby or pastime if you have a green thumb. But before purchasing one, keep the following points in mind:

Things to Consider

Greenhouse cover

Mini greenhouses have different cover materials. Consider the weather in your place when buying one. The type of cover will dictate how much insulation and shed it can provide to your plants. The higher the R-Value of the cover material, the higher the insulation property it has.

Consider the clarity of the cover material as well. The clearer it gets, the more sunlight that will reach your plants. The amount of sunlight will affect the growth of your plants.

Local zoning regulations

Local zoning regulations won’t be a big issue with mini greenhouses. However, if you’re planning to purchase one that’s bigger than most tiered models, a quick read on local regulations will save you from the hassle.


Make sure that your choice of mini greenhouses has a strong construction. The shelves should be tied securely to the frame so you can arrange your plants without the risk of falling off.


Frames of mini greenhouses are usually made from aluminum or wood. Aluminum lasts longer because as much as wood is attractive, it can rot over time. Still, this depends on your personal preference.


Always consider the size of the spot where you’re going to place the greenhouse. Also, think about the number of plants you’re planning to grow.

Site location

Before you purchase a greenhouse, establish the site location where you’re going to put it up. It should be a spot that receives at least six hours of direct sunlight. If your greenhouse has gutters, is there a barrel nearby where you can collect water? Is there an adjacent power source?

Once you’re set with these qualifications, here are 10 of the best options for you to peruse:
