How much space does one plant need? Each requires at least two to three square feet to ensure that the branches spread out properly to maximize airflow between the foliage. Today, we will focus on what’s the best size grow tent for 4 plants.

“What Size Grow Tent for 4 Plants?”: Grow Tent Size Guide

How Much Room Do You Need for 4 Plants?

It’s important to distinguish the difference between small and large plants. A crop that can achieve a diameter of one meter through SCROG net training is identified as a large plant. Small plants have horizontal growth spanning up to 500 centimeters or less.

The answer mainly depends on three variables explained below.

The Type of Strain

As mentioned earlier, autoflower strains exhibit low vertical growth compared to photoperiod varieties. These branches develop into moderate bushes and this makes it possible to cultivate four untrained plants within a 0.36 m²  grow tent.

Sativa strains require tall tents to accommodate conspicuous vertical growth. Experts recommend grow tents reaching over six feet with an area of (48 X 48 inches) as sufficient for 4 plants.

Medium Used for Growth

A cultivator who wants to nurture their crops inside a hydroponics system requires a grow tent that occupies an area measuring (48 X 48 inches). This space is necessary to accommodate the grow tray and reservoir tank. The grower will also have some space to apply LST on each plant.

Cannabis grown in soil has less spatial requirements and it’s possible to nurture four untrained small plants within a 0.36 m² or (24 X 24 X 48 inches) confinement.

Application Of LST

Low-Stress Training (LST) stimulates the growth of extra branches to maximize yield production. A cultivator who wants 4 large plants needs to purchase a grow tent that covers an area of 1.4 m² or (48 X 48 X 80 inches).  The cannabis crops will have sufficient room to expand horizontally without the foliage hampering air currents from the inlet fans.

How Many Plants Can I Grow In a 4×4 tent?

A 4×4 tent is spacious enough to accommodate up to 12 small plants when cultivating using 3-gallon fabric pots. This setup, however, is unsuitable since it takes plenty of effort to inspect or water crops located at the back row of the grow tent plus corners. A grower might take a while to notice the presence of unwanted male plants since the confinement hinders daily inspections.

Maintaining a maximum of 6 small plants is advisable to provide adequate airflow between the foliage. It also provides enough space to inspect each plant daily while watering and also makes cleaning the grow tent easier.

How Many Plants Can You Fit In a 3×3 Grow Tent?

A grower can fit four small plants inside a 3×3 grow tent and use a trellis net to maximize yields through LST. The plants, however, have to grow inside a confined space. A dehumidifier is necessary from germination to harvest to prevent moisture accumulation and mold infestation.

Yields tend to be unimpressive when plants are tightly squeezed in a confined space. Buds tend to grow smaller in size and it becomes difficult to hit the one-gram-per-watt target. The best option would be to grow two plants to maximize their full potential and harvest better yields.

How Many Plants Can You Fit In a 2×2 Grow Tent?

The best way to maximize space in this setup is using 3-gallon grow pots. A 2×2 grow tent can safely accommodate three small plants plus room for a trellis net. Cultivators who prefer this indoor setup need dehumidifiers and good inlet fans to prevent excess humidity.

Extra Things to Consider When Choosing A Grow Tent Size

1. Adequate Ventilation

One of the disadvantages of overcrowding crops is the accumulation of excess humidity. Fortunately, some manufacturers produce grow tents that have two or more intake vents to promote adequate airflow between the foliage. They also contain ducting ports for two outlet fans for enhanced odor and temperature regulation.

2. Accessibility Through Side Doors

A good grow tent should have three side doors to allow the cultivator to inspect and water each plant conveniently. Some grow tents contain zippers on each wall that open and close from the outside to prevent the need for taking plants out one by one.

3. Sturdiness Of The Supporting Poles

A grow tent containing more than six plants requires several inlet and outlet fans to sustain adequate airflow. The plants also get heavier as the buds mature. It’s crucial to have a reliable grow tent with sturdy poles that can support the equipment plus the weight exerted on the trellis net by flowering crops.

Is It Better To Grow A Few Large Plants or Many Small Ones?

Advantages of Cultivating Fewer Large Plants

1. Cost-Effective Strategy

It’s easy to maximize the amount of indoor light each plant receives by simply reducing the population inside a grow room. The cultivator only needs to purchase an affordable grow light for $500 to sustain the cannabis crop from germination to harvest. This strategy ensures that the fan leaves and bud sites receive sufficient light for photosynthesis to maximize yields.

A cultivator that’s nurturing 10 crops needs an extra hand to inspect, defoliate, and train the crops. It’s quite time-consuming to carry out top to bottom inspections on each plant every day. In addition to labor costs, the grower may need to purchase two or three grow tents to create space for the crops. Each grow tent requires its own set of equipment such as carbon filters, dehumidifiers, and fans resulting in expensive overhead costs.

2. Best Strategy For Maximizing Each Plant’s Potential Yields

Low-Stress Training (LST) enables plants to maximize the growth of bud sites during flowering. A setup containing 4 plants allows the cultivator to stretch the branches across a large area when using a trellis or SCROG nets. Growing fewer large plants tremendously increases your chances of achieving the one-gram-per-watt target recommended for indoor cannabis growing.

A growing space containing more than 6 plants can only handle a minimum LST. As the canopies thicken, it becomes harder to circulate air effectively inside the confined space. The humidity trapped under the canopies can lead to mold infestation and bud rot.

3. Drying The Yield Is An Easy Process

After chopping down the plants and doing a wet trim, the buds will dry in a controlled environment for 7-10 days. A cultivator with a few large plants can use the same grow tent as a drying room by hanging entire plants upside down. The next step is getting a simple air conditioner unit and dehumidifier to sustain the desired environment for drying.

While growing several plants generally yields higher yields, the cultivator needs a huge space to dry the harvest within optimum parameters. Growers who cannot access an extra room face a high probability of encountering mold infestation as a result of poor airflow inside the drying room.

4. Easier Maintenance

A grow tent needs cleaning and disinfection every week. This process requires taking out the plants from the tent and then disinfecting the walls from top to bottom. The grower also vacuums the floor to eradicate any parasite eggs. It’s much easier for an individual to carry out this process by themself when they only have four plants in the tent.

A grower that’s handling three or more grow tents spends more effort carrying out weekly maintenance. This is tedious since not all cultivators can afford to hire an employee.

Advantages Of Growing More Smaller Plants

1. Seasoned Growers Can Harvest Large Quantities

Cultivators who’ve accumulated knowledge based on successfully growing cannabis consistently have a high chance of enjoying bumper harvests. It also brings a higher return on investment since a seasoned grower knows a few tips on how to cultivate several plants successfully without having to purchase extra grow lights.

2. Endless Supply of Superior Clones

A cultivator with 6 or more strains can easily create an endless supply of clones for future use. It’s less costly to nurture the clones into mature plants compared to germinating seeds after every harvest. The biggest benefit is the ability to maintain consistent yields since the cultivator can create clones from the highest yielders from each variety.

3. Reduces The Impact Of Pest Attacks and Over Watering

Growing several plants provides the cultivator with a cushion to absorb losses that occur during cultivation. A grower who’s nurturing 8-10 crops can still enjoy large harvests in case two or three plants succumb to severe pest attacks or overwatering. The same loss, on the other hand, would be devastating to a cultivator who’s growing less than five plants.


The best size grow tent for 4 plants cultivated without any LST is (24 x 24 x48 inches). It’s an affordable setup for first-time growers and facilitates daily inspection for each plant. Seasoned cannabis cultivators, on the other hand, can maximize each plant’s potential by growing the 4 plants inside a 4 x 4 tent.
