What is a Grow Tent?

Grow tents, also known as “grow rooms,” are collapsible tents used to grow plants indoors. You can create an ecosystem for your indoor garden that is isolated from the rest of your indoor space using a grow tent. They are ideal for places like a garage or closet that aren’t typically good for growing.

Depending on your needs, indoor grow tents are offered in a range of sizes, specifications, and costs. The majority of grow tents have a fabric exterior that is supported by a rigid frame with a reflective silver coating on the inside to keep your plants warm and cozy. Then, for electrical access and ventilation, they frequently have various ports or openings.

Why Do People Use Grow Tents?

Grow tents are primarily used for growing high-value crops for personal consumption. Due to their diminutive size, they are not suitable for the majority of industrial or commercial applications.

Grow tents are excellent for growing a variety of plants, including leafy greens, peppers, mushrooms, wasabi, green beans, carrots, and many others, although they are most frequently used for the cultivation of high-dollar crops like marijuana.

Why Should I Spend My Money on a Grow Tent?

A grow tent is an excellent way to grow plants in the absence of direct sunlight. It also aids in growing at any time of year, and they are portable, allowing you to grow even flowers indoors during the winter, when necessary! As if that weren’t enough, they are typically inexpensive; even the larger ones frequently cost between $100 and $200 (depending on size). Considering the advantages, buying one now is worthwhile.

What Benefits Can You Get from Using Grow Tents?

Year-Round Growing

Grow tents provide a suitable environment for your indoor hydroponic/soil garden, allowing you to have fresh produce all year long.

Total Control Over The Growing Environment

Grow tents let you control the light, water, temperature, and humidity to which your plants are exposed. The indoor growing environment is now more under your control. With the help of grow tents, you can regulate the humidity, temperature, light intensity, and water for a healthier, more vigorous plant growth cycle. Given that you have control over the environment, the weather and other factors are not an issue.

Works With Other Products

To better control the environment, you can also connect the grow tents’ necessary components, such as humidifiers, heaters, lights, fans, and air conditioners (for better air circulation).

Keeps Pests Out

Since plants in a grow tent are isolated from other plants, the transmission of pests and fungi is reduced. Additionally, grow tents typically have flood-proof floors and an airtight seal to help protect from changes in outside temperature, this greatly improves pest control in comparison to open or outdoor spaces, as this seal can shield against noise and odors.

Odor Control

Some plants emit allergens and odors that you don’t want in your house. These smells will be kept out of your home and away from your family by the grow tent.

Noise Protection

Tents can also be used to keep noise at bay. For instance, you could play music to possibly encourage plant growth, but the sound would not carry throughout the house. Conversely, noises in your home won’t disturb your plants.

Energy Efficiency

The energy efficiency of grow tents is very high. They are internally coated with a reflective material that disperses the light from your sunlamp. Because the light’s rays are amplified in this way, your plants will receive the energy they require without using up a lot of the lamp’s energy. Plus, compared to a more centralized beam of light, the light is more evenly distributed throughout the grow tent using its reflective interior walls. The photosynthesis of plants is improved by this increased light concentration.

This efficiency can also help you save money. This controlled environment makes sure there are no unnecessary expenses that result in extra costs. Additionally, your chances of losing crops to weather, pests, or flooding are reduced.

Easy Accessibility

Additionally, you don’t need to construct a separate building, like a greenhouse. And you won’t have to walk through the rain to get to your garden. You can always access your grow tent so that you can take care of your plants.

How Do you Select The Best Grow Tent?

When you’re looking for a tent for your plants, there are lots of features to take into consideration. While cost and even branding can be indicators of the quality of a tent, those two things alone don’t always mean you’re getting the tent you need. Here are the factors to consider before selecting a grow tent for your plants.


The size of the grow tent you’ll need should be your first consideration:

How much space do you plan to dedicate to growing a garden? How many plants are you growing? What size are the plants that you are raising? How much height can they expect to attain? What size will they be when fully developed?

