The Best Small Grow Tent – CoolGrows 2x2x4 Review

CoolGrows: One of the best small grow tents for sale

There’s no question the most significant issue when it comes to urban gardening is the lack of space. Hydroponics has made it possible and easier to start cultivating plants without needing soil, but this still requires gardeners to have the extra space at home to build their hydroponic setup.

In these instances, the best answer to both the soil and the lack of space problems is the innovative grow tent. This space-saving, handy gardening tool makes the perfect substitute for a greenhouse.

The issue with many grow tents, however, is still their size. Although these tents are designed to be compact, they still take up a considerable amount of room; not something urban gardens with very limited space will appreciate. This is where the CoolGrows 2x2x4 Feet Small Indoor Mylar Hydroponics Grow Tent comes in handy.

For this review, we will talk about the CoolGrows 2x2x4 Foott Small Indoor Mylar Hydroponics Grow Tent and the many unique features that make it stand out. We will also discuss the product’s pros and cons to help you make a decision when it comes to purchasing a grow tent.

Growing plants indoors has been made easy and accessible by the CoolGrows 2x2x4 Grow Tent. One of its biggest advantages is its compact size, which is almost twice as small as other grow tents on the market.

This means it can comfortably fit in smaller spaces, allowing indoor gardeners to plant, sow, and grow, even with very limited space. Another advantage that gives this grow tent an edge is its affordability.

Granted it may be smaller than other tents, but it also means those who are just dabbling in indoor gardening will not have to spend twice as much for a grow tent. This makes a great beginner grow tent because of its price and its size.

There’s no need to worry about spending loads of time caring for too many plants as the size of this grow tent is just enough to give you the right amount of plants. This tent is also fitted with several vent windows to allow ample airflow, and also allows you to peek at your plants very quickly.

The size of the grow tent also makes it easy to put together; while some users struggle with the bigger and bulkier grow tents, this one can be managed and assembled by just one person.

The CoolGrows 2x2x4 Hydroponics Grow Tent is also sturdy and reliable. The metal poles offer great support, even when you add a few more light fixtures. The tough canvas used for the body of the tent, coupled with the commendable stitching, makes this affordable grow tent supremely lightproof, ensuring your plants get the proper amount of light, even with the absence of regular sunlight.


One of the CoolGrows 2x2x4 Grow Tent’s most significant advantages is also considered a disadvantage: its small size. Although many users appreciate the compactness of this grow tent, it also limits the number of plants they can grow.

And while many people would consider buying this grow tent again after they have tried it, they tend to prefer buying a much bigger one, which costs more. Luckily CoolGrows offers a variety of sizes so you can upgrade your grow tent when you feel ready to expand your indoor garden.

Also, beware of the lack of an instruction manual. Some users have mentioned this issue, but they didn’t encounter any trouble in assembly, even without the help of a manual. Others have also noted that they were shipped a set that was missing a piece or two, but a quick message to the manufacturer solved this dilemma.


Users have nothing but praise for the CoolGrows Small Hydroponics Grow Tent because it is a truly exceptional product that lives up to an indoor gardener’s expectations. First-time users of grow tents love the simplicity and functionality of this grow tent. It even encourages them to continue and expand their indoor garden.
