The best grow tents for weed allow you to create the ideal conditions for your plants while also conserving energy on lighting and climate control.

This article will discuss a variety of considerations you may have when choosing a grow tent, such as size, material, frame weight capacity, and more. Next, we will compare and contrast six different brands of quality grow tents to find the perfect tent for your next grow.

Why Use a Grow Tent for Growing Weed

Although the setup cost of a grow tent may seem intimidating, grow tents have many benefits that make them a superior choice to growing in a closet, cupboard, or open room.

Grow tents give you an impressive amount of control over your cannabis plant’s environment, allowing you to regulate the temperature, humidity, lighting, and even CO2 concentration with far greater accuracy than other growing methods. In the ideal climate of a grow tent, cannabis plants will grow larger and faster, and they will produce larger, more potent harvests.

Grow tents are also a more energy efficient way to grow cannabis. The reflective inner walls of a grow tent increase the efficiency of your grow lights, while the airtight walls keep heat and humidity from dissipating into the rest of your home.

Finally, grow tents provide helpful features such as support beams to mount equipment and ports to run ducts and cables through. In an open room or closet, it can be much more difficult to mount items like lights and fans, and they will often be more difficult to adjust.

What to Consider When Choosing a Grow Tent

There are a large number of different grow tent configurations available on the market, which can make selecting the perfect tent difficult. A few important things to keep in mind when looking over grow tents are how many plants you want to grow, how large a space you have to set up your tent, how discreet your tent needs to be, and how much money you have to spend on the tent and equipment. Below, you will find a few grow tent attributes that you may want to consider before making a purchase.


Common sizes of grow tent include 2×2, 3×3, 4×4, 4×8, 6×6 and more. An adult cannabis plant will take up approximately four square feet, so a 4×4 tent with 16 square feet of floor space can fit about 4 adult plants, or a larger number of juvenile plants.

Most grow tents will have a standard height of around 80 inches (6.6 feet). While this is taller than most cannabis plants will grow indoors, the top two feet or so of the tent will be taken up by lights and fans, so the usable space for the cannabis to grow is usually closer to 5 feet.


Most quality grow tents will be lined on the inside with mylar. This highly reflective material allows light rays to be bounced back at your plants, increasing the efficiency of your grow lights. Mylar is offered in a few different finishes, such as hammered and diamond. Diamond finish will reflect back more light, but it will also increase the heat in your tent more rapidly.

The outside of a grow tent is typically made of a plastic tarp, usually nylon or polyester. These materials are flexible, lightfast, and resistant to tears. 

The thickness of a grow tent’s outer canvas will be listed as a “D” rating. Grow tents can range from 200D to 1500D+, with higher numbers indicating a thicker, sturdier fabric. 

Frame Weight Capacity

Most Grow tent frames are made of interlocking hollow steel tubes which are designed to both support the fabric shell and provide places to hang equipment such as lights, ducts, and fans. The higher the listed weight capacity, the more items can be safely hung from the frame.

Except for very small tents such as 2×2, you will want a frame that can hold at least 100 lbs. Fixtures for grow lights can get surprisingly heavy, and if you mount more weight than the tent can support, you risk the structure collapsing onto your plants.

Doors and Windows

Most grow tents will have zippered doors to access the inside of the tent. Since the door is one of the most common spots for air leaks, be sure to select a tent that has quality zippers that pull up and down easily. For larger tents, try to select a model with a zipper on the inside as well as the outside, as this will allow you to close the door behind you while you are inside.

Some grow tents may also have clear plastic windows. These can be a convenient way to look in on your plants without opening the door and disturbing their air. However, some grow tents designed for plants other than cannabis may have excessively large windows that decrease the efficiency of your grow bulbs by allowing light to escape.

Ventilation and Cord Ports

All grow tents will have some configuration of ventilation and cord ports. Typically, a tent will have round ports in the top and bottom corners to run ducting and cords out of, as well as longer, narrower vents in the bottom to allow for passive air intake. 

Many tents will have features that allow the unused ports to be closed off, such as cords that can be pulled taut to close the port. These cords can also be used to get a tighter seal around ducts or other electrical cords you are running out of the tent.


A wide variety of extra features can be added onto a grow tent to accommodate more specific needs. These include two chambered tents, height extenders, shelving units, flood trays, trellis netting, and various other modifications that can make growing cannabis easier and more streamlined.

What is a Perpetual Grow Tent?

A perpetual grow tent is a system designed for continual cannabis production. This can be achieved by using two separate tents in the same room, or by using a multi chambered grow tent. Vegetative plants will be kept in one tent/chamber, and flowering plants will be kept in the other. 

Because vegetative and flowering plants have different light and humidity requirements, the two types must be kept in separate tents with independently controlled humidity, temperature, and lighting schedules. While multi-chambered grow tents are larger and more expensive, the ability to grow both life stages of cannabis plants at the same time will dramatically reduce your time between harvests.

Before moving on to this list, you may find it helpful to determine your budget and size constraints, as well as any other specific parameters a tent needs to meet.