What kind of gear will you need to fit inside? How extensive is your hydroponic system (if you are using hydroponic planting mediums)? How big are your planters and pots? How large are your humidifiers, grow lights, nutrient reservoirs, ventilators, and other equipment? How much space will you need to allow for the movement of the grower inside the tent? Will maintaining the garden require you to be inside the tent?

You can probably afford to purchase a tent that only requires you to reach inside if you only intend to grow a few tiny plants that won’t get very tall. You need a tent that is much taller (6 feet or more) if you are growing a species that is more leggy and tropical and produces a much higher, fuller canopy.

You’ll be able to gauge how much space you’ll need for your plants based on their quantity and size. This will ultimately determine the potential size of your garden and the amount of produce it can produce each season.

Using the number of plants you can grow, you can quickly determine the size of your tent as follows:

  • Grow Tent 2′ x 2′ – Ideal for mother plants (1-2 plants)
  • 2′ x 4′ Grow Tent (2-4 Plants) – Fits in most closets
  • For those with a small workspace, the 3′ x 3′ grow tent (2-4 plants) is ideal.
  • A 4′ x 4′ grow tent is ideal for holding 4-6 plants and a 1000w HID or LED grow light.
  • Grow tents in the most popular sizes (4–10 plants) are 5’ x 5’ and 4’ x 8’.
  • Expect large harvests with the 5′ x 9′ and 8′ x 8′ grow tents (9–16 plants), which are ideal for a spare bedroom.
  • 10′ x 10′ Grow Tent: This size is also ideal for use in the garage or in a spare bedroom (12–18 plants).
  • Grow tents that are 8′ x 16′ and larger: 16–32 plants need a lot of space and power.


Your grow tent’s fabric or construction material may have an impact on the plants inside as well. The highest quality grow tents are constructed from sturdy canvas materials like nylon or polyester. These are strong and long-lasting, allowing you to better control the environment inside.

The “D” rating of the tent will tell you how thick the material is. 200D to 1680D are the dimensions of grow tents. The thicker the yarn, the greater the “D” rating. The Gorilla Grow Tent with 1680D Diamond Reflective Walls is one of the thickest and most durable tents available.

The composition of the inner layer is also important for plant health. The inner layer of most systems is shiny and reflective; it is frequently made of polyethylene terephthalate. The reflectiveness can be between 50 and 90 percent. The more reflective they are, the less energy you’ll waste lighting your plants, which will improve light coverage and increase cost savings.


The frame gives the grow tent its structural support and stability. To support your indoor plants and equipment, you need a sturdy frame.

Heavy-duty steel is the most durable frame, but it is also the most expensive and difficult to work with. The strongest metal poles are used in gorilla tents to provide the maximum level of safety and security without taking up too much room in your space.


Different grow tents have distinctive features, such as various port or vent types. For instance, while some tents have multiple openings, others might only have a few with double flaps or drawstring closures. These vents can be used to connect the internal systems and tools to outside electricity, ventilation, and automation equipment. Your preference for ports will be influenced by the equipment you plan to keep inside your grow tent.

How Do Grow Tents Function?

Grow tents are made up of several components, each of which plays an important role in how the tents work.

The Outer Fabric

Effective grow tents are made of heavy-duty canvas fabric that is bonded to a reflective inner layer. The fabric’s thickness is expressed in terms of density with a number such as “600D.” The most important thing to remember is that the higher the number, the stronger and denser the outer fabric.

The Inner Lining

The interior lining of a grow tent is designed to reflect light. The inner lining of a grow tent promotes better lighting for your plants while also ensuring even coverage. Choose the most reflective inner lining you can find. The more reflective the interior lining, the better the efficiency of the grow tent.

The Frame

The framework that supports the poles installed beneath the fabric provides the structure of a grow tent. The tent’s shape and stability are provided by these poles. A sturdy frame is also essential for supporting a variety of necessary tools, such as grow lights.

The Vents and Ports

Indoor growers choose growing tents to establish a regulated and enclosed environment. For reasons including ventilation, cooling, dehumidification, control, and more, your grow tent needs access to the outside.

