Aeroponics is a method of growing plants in an air or mist environment without the use of soil. In the case of cannabis cultivation, aeroponics involves suspending the plants in a grow chamber and misting the roots with a nutrient-rich water solution.
Benefits of growing cannabis in aeroponics
Aeroponics is a specialized method of growing cannabis, and it is not as common as other methods, such as soil-based cultivation or hydroponics. However, it is gaining popularity among some cannabis growers due to these potential benefits:
Faster growth rates. Because the plants are provided with a consistent supply of nutrients and moisture, they can grow faster in an aeroponic system compared to soil-based systems.
Higher yields. Aeroponics can also result in higher yields compared to other growing methods, as the plants can absorb more nutrients and water, leading to increased growth.
Precise nutrient delivery. With aeroponics, growers can more precisely control the amount of nutrients the plants receive, which can help optimize growth and increase yields.
Greater control over the growing environment. In an aeroponic system, the grower has more control over the temperature, humidity, and light levels, which can help create a more optimal growing environment for the plants.
Reduced risk of pests and diseases. Because the plants are grown in an air or mist environment, they are less likely to be affected by pests and diseases that can be found in soil.
Water and nutrient conservation. Because the plants are not grown in soil, there is less water and nutrient runoff, which can help conserve resources and reduce waste.
Growing aeroponic cannabis at home
Before you get started, keep in mind that while aeroponics can provide many benefits, it can also be more expensive and labor-intensive compared to other growing methods, as it requires a specialized setup and regular monitoring and maintenance.
From seed
To grow aeroponic cannabis from seed, follow these steps:
- Set up your aeroponic grow system. Set up your aeroponic grow system according to the manufacturer’s instructions or your own design. Make sure the grow chamber is properly sealed and the nutrient delivery system is working properly.
- Germinate your cannabis seeds. Before planting your cannabis seeds, you will need to germinate them to encourage growth. You can do this by soaking the seeds in water for 24-48 hours and then transferring them to a damp paper towel or rockwool.
- Plant your cannabis seeds. Once your seeds have germinated, you can transfer them to the aeroponic grow system. Place the seeds in small cups or net cups and fill them with a rooting medium such as Rockwool or perlite.
- Set up the nutrient delivery system. Your aeroponic grow system will need a nutrient delivery system to provide the plants with the necessary nutrients and moisture. You can use a drip system, a spray system, or a mist system.
- Monitor and maintain the grow system. As your cannabis plants grow, you must monitor and maintain the grow system regularly. This includes monitoring the nutrient levels in the water, adjusting the pH as needed, and controlling the temperature and humidity in the grow chamber.
Using clones
To grow aeroponic cannabis using clones, follow these steps:
- Obtain clones. You can obtain cannabis clones from a licensed dispensary or grower or take cuttings from a healthy adult cannabis plant and root them yourself.
- Set up your aeroponic grow system. Set up your aeroponic grow system according to the manufacturer’s instructions or your own design. Make sure the grow chamber is properly sealed and that the nutrient delivery system is working properly.
- Plant your cannabis clones. Once you have your clones, you can transfer them to the aeroponic grow system. Place the clones in small cups or net cups and fill them with a rooting medium such as Rockwool or perlite.
- Set up the nutrient delivery system. Your aeroponic grow system will need a nutrient delivery system to provide the plants with the necessary nutrients and moisture. You can use a drip system, a spray system, or a mist system.
- Monitor and maintain the grow system. As your cannabis plants grow, you must monitor and maintain the grow system regularly. This includes monitoring the nutrient levels in the water, adjusting the pH as needed, and controlling the temperature and humidity in the grow chamber.
Tip: Use foam collars, also known as foam rings or foam inserts, to help the plant stand upright
and hold them in place. They are made of a lightweight, spongy foam material and are placed around the base of the plant to provide support and prevent the plant from tipping over. In addition to providing support for the plants, foam collars can also help to conserve water and nutrients in the grow system. They can absorb excess water and nutrients and release them back into the grow system as needed, which can help reduce waste and improve the system’s efficiency.
Aeroponic vs hydroponic: which is better for growing cannabis at home?
Both aeroponics and hydroponics can be effective methods for growing cannabis at home, and which method is best depends on your specific needs and preferences. Here are some factors to consider when deciding between aeroponics and hydroponics for growing cannabis at home:
Cost. Aeroponics systems can be more expensive to set up compared to hydroponics systems, as they require specialized equipment such as a grow chamber and a nutrient delivery system. However, both methods can be more expensive than soil-based cultivation in the long run due to the ongoing cost of nutrients and equipment maintenance.
Ease of use. Hydroponics systems can be easier to set up and maintain compared to aeroponics systems, as they do not require as much monitoring and maintenance. However, both methods require a certain level of knowledge and experience to set up and maintain properly.
Growth rate and yields. Both aeroponics and hydroponics can result in faster growth rates and higher yields compared to soil-based cultivation, as the plants have a consistent supply of nutrients and moisture. However, aeroponics may have the potential for even higher yields due to the precise delivery of nutrients to the plants.
Pest and disease prevention. Both aeroponics and hydroponics systems can be less prone to pests and diseases compared to soil-based systems, as the plants are not grown in soil and the grow environment is more controlled. However, it is important to properly sterilize the equipment and maintain a clean growing environment in both systems to prevent the spread of pests and diseases.
Ultimately, the choice between aeroponics and hydroponics for growing cannabis at home will depend on your specific goals, budget, and level of experience. It is important to carefully consider these factors and do your research before deciding on a grow method.
