What Is a Grow Tent? [A Complete Guide]

Not everyone has the space to create a garden outdoors — and gardening indoors is definitely not the easiest thing to do.

For budding home growers, grow tents is a great solution. They are not only convenient, but they also allow you to regulate growing conditions.

Before purchasing a tent, you also need to consider some important factors.

So, in this article, you’ll find out everything you need to know about grow tents.

What Is a Grow Tent?

Grow Tent

A grow tent or a grow room is a tall, compact fabric box lined with reflective interior walls to grow plants indoors year-round.

The outer lining is typically made from heavy-duty fabric like nylon or polyester. It’s held up by metal poles slotted together to make a strong frame.

The inner lining is often made from Mylar, which is designed to be extremely reflective to maximize light exposure of the plants inside.

Grow rooms are available in various sizes, features, and prices.

They allow you to control different aspects of the plant environment inside the compact tent. It’s equipped with several openings and other equipment, such as:

  • Circulation and exhaust fans
  • Grow lights, metal halide, and sodium vapor lamps
  • Heaters
  • Humidifiers
  • Air conditioners

Using a grow tent allows you to control temperature and humidity levels to get the desired results.

What Are Grow Tents Used For?

Because the space of a tent is limited, it’s mainly used for cultivating high-dollar crops for personal use.

Due to their limited capacity, these tents are NOT suited for industrial or commercial purposes.

Grow tents are normally used to cultivate marijuana — however, they’re also used to grow vegetation, such as:

  • Mushrooms
  • Peppers
  • Green beans
  • Carrots
  • Leafy greens

With indoor grow tents, you can make plants grow faster, taller, or bear bigger fruits within a controlled environment.

You are essentially creating an artificial climate that would be impossible to replicate in an outside environment.

A grow tent helps grow different plants that may not grow natively in your specific locality.

You can control and maintain a grow tent’s ventilation and light conditions to the desired levels to support the different stages of the growth cycle.

How Do Grow Tents Work?

A grow tent is a controlled environment containing various equipment that can regulate lights, temperature, and humidity.

A good grow tent has electrical access to lights and a ventilation system for temperature control.

See the following components of a grow room and how it works to efficiently produce plants:

Light Conditions

Plants NEED light to power their growth.

Grow tents use high-powered grow lights to mimic natural sunlight. To help, the silver inner lining ensures maximum light reflectivity to the plants.

ALL parts of the plant are exposed to light, compared to natural environments where the lower parts are often in the shadows.

The light-proof or “light tight” feature of grow tents also keeps light from coming in or out. This ensures minimal light leakage.

It’s effective for growers who want to simulate the 24-hour light cycle necessary for plants to grow.

Your plants receive light (and darkness) when you want them to.


Due to the enclosed structure of a grow tent, it provides great insulative properties to retain heat.

Unlike the unpredictability of external temperature changes, you can directly regulate the temperature according to your plants’ needs.

Alongside the glow lamps, the ventilation system manages the temperature and air circulation within the grow tent.

A grow tent has several ports that give access to the necessary equipment to control cooling, humidity, ventilation, and more.

Regardless of the external temperature, a grow tent creates a stable environment that can let your greens grow as efficiently as possible.


The combination of light and temperature conditions determines the humidity levels in a grow tent.

Humidity is an important aspect that directly impacts a plant’s transpiration rate.

Transpiration refers to the evaporation of water from a plant’s surface. It also assists in driving water and nutrients to various parts of the plant.

It’s a MAJOR component in guaranteeing plant health.

High humidity levels in a grow tent can result in molding and rotting, which can ruin your yield.

TIP: It’s important to clean the tent regularly to ensure healthy cultivation. This also prevents bacteria and fungi from growing.

Using a thermometer and hygrometer, you can closely monitor the lighting and temperature for a balanced humidity.

The contained environment of a grow tent means that your plants’ growth remains unaffected by outdoor weather changes and other factors.

What Are the Benefits of Using Grow Tents?

Grow Tents

Whether you’re tending to mother plants or growing clones, grow tents have much to offer when it comes to indoor gardening.

Let’s look at the benefits of grow tents over other growing options:

1) Improves Photosynthesis

Grow rooms have “light-proof” Mylar interior lining that reflects light at every angle and prevents light leakage.

In an outdoor garden, insufficient sunlight often causes yellowing leaves in shadowed parts of the plant.

With a grow tent, you control the intensity and exposure of lights that your indoor cultivation receives.

Because of the reflective interior walls, ALL your plants receive plenty of lighting from the grow light.

2) Gives You Environmental Control

A grow tent gives you COMPLETE control of your plants’ growing environment.

Using lights, humidifiers, and different equipment, you can regulate and maintain the light, water, humidity, and temperature your plants receive.

You don’t have to worry about rain or excessive heat that can affect the growth of your plants.

Grow tents have flood-proof floors and sealed ports to help keep out pests and protect against potential flooding.

It’s an artificial garden where you can create the ideal growing conditions for any plant you want to grow.