A quality grows tent will have vents and access ports that are situated so that you can connect the required tools for setting up a completely controlled environment.

It’s important to remember that your grow tent is only the outer covering. You’ll also require a few extra pieces of equipment, which you should arrange in a way that will enable you to create a consistent and ideal environment for plant growth. The additional equipment listed below will help your grow tent function flawlessly.

Grow Lights

Grow lights provide adequate lighting to your indoor garden in the absence of natural sunlight, Make sure to base your decision on the size of your tent to avoid selecting an overly or underpowered grow light.


A ballast is necessary if you’re using a digital grow light because it controls the electricity arc inside the bulbs so they don’t blow up and makes sure they have enough voltage to start. Digital ballasts that can be customized to your lighting are available on the market.


You must have a fan in your indoor grow tent because it helps to circulate the air and keep the grow room cool by constantly blowing air above, beneath, and around your plants. Fans are usually a very efficient ventilation system.


Filters are strongly advised for controlling emissions and reducing odors. The carbon filter is the most effective.


Ducting is frequently required to connect filters to specific fans.

Temperature/Humidity Gauge & Timer

These three things are self-explanatory; you want your plants to be kept in a controlled environment at all times, so being able to monitor the temperature and humidity is invaluable to your growing cycle. Additionally, your timer is used to set the on and off times for your light. On the market, there are some gauges that perform all of these tasks simultaneously.

Heating Pads or Mats

By gently warming the root region, a heating pad can encourage faster growth and higher success rates for both seedlings and cuttings. A heating pad is a simple and efficient way to provide your plants with a little extra care during the colder months. It is ideal for use in cooler climate zones. A heating mat is an essential tool for any gardener, whether you’re trying to lengthen your growing season or you just want to give your plants a head start. Anyone can benefit from faster growth and healthier plants because it’s so simple to use.

How to Prepare Your Grow Tent For Planting

  • Research the number of plants you would like to grow and what type they are (indoor or outdoor).
  • Decide on your grow tent size based on the number of plants you will be growing and whether or not you need a ventilation system.
  • Consider how much space is available in your home, backyard, or greenhouse before deciding on tent size.
  • Choose whether or not you want to purchase an automatic venting system for your grow tent.
  • Place your grow light in the desired position inside the tent before attaching it securely to the ceiling hooks with zip ties, and make sure your tent is light-proof and light-tight.
  • Place your heating and cooling system in desired locations near the sides of the tent.
  • Take measurements from the ceiling and floor of your grow room to plan for how much space you need to place your shelves and other equipment.
  • Prepare a drip system for watering plants.
  • Securely attach hoses together with hose clamps in order to have one continuous, long run as well as one short run that can be extended when needed.
  • Attach an air pump to the long run, which should be connected to a length of tubing.
  • Attach a water valve to the short run, which should be attached to a length of tubing.
  • Prepare your growing medium, either soil or hydroponics. , and transfer your plants to the growing medium.
  • Adjust the intensity of your lights to suit the current requirements of the plant’s stage of growth.
  • Use a humidity tray if you want to maintain higher levels of humidity in the air.

Always remember to give your plants some TLC (tender loving care), and you’ll be able to watch your plants grow and mature into a lovely harvest.

Which Brand of Grow Tent is The Best?

Beginner growers frequently struggle to choose the appropriate materials and equipment for their setup due to the overwhelming number of options available to them.

Furthermore, most beginners do not have much money to invest in high-end equipment. If this describes you, don’t worry; we’ve listed a few grow tent recommendations below.

The best grow tents for the money are made by Covert. Covert Grow Tents, the best value grow tent on the market, provides everything you require and nothing extra. Look no further than Covert if you are just starting out or want to start growing indoors without breaking the bank.

The Gorilla Grow Tent is another popular option. The name comes from the fact that these tents are the toughest in the business. They are very expensive, which discourages novice growers, but they are very well-liked by more seasoned growers who can devote more resources to their gardens.

