It also features an observation window, a removable waterproof floor tray, and five dual-cinching sockets in multiple sizes.
Reviewers have tons of positive things to say about this tent’s size (which has been called “tabletop”). And it seems to be great for beginner indoor gardeners as well, with one person saying that the tent “definitely served its purpose well. So well that my plants outgrew it.”

How we chose the best mini grow tent
The best small grow tents offer more than just their compact size. Assets like superior craftsmanship, innovative features, and great customer service were essential. Plus, indoor gardening can be expensive. You won’t find many tents under $50, and most require additional equipment and supplies. So we made sure that every model on our list had evidence of being a long-lasting investment.
All Mylar material had to be at least 600D, and we only chose tents made with durable metal frames—no plastic allowed. We also looked for features that made setup a little easier, like adjustable ports and automated controls.
Who this mini grow tent is for
Small grow tents are designed for people who are either growing a small number of plants or don’t have enough space to accommodate larger dark boxes. If you want to sneak your operation into a closet or back corner, these models are made for you.
If you have a large plant capacity, you’ll want to consider grow tents that can adequately hold them. Tents in the 4×4 range and higher—like the adjustable roof on the Gorilla grow tents—may be a better fit. Other larger grow tents to consider include the Mars Hydro Grow Tent and Vivosun Grow Tent.
What to know before you buy a mini grow tent
Not everyone has the square footage to turn their spare room into an indoor greenhouse. If you’re tight on space, small grow tents are a great alternative—if you know what to look for.
Keep an eye out for models with adjustable vents, strong frames, and reflective interiors. Other features like access points, zipper quality, and light coverage can sway your decision. And because size does matter, measure your space before pressing that purchase button.
Types of micro grow tents
Most small grow tents use the same basic architecture, with a reflective interior and small vents to regulate humidity and temperature. While these mini-shelters tend to look the same, there are two variations you’ll find on the marketplace: plastic and metal build. Both offer their own advantages and disadvantages, and understanding the differences between the two can help narrow down your options.
Plastic small grow tents tend to be lightweight, cheap, and easy to move around, but they don’t provide the same amount of support as metal frames. The water-resistance material isn’t prone to rusting or corroding like metal, but if they crack, repairing them is almost impossible.
These types of tents are ideal for beginners, temporary setups, and those operating on the smaller side of small grow operations (think one to two plants).
Metal small grow tents are more expensive, but they offer a robust frame that can handle heavier loads—like lights, filters, and extra shelves for storage. Although metal is more durable and secure, it’s also prone to rust depending on the environment, so routine maintenance is necessary.
If you’ve got a lot of gardening supplies to store, or plan on expanding your small operations over time, then metal models are the way to go.
One of the challenges indoor growers face is how to fit their wide variety of plants—that require varying degrees of light and water—into the same small space. This is where grow tents with multiple chambers come in handy.
Tents are typically designed with two or three separate chambers, so you can create small ecosystems for each type of plant. These multi-chamber models provide the flexibility to experiment and learn which plants do best in your specific grow room. However, the smaller your tent, the less room you have for multiple chambers.
No matter the size, all tents need ventilation as it gives plants access to carbon dioxide and fresh air. The best small grow tents include multiple ports of different sizes that allow you to set up ventilation systems like small fans and filters. Ideally, these ports will be dual-cinching, meaning all light coming through will be blocked, so it doesn’t disrupt your plants’ photosynthesis.
Mesh vents and windows are also useful for small tents as they provide an influx of fresh air without allowing too much light to escape.
Canvas-like fabrics are the go-to material for small grow tents as they provide a reflective interior and can block out light. Cheaper models usually use polyethylene, while higher-end tents feature Mylar—a thicker material that provides better insulation and reflects more light.
As a general rule of thumb, the thicker the material, the more durable the tent. You can measure that thickness by looking at a tent’s thread count. Not all models list them, but if they do, aim for a thread count of at least 210D (denier). The higher, the better.
The advantages of owning a small grow tent
We know that grow tents, in general, provide an ideal environment for plants to thrive. You get to control every aspect of their container, from the lighting to temperature to humidity. This results in vigorous growth, larger yields, and higher-quality plants.
But small grow tents come with their own specific set of advantages, the most glaringly obvious perk being that it takes up less space, making them ideal for small properties and tight rooms. Thanks to their small size, they can fit in almost any area—even small closets—which allows for more discreet placement.
On top of that, small tents are much easier to move around and take down, meaning they’re perfect for people who need the ultimate portability. And since small grow tents help retain heat more efficiently and use less energy than larger ones, you’ll likely spend a little less on electricity bills. Growing plants and saving cash? We call that a win-win.
- They take up less space and can be stored discreetly.
- They are easy to transport and take down.
- They use less energy than large tents, which will save you money on electricity bills.
Tips for using small grow tents
Whether you’re an amateur gardener looking to spruce up your small apartment or a professional grower experimenting with different crops, small grow tents are a great solution. Before you make the plunge, you need to choose the location.
The ideal spot should fit the size of the tent you have in mind and be positioned close enough to an electrical circuit that can adequately handle the power of your equipment. Pick a place that’s on top of tile or concrete floor, as water can sometimes accumulate on the ground.
Next, you’ll need to plan out your design. What type of lights do you need? How will you ensure adequate airflow? These are all important questions to consider. And after you get your grow tent setup complete, start keeping a garden journal to record growth and monitor other environmental conditions like humidity, temperature, and light. It helps to have a record of all the factors that are influencing your small grow tent so you can adjust things as needed.
- Choose a location that’s close to an electrical outlet.
- Plan out your design and equipment before you start purchasing things.
- Keep a garden journal to record metrics and make adjustments.
Choosing small grow tents can seem overwhelming, but it doesn’t have to be. There are a few key considerations to keep in mind when picking the best small grow tent for you. From understanding the materials to finding the ideal placement, these FAQs will help make things a bit clearer.
Are indoor grow tents worth it?
Yes! Grow tents offer the perfect environment for your indoor plants to thrive and yield larger, healthier crops.
How big of a grow tent do I need for one plant?
It depends on the size of your plant. But generally, a 2′ x 2′ tent will fit up to two plants, while a 2′ x 4′ tent can accommodate up to four.

Unfortunately, no. You need to invest in an air filter or a carbon filter to keep the odors from escaping.