3) Energy Efficient

Grow tents are built to maximize energy efficiency.

The Mylar interior walls reflect and amplify light without requiring excessive energy from the grow lamp.

Light is diffused throughout the grow tent instead of a centralized source.

As a result, it helps speed up photosynthesis for your plants.

4) Saves Money

The energy efficiency of a grow tent means you can also cut back on costs.

Due to its smaller size, a grow tent is less expensive than setting up a large growing environment in a whole room.

A grow tent also reduces the risk of losing crops due to pests, flooding, and weather changes.

The controlled environment means no excess expenses for pesticides and garden maintenance, so you save money in the long run.

5) Controls Odor

Not only do grow tents prevent things from coming in, but it also keeps things from going out.

The airtight seals of a grow tent confine unwanted odor from seeping outside.

Certain plants produce allergens and scents that can affect indoor air quality. A grow tent prevents odors from diffusing into your home.

Grow tents are also beneficial for growers who plan to use chemicals or fertilizers for their indoor garden.

Factors to Consider When Choosing the Right Grow Tent

Grow Tent

From the temperature to the humidity, grow tents help create the best growing conditions for any plant.

Finding the perfect grow tent will depend on several factors, such as the number of plants you want to grow and the available space you have.

Here are tent-buying tips you should consider before purchasing a grow tent:

1) Space

For people living in cities or urban areas, finding adequate space for a grow tent may be challenging.

Fortunately, you don’t need an entire room to create an indoor garden.

You need to consider how much space you have at home and find the right grow tent kit.

“Shorty” tabletop tents are small enough to fit in the corner of a room. These are ideal for growers who want to clone seeds or start with small plants.

Free-standing grow tents also require more overhead and ground space, such as in an empty closet or garage.

Additionally, you must consider how many plants you want to fit inside to get the right size tent.

2) Material

High-quality grow tents are made from heavy-duty fabric, such as nylon or polyester, bonded to a reflective inner lining.

The thickness of the fabric is measured based on density (D).

The higher the number, the stronger the fabric is. Grow tents typically have ratings ranging from 200D to 1680D.

The perfect grow tent should have a durable fabric to maintain optimal growing conditions.

Among the best-selling tents on the market is the Gorilla Grow Tent with 1680D reflective walls.

The interior walls of a grow tent are made from Mylar or polyethylene terephthalate, which has 50% to 90% reflective capacity.

Get a grow tent with maximum reflectivity for better light coverage and less energy expenditure.

3) Features

Grow tent kits require different equipment to operate, which can differ depending on the product.

To ensure the best indoor growing conditions, grow tents should have a grow light, ventilation fans, dehumidifiers, and other components.

A good grow tent should have a rigid frame and access ports to support the accessories you want to add.

Frames will be exposed to extreme temperatures constantly, so they should be strong enough to withstand the pressure.

Some of the sturdiest grow tents have frames made of steel.

Ports are primarily used to connect equipment (such as ventilation and electricity) to the grow tent. Certain grow tents can have multiple openings, while others may only have a double flap.

The kind of access ports you need depends on the equipment you intend to use.

4) Plant Species

The type of grow tent you should purchase should be able to accommodate the plants you want to cultivate.

If you want to grow small plants, a short grow tent where you can reach inside should be enough.

For tall plant species, you would want a grow tent that can fit the plants AND the necessary equipment inside.

You also have to account for how tall and how many plants you want to place inside the grow tent.

Depending on the plant species, you can expect some monster plants to take up space.

5) Budget

Not only are grow tents energy efficient, but they’re also relatively affordable. You can find many all-purpose grow tents for under $400.

A budget-friendly grow tent can go as low as $90. Meanwhile, mid-range grow tents with variable heights cost upwards of $200 on average.

At the other end of the spectrum, high-quality, heavy-duty grow tents can cost anywhere between $400 to $1,000.

Expensive grow tents offer innovative features and ample growing space, but there are great value buys for half the price.That said, a well-built grow tent with solid performance means sparing expense for top-quality products.

Frequently Asked Questions

Grow tents are certainly convenient to have. Below are more related questions that people frequently ask about grow tents:

How Many Plants Can Fit Inside a Grow Tent?

The number of plants a tent can hold depends on the kind of plant you’re growing and the size of the pots.

Plants should be given enough space to grow, so it’s not recommended to use small pots to fit more in a single tent.

You can fit more pots with small greens than large or fruit-bearing plants.

Plant species that grow laterally should be placed at least 2 inches apart.

Should I Get a Multi-Chamber Grow Tent or Multiple Grow Tents?

Many growers like to have separate spaces for vegetative and flowering phases.

Some tents are even designed with multiple chambers within a single tent for this purpose. They help keep your indoor cultivation organized but may have limited interior space.

Multiple tents are preferred for growing larger greens and producing bigger yields.


A grow tent gives you maximum control over the growing environment.

It has various equipment like grow lamps, humidifiers, and ventilation fans that ensure maximum yield.

Before buying a grow tent, it’s important to consider your budget, available space, and the plant species you plan to grow.
