Why Use The Best Indoor Grow Tents?

Think of a grow tent as an indoor greenhouse that’s powered by artificial light rather than the sun. The enclosed environment allows you to control and optimize all aspects of your growing conditions.

The Best Indoor Grow Tents Optimize Lighting

Use a grow tent and you’ll never have to wonder if a fence or tree will shade your plant. There is “sun” all day, every day in the grow tent, and you control the hours of light with a timer.

Conserve Energy

Another great feature of grow tents is the highly reflective lining. It bounces back the light that would normally spill off the side of your plants. You’re paying for electricity to power you grow lights, make the most of those photons.

Humidity Control

Because grow tents can be zipped shut, you can control humidity levels significantly. While most grow tents are not airtight, they seal fairly tightly. This captures the water evaporating from your plants and increases the humidity in the tent.

Grow Year-Round

Since the grow tent will be indoors in a temperature-controlled environment, you’ll be able to enjoy some gardening even in the winter. You could even move your favorite plants to your indoor grow tent before they succumb to a killing frost.

Reduce Pests

Pests such as grasshoppers, caterpillars, aphids and others can be a real nuisance when growing outdoors. When using an indoor grow tent, you don’t have to worry about them infesting your plants. However, you should always sterilize equipment that has been stored outdoors and start with fresh sterile soil. This eliminates the possibility of introducing pests into the garden.

Things To Consider when Choosing the Best Indoor Grow Tents


Grow tents come in a variety of sizes. The most common size tent has a 48″ x 24″ footprint. This can accommodate a lot of seed starting trays, plenty of leafy greens, or 3-4 full sized plants such as peppers or tomatoes. One of the big draws of this size tent is that it can be used in a closet.

The grow tents go up in size as well. Other common sizes are 48″x48″ and 96″x48″ grow tents. There really isn’t much limit to the size you can find if you have the space, you can even get a 10’x10′ grow tent if you’re a serious grower.


The best indoor grow tents will have large zippered openings. We prefer the type with doors that wrap the corner of the tent. This allows you to view or access the back side of plants versus only opening in the front of the tent.


When it comes to construction, the best indoors grow tents will use a thick canvas material. The way the canvas is stitched together will also contribute to the longevity of the tent.

Reflectivity of the best indoor grow tents

All grow tents on the market have a reflective Mylar lining. Reflecting light onto your plants is important and will help you get the most out of your grow lights for seed starting or when growing plants to full size. The best indoor grow tents have a rippled Mylar lining, sort of an orange peel texture, that diffuses light and prevents plants from burning.


An important feature of grow tents is the way they ventilate. There should be upper ports that can be opened to dissipate the heat from the grow lights above you. The best indoor grow tents also have mesh openings covered by a Velcro flap near the floor. High and low vents can allow passive intake of cool air through convection of warm air rising through the top vents.

Waterproof Base

It’s important that the tent incorporates some sort of waterproof base insert. The corner stitching of the main canvas structure itself will not retain spilled water. A waterproof base that is removable also allows you to clean it between grows.

How We Evaluate the Best Indoor Grow Tents

The size of the grow tent will depend on the available space of the gardener. We evaluate tents by their accessibility, durability and features such as the reflective lining and port openings. We also consider cost and any accessories included. You’ll notice that we listed the grow tents as best-in-class, everything from best value to best quality. This way we can ensure that everyone can find the best indoor grow tent to suit their needs.

Best Indoor Grow Tents: FAQ

Are indoor grow tents worth the money?

Although you’ll need to invest a little money in the grow tent, there are definitely some benefits. Reflectivity utilizes the light effectively and the enclosed environment reduces the amount of water needed and provides a more ideal humidity for plants. You’ll save time, money, and reduce frustration. On top of that, your plants will grow better.

What size grow tent for beginners?

We recommend a 48″x24″ grow tent for beginners. It can be well lit by a modest-sized light and accommodate a good number of seedlings or a couple of full-sized plants.

Do indoor grow tents need ventilation?

Fresh air entering your tent will benefit your plants. All grow tents should at least use passive ventilation and a circulator fan. If your lights generate a lot of heat, you should consider using an exhaust fan. There are many electrically powered exhaust fans made for grow tents that mechanically pull fresh air through the tent while exhausting heat.

Should I run my exhaust fan in my grow tent all the time?

You really only need to run the exhaust fans while the lights are turned on. During the dark periods there will be no heat generated from the lights and the plants will only benefit from the air exchange during the light period.

What temperature should a grow tent be?

The ideal temperature for a grow tent is between 75-85F. However, this will ultimately depend on the types of plants you’ll be growing. Raise or lower the temperature based on your plants’ needs.

Do plants grow faster in a grow tent?

Yes. There is no wasted light in a grow tent. The reflective lining bounces light that would be lost back to your plants. Grow tents also keep humidity levels up and provide a greenhouse type environment for plants. Your plants will be happier and healthier in a grow tent versus an open area with a grow light over the top of them.

How much light do I need for a 2’x4′ grow tent?

Generally speaking, you should provide at least 30 watts of lighting per square foot. Of course, some lights, such as LED’s, are more energy efficient. We recommend the Viparspectra P2000 or XS2000 for a 2’x4′ grow tent.
