How it Works

Aeroponics is a plant-growing technique that uses air to supply nutrients to the roots. This technique involves suspending the plants in the air and spraying them with a nutrient-rich mist. This mist provides the required nutrients, water, and oxygen directly to the plants’ roots without soil. Here’s how the process works:

  • Step 1: Root Suspension
  • First, the plants in aeroponics are suspended in net pots, which are located on top of a reservoir. The net pots have holes at the bottom, allowing the roots to hang down into the reservoir.

  • Step 2: Nutrient Spray
  • Next, a nutrient-rich mist is sprayed onto the roots using misting nozzles. This mist is made up of a solution of water, minerals, and other essential plant nutrients.

  • Step 3: Root Growth
  • The sprayed mist provides the plants with a constant supply of water, oxygen, and nutrients. As a result, the roots grow faster and stronger, which leads to faster growth and higher yields.

  • Step 4: Oxygenation
  • The oxygenation of the root system is another essential aspect of the aeroponic process. The roots are not submerged in water, allowing them to receive adequate oxygenation. Oxygen is essential for healthy root development and helps to prevent root rot.

  • Step 5: Recirculation
  • The nutrient solution that is not absorbed by the roots goes back into the reservoir, where it is recirculated, providing a continuous cycle of nutrients for the plants. This recirculation makes aeroponic systems very water-efficient.

By using aeroponics, cannabis plants can grow up to five times faster than traditional soil methods. This growth rate is due to the constant supply of nutrients and oxygen directly to the roots, allowing cannabis plants to grow healthier and stronger.

Benefits for Cannabis

Aeroponics can bring numerous benefits for cannabis plants, leading to improved growth, higher yields, and better overall plant health. One of the main advantages of aeroponics is that it allows for maximum oxygenation of the roots, which leads to faster nutrient absorption and better plant growth.

Another benefit of aeroponics is that it can help to minimize the risk of pests and diseases. With plants growing in a closed environment, the risk of external contamination is greatly reduced, and any issues with pests or diseases can be identified and isolated early on.

Aeroponics allows for precise control over nutrient delivery, meaning that plants can receive the exact amount of nutrients they need at each stage of growth. This leads to better nutrient uptake and more efficient use of resources, ultimately resulting in healthier plants and larger yields.

Since there is no soil involved in aeroponics, there is less mess and less chance of nutrient runoff, making it a cleaner and more sustainable option for cannabis growers.

Finally, aeroponic systems can be easily automated, making it possible to monitor and adjust key environmental factors like temperature, humidity, and CO2 levels, leading to optimal plant growth and greater yields.

The benefits of choosing aeroponics for cannabis cultivation are numerous, and can lead to healthier, more productive plants and higher quality yields.

Keep pH Within Range Test and adjust the pH level regularly to avoid nutrient deficiencies or toxicities.

By properly measuring and mixing the nutrient solution, you can ensure that your cannabis plants are receiving the optimal amount of nutrients to thrive in your aeroponic system.

Feeding Schedule

A well-maintained feeding schedule is crucial for the success of any cannabis aeroponic system. It ensures that the plants receive the right amount of nutrients at the right time, maximizing growth and yield while minimizing the risk of nutrient burn.

Vegetative Stage Feeding Schedule: During the vegetative stage, cannabis plants require high amounts of nitrogen to promote leaf and stem growth. It’s recommended to use a nutrient solution with an N-P-K ratio of 3-1-2, such as Nutrient Solution #3. Feed the plants with this solution for 10-14 days, depending on the strain and environmental conditions.

Transition Stage Feeding Schedule: As the plants transition from vegetative to flowering stage, they will require lower nitrogen levels and higher levels of phosphorus and potassium. A nutrient solution with an N-P-K ratio of 1-2-4, such as Nutrient Solution #1, is suitable for this stage. Feed the plants with this solution for 7-10 days.

Flowering Stage Feeding Schedule: In the flowering stage, the plants will need lower nitrogen levels and higher phosphorus and potassium levels. A nutrient solution with an N-P-K ratio of 1-4-5, such as Nutrient Solution #4, is recommended for this stage. Feed the plants with this solution for 10-14 days.

Ripening Stage Feeding Schedule: During the ripening stage, the plants require even lower nitrogen levels and higher phosphorus and potassium levels to encourage bud maturation. A nutrient solution with an N-P-K ratio of 0-5-4, such as Nutrient Solution #2, is best for this stage. Feed the plants with this solution for 7-10 days before flushing.

It’s important to pH test the nutrient solution before feeding the plants and adjust it to the optimal levels for cannabis growth, which is between 5.5-6.5 pH. Overfeeding can cause nutrient burn and damage to the plants, while underfeeding can result in stunted growth and reduced yield. Use a digital TDS meter to measure the strength of the nutrient solution, which should be maintained at around 800-1000 ppm during the vegetative stage and 1000-1200 ppm during the flowering stage.

Following a proper feeding schedule with the right nutrient solution can help maximize the yield and quality of cannabis plants in an aeroponic system. It’s important to monitor the plants daily for any signs of stress or nutrient deficiencies and adjust the feeding schedule accordingly.

Flushing and Harvesting

After weeks of monitoring and caring for your cannabis plants, it will soon be time to harvest. Before that, however, you must perform a crucial step known as flushing. Flushing is the process of removing excess nutrients and chemicals that may have accumulated in the plant’s tissues and roots. This can be done by simply watering the plants with plain water for a period of time before the harvest.

Why is flushing important?

Flushing is important for a few reasons. Firstly, it helps to improve the taste and aroma of your buds. The excess nutrients and chemicals can affect the flavor and smell of the final product, resulting in a harsh and unpleasant taste. Flushing also helps to improve the burnability of your buds, which means they will smoke smoother and more evenly. Additionally, flushing can help to prevent nutrient lockout, which is when the plant is unable to absorb certain nutrients due to an imbalance of pH levels.

How to flush your plants

To begin the flushing process, stop using your nutrient solution and instead, give your plants plain water for the last 1-2 weeks of their growth cycle. The amount of time needed may depend on the strain and growing conditions, so it is best to monitor your plants closely.

During this period, be sure to water your plants thoroughly to ensure that the excess nutrients are being flushed out. You may notice that the leaves start to yellow during the flushing period. This is a normal part of the process as the plant uses up its remaining nutrients.

Harvesting your plants

After the flushing period, it is time to harvest your plants. The timing of the harvest will depend on the strain and the maturity of the trichomes (the tiny resin glands on the buds). A good rule of thumb is to harvest when the trichomes have turned a milky white color, with some amber or brown ones as well.

To harvest, use sharp, clean scissors to cut the branches of your plants. Hang the branches upside down in a cool, dry, and dark place to dry for 5-7 days. Once they are dry, trim off any excess leaves and store the buds in airtight jars to cure for a few weeks.

Flushing and harvesting are crucial steps in producing high-quality cannabis. By following these steps, you can ensure that your buds will have a smooth taste and aroma, as well as a potent and enjoyable experience.


In conclusion, using aeroponics to grow cannabis plants can be highly beneficial for maximizing plant health and yield. However, it is important to choose the right nutrient solution and effectively use them in the aeroponic system.

Factors to consider when choosing nutrient solutions include the type of cannabis strain, the stage of growth, and the pH level of the water. It is also important to choose a nutrient solution that contains the necessary nutrients for cannabis growth, such as potassium, magnesium, and calcium.