Another excellent choice is Secret Jardin, as these grow tents are distinguished by their multi-chamber appearance and offer a distinctive look.

For newcomers, making the decision to have their own grow room can be exciting. It enables them to grow crops, vegetables, fruits, and so on in the comfort of their own homes, particularly with the assistance of indoor grow lights.

Essential Grow Tent Buying Tips

Here is one last piece of advice on what to look out for when buying your tent in order to get a high-quality item that will perform and last you for many cycles to come. Now that you are feeling more knowledgeable, you are aware of what you are growing, and you know what size tent you need.

High-Quality Stitching and Seams

One of the most crucial characteristics of a good grow tent is that it should be a “semi-sealed” environment that does not permit the entry or exit of heat, light, or pests. This is dependent on how the tent is made, so make sure there are no weak spots and that seams and stitching are tight and sturdy.

Quality Zippers and Fasteners

You should make sure the zips are sturdy and securely fastened for the same reasons as stated above. If the zip breaks, your tent won’t operate at its best because it won’t be able to maintain its light-tight, sealed environment. Even a tiny, insignificant-looking zip that bursts or simply comes loose from the tent fabric can be harmful. Over time, the fabric may shift, creating stress points and damage in other places. It may also make the tent’s overall fit lose, which may affect the atmosphere and pressure inside the tent when the ventilation is on.

Strong and Rigid Tent Frame

Verify the strength of the poles’ construction by looking for any obvious damage or weaknesses in the metal.

Solid Corner Brackets

In keeping with what was said above, the corner brackets are what hold your entire frame together. As a result, they must once again be well-made, and sturdy, and hold the poles together securely with little movement in the frame when assembled.

Appropriate Exterior Fabric

The tent cover should be made of a durable fabric with a canvas-like texture, typically from nylon, polyester, Mylar, or a combination of materials. A strong fabric will prevent pests from entering, lessen noise, and prevent odors from escaping while still maintaining your environment’s lightproof, heat-retaining, watertight qualities.

Interior Reflective Lining

The entire interior surface of the tent, including the walls, floor, and ceiling, should be covered by this. Silver or white are both acceptable colors for the reflective lining. Both are effective, but due to their greater ability to retain heat, silver tents can be up to 1-2°C warmer than white ones. There are two popular designs for silver-lined tents: lychee and diamond.

Ample Ports and Vents

The number of ports and vents on a good tent will provide you with a wide range of secure positioning options for all of your equipment and electrical cables. Additionally, ports and vents need to have effective ways of opening and closing that always maintain the sealed environment of the tent.

Complete Compatibility

In order to ensure compatibility, keep in mind that the size of your tent will directly affect the other pieces of equipment you need, such as the number of lights and the power of an extraction kit. Another reason why a complete tent kit might be the best choice when first starting out is. You can rest easy knowing that everything you have is ideal for the size of your setting in this way.

What Makes Grow Tents So Popular?

Here are a few factors that contribute to the popularity of grow tents over indoor grow rooms and outdoor growing areas:

  • Energy efficient
  • Low running costs
  • Lightweight
  • Mobility and Accessibility
  • Ultra-Thick Fabric to shield plants
  • More Control
  • Plastic-Free
  • Pest proof
  • Noise proof
  • Odor-free
  • Vents

Do Grow Tents Make Sense Financially?

Nowadays, with excessive heat being a problem in many parts of the world, being able to shield your plants from the scorching sun and extreme heat can mean the difference between growing a successful home garden and wasting your time, money, and resources without any results.

You’ll end up spending less money overall, even though your grow tent may require a sizable initial investment. This is due to the fact that a grow tent makes it less expensive to supply your plants with water, nutrients, and light.

Because they give you complete control over the environment and are simple to set up, grow tents are the best way to grow marijuana. They give you control over a variety of variables, including temperature, humidity, and CO2 levels. Grow tents are the way to go if you want to start an indoor grow or if you are an experienced gardener looking to try something new.
