Are you looking to start growing cannabis indoors? Many options are available when choosing between indoor growing systems, and it can be tough to know which one is right for you. 

Here, we'll go over some factors you should consider when choosing the best indoor cannabis growing system and cover the differences between the best indoor garden systems.

Factors to Consider When Choosing an Indoor Cannabis Growing System


You'll want to choose a compact and efficient system if you have a small grow room or closet. This could mean opting for a hydroponic system or a soil-based system with a smaller footprint. 

On the other hand, if you have a larger grow room or basement, you can go with a larger, more complex system that can accommodate more plants.


Indoor gardening systems can range in price from a few hundred dollars to several thousand, so deciding how much you're willing to spend is essential. 

Remember that more expensive systems often come with additional features and may be of higher quality, but that doesn't necessarily mean they are the best choice for everyone. 


Another factor to consider is the amount of time and effort you're willing to put into your grow.

Some systems require more maintenance and attention than others, so if you're short on time or don't want to spend much time tending to your plants, you may choose a more low-maintenance system. 

On the other hand, if you enjoy the process of growing and are willing to put in the extra effort, a more complex system may be a good fit for you. 


If you're new to growing cannabis, it's generally best to start with a simpler system that is easier to manage. Soil is a good option for beginners because it is readily available and easy to work with. It also provides a natural growing environment for the plants, benefiting those just starting.

Hydroponics is another option for indoor growing, but it can be more complex and requires more equipment. 

In a hydroponic system, plants are grown in a nutrient-rich water solution rather than soil. This allows for precise control over the plant's growing conditions but requires more maintenance and attention. It's generally best for those with experience growing cannabis or other plants.

Plant Genetics

Consider the type of cannabis you want to grow. Different strains have different requirements regarding temperature, humidity, and other growing conditions, so choosing a system that can provide the right environment for your plants is essential.

Overall, there are many factors to consider when choosing the best indoor cannabis growing system. By taking the time to think about your needs and priorities, you can find the best system for you and your plants.

Types of Indoor Cannabis Growing Systems


A soil-based growing system is a type of indoor cannabis growing method that involves using soil as the primary growing medium for plants. This system is popular among indoor cannabis growers because it is a relatively inexpensive and straightforward way to grow cannabis plants.

In a soil-based system, the plants are grown in pots or containers filled with soil and nutrients. The soil provides the plants with the necessary structure and support, while the nutrients help the indoor plants to grow and thrive. 

Some growers may add additional amendments to the soil, such as compost or perlite, to improve the structure and drainage of the soil. 

Overall, a soil-based growing system is a reliable and effective way to grow cannabis plants indoors and is suitable for novice and experienced growers.


hydroponic growing system is a method of growing plants without soil. Instead, the plants are grown in a water-based solution enriched with nutrients. This method allows for precise control over the growing conditions and can result in faster growth and higher yields than traditional soil-based growing. 

Hydroponic gardens can be used to grow various plants, including cannabis. They are prevalent among indoor cannabis growers because they can be set up in a controlled environment, allowing for year-round cultivation. 

Hydroponic systems can be relatively low-maintenance, making them a good option for busy growers. However, they require some initial setup and ongoing monitoring to ensure that the plants get the proper nutrients and pH levels.


An aeroponic growing system is an indoor cannabis cultivation method that uses air or mist to deliver nutrients and water to the plants' roots. Instead of growing the plants in soil, aeroponics uses a closed-loop system that sprays a nutrient-rich water solution onto the exposed roots of the plants suspended in the air. 

This method allows the plants to absorb more oxygen and nutrients, leading to faster growth and higher yields. Aeroponic systems are known for their precision and control, allowing growers to closely monitor and adjust the nutrient levels and pH of the water solution. However, they can be more expensive and require more maintenance than other indoor growing methods.


An aquaponic growing system is a type of indoor gardening system that combines elements of hydroponics and aquaculture to create a symbiotic environment for plants and fish.

In an aquaponic system, fish are kept in a tank, and their waste is used to fertilize the plants, which are grown in a separate hydroponics growing system. The plants, in turn, help to filter the water for the fish. 

This closed-loop system allows both the fish and the plants to thrive while conserving water and reducing the need for synthetic fertilizers. 

Aquaponic systems are an excellent choice for indoor cannabis growing because they provide a natural and sustainable way to grow cannabis without the need for soil.

Indoor Grow Systems

Grow Tent

A cannabis grow tent is a small, portable structure specifically designed for growing cannabis plants indoors. A grow tent is typically made of a sturdy, lightweight frame covered with a reflective material on the inside, which helps to maximize the use of light for the plants. 

Grow tents come in various sizes, making them suitable for a small or large indoor garden system. They are also equipped with vents and ports for air circulation and temperature control and for attaching lights, fans, and other equipment. 

Grow tents provide a controlled environment for cannabis plants to thrive, making them an excellent choice for those who want to grow cannabis indoors.

Grow Box or Cabinet

A cannabis grow box or cabinet is a self-contained, indoor growing system designed to cultivate cannabis plants. 

These units are typically outfitted with all the necessary components for successful plant growth, including grow lights, ventilation, and temperature and humidity control. Grow boxes and cabinets come in various sizes and configurations, making them suitable for both hobbyists and professional growers.

One of the main benefits of using a grow box or cabinet, also known as a smart garden, is the ability to precisely control and optimize the growing environment for your cannabis plants, which can result in higher yields and better quality buds. 

Additionally, grow boxes and cabinets are generally easier to set up and maintain than traditional grow rooms, making them a popular choice for many cannabis cultivators.


A cannabis closet grow system is a setup for growing cannabis plants indoors in a small, enclosed space such as a closet. These indoor gardens can be as simple as a few pots with plants or as complex as a fully automated hydroponic setup.

The main advantage of a cannabis closet grow system is its discreetness and the ability to easily control the growing environment. They are a good option for those who do not have much space or want to keep their cannabis growing operation hidden. 

However, it is important to properly ventilate the closet to prevent excess heat and humidity and minimize the risk of pests and diseases. 

Overall, a cannabis closet grow system can be a convenient and effective way to grow cannabis at home as long as it is set up and maintained properly.

Commercial Facility

commercial cultivation facility is a building or space used specifically to grow cannabis on a large scale. These facilities are usually operated by businesses or organizations licensed to cultivate cannabis for medical or recreational purposes. 

Commercial facilities often use advanced growing systems and technologies to maximize efficiency and yield, such as controlled environments, hydroponic systems, and LED lighting. 

There are over 300,000 jobs in the cannabis industry. CTU trained me for one of them!
