9 Best Small Grow Tents and Mini Tens for Indoor Gardening

A small grow tent, also known as a mini grow tent, is a compact and enclosed space used for indoor gardening. These tents are smaller than standard grow tents, typically measuring less than 2×2 feet.

A small grow tent includes advantages such as portability and space efficiency, while disadvantages include limited capacity and difficulty maintaining consistent environmental conditions. Small grow tents are suitable for various cultivation methods and plants, such as shallow-rooted plants like microgreens or herbs. Still, they are inappropriate for larger plants with extensive root systems, like tomato plants.

When choosing a small grow tent, key points include material quality, ventilation, and reflective walls.

The setup and use of a mini grow tent differ from a normal-sized grow tent, primarily in scale. The ventilation system, grow lights, and other equipment used in a small grow tent will be smaller and less powerful than those used in larger tents. It’s important to choose appropriate equipment that fits the size of the tent to ensure optimal plant growth and prevent any potential issues, such as overheating.

How Do You Choose the Best Small Grow Tent for a Compact Space?

When choosing the best small grow tent for a compact space, consider growing space size, the frame structure of the tent, ventilation, and material.

• Growing Space Size: refers to the area or dimensions where you plan to set up your grow tent. Choosing a small grow tent that fits within the designated space is important to avoid overcrowding and ensure optimal plant growth. For instance, tomatoes generally need around 2 square feet per plant, while for cannabis plants, the space required per mature plant typically ranges from 2 square feet to 4 square feet.
• Frame Structure: The frame structure of a grow tent refers to the material used to construct its frame, which can be either plastic or metal. Metal frames, such as steel, provide better stability and durability than plastic frames. A small grow tent should be able to support equipment that weighs up to 50-100 pounds (22-45 kilograms) without any issues.
• Ventilation: Ventilation in a grow tent refers to the airflow and air exchange within the enclosed space. Good ventilation is crucial for controlling temperature/humidity and removing stale air. Look for mini grow tents with vents, ducting ports, and mesh windows to facilitate proper air circulation and prevent issues like heat buildup and excess moisture.
• Material: Evaluate the tent’s material, as it can affect light reflection and durability. Common materials used for grow tents include canvas-like fabrics, polyethylene, and Mylar. Canvas-like fabrics provide good light blocking, while polyethylene is lightweight and easy to clean. Mylar has excellent light-reflective properties, maximizing the efficiency of your grow lights.

What is the Smallest Grow Tent?

The smallest grow tent is the Hydro Crunch tent. This mini grow tent measures 16x16x48 inches. It can typically accommodate 1-2 mature tomato plants, a handful of herb plants, or a single cannabis plant, depending on the specific farming method and plant size.

Also, the Secret Jardin Hydro Shoot, in its larger size, typically measures 48 inches in length, 24 inches in width, and 60 inches in height. This configuration results in a volume of approximately 69.12 cubic feet.

How Do You Heat a Small Grow Tent?

To heat a small grow tent effectively, consider using a specialized electric grow tent heater, improving air circulation with fans, and employing heat mats for root warmth.

Warming a small or mini grow tent differs from a standard or large tent primarily due to the smaller space. Electric heaters for tents are designed to provide consistent and controlled heat to create an optimal environment for plant growth.

Additionally, improving air circulation within the tent is important for distributing the heat generated by grow lights. You can achieve this by using oscillating or inline fans to move the air around.

Another option is using heat mats placed underneath the plant containers to provide localized warmth to the roots. This can promote healthy root development and overall plant growth. 

What is the Best Heater for a Small Grow Tent?

The best heater for a small grow tent is the VIVOSUN Portable Greenhouse Heater. Two of the key reasons why this heater is often regarded as the best option are its versatility and efficiency.

The VIVOSUN Portable Greenhouse Heater offers adjustable temperature control with three heating modes: high-heat, low-heat, and fan-only mode, allowing you to set the desired temperature range for your plants. This level of control ensures that you can create and maintain an optimal growing environment.

The heater also incorporates important safety features, including overheat protection and dust filters.

How Do I Cool My Small Grow Tent?

To cool your small grow tent, you can employ three common methods: an exhaust fan and ventilation system, air conditioning, and reflective insulation.

The first method involves using an exhaust fan and a ventilation system, which are well-suited for small grow tents due to their efficient air circulation and smaller spaces generally requiring less powerful fans. 

Additionally, small portable air conditioners or mini-split systems are a suitable option for small grow tents, offering precise temperature control and effective cooling within the limited confines of the space. Reflective insulation, like Mylar, plays a crucial role in managing heat and light in smaller grow tents, bouncing heat and light back onto the plants while preventing excessive heat buildup.

How Do You Increase Humidity in a Small Grow Tent?

Use a water tray in your mini grow tent to increase humidity in a small grow tent. Place a shallow tray filled with water inside the tent. This method is particularly well-suited for small grow tents due to their limited space, which allows for a more efficient impact on the water tray. In standard-size grow tents, larger volumes of air can dilute the effects of a water tray, making it less effective for maintaining optimal humidity levels.

As the water evaporates, it will add moisture to the air, increasing humidity levels. This method is simple, low-cost, and requires no additional equipment. Remember to monitor the humidity levels regularly and refill the tray to maintain the desired humidity level.

What is the Best Humidifier for a Small Grow Tent?

The best humidifiers for small grow tents are the LEVOIT Humidifier and the LEVOIT OasisMist Smart Cool and Warm Mist Humidifier. The LEVOIT model measures 8.5 x 6.7 x 10.2 inches (21.6 x 17 x 25.9 cm), while the Warm Mist humidifier measures 10.5 x 7 x 11.3 inches (26.7 x 17.8 x 28.7 cm). These humidifiers provide cool and warm mist options, making them versatile for different plant needs. They also have essential oil boxes and remote controls for convenient use.

Can I Put a Grow Tent in My Basement?

Yes, you can put a grow tent in the basement. However, there are a few considerations to keep in mind. 

Firstly, basements often have higher humidity levels, so monitoring and regulating humidity within the grow tent is important to prevent mold and mildew. Additionally, proper airflow is crucial, so having fans and ventilation systems in place will ensure good air circulation. 

Since basements tend to be cooler, especially during colder months, you may need additional heating equipment to maintain optimal temperatures.

Lastly, it’s advisable to have a concrete floor with drains to manage water drainage, particularly if you’ll be watering your plants in the grow tent.

What Size Grow Tent for One Plant?

A commonly recommended tent size for growing a single plant is a 2’x2′ or 3’x3′ grow tent. These sizes offer adequate space for the plant and essential equipment like grow lights, ventilation systems, and other accessories. Going smaller, with non-standard sizes, can severely limit the installation of necessary devices, potentially hindering the plant’s growth. It also allows for easy access and maintenance. Ultimately, the size of the grow tent should be selected based on the specific requirements of the plant and the available space in your setup.

Will a Mini Greenhouse Protect From Frost?

Yes, a mini greenhouse can protect plants from frost. Mini greenhouses are designed to create a controlled environment that shields plants from the cold temperatures and harsh winter elements. 

The structure of the greenhouse traps heat and provides insulation, preventing frost damage to plants. Plastic greenhouses, in particular, are often used for frost protection. 

Additionally, using horticultural fleece along with a plastic greenhouse can further enhance the level of frost protection. It is important to note that while a greenhouse offers protection against frost, it may not be able to guard plants if outside temperatures drop significantly below freezing completely.

In such situations, an alternative method to protect plants is using additional insulation methods such as frost cloths or row covers. These light and breathable materials provide an extra layer of protection against severe cold and frost, helping to safeguard plants during adverse weather conditions.
