What is Hydroponics?
Contents
Hydroponics is a method of growing plants that uses nutrient-rich water instead of soil. The word “hydroponics” comes from the Greek words “hydro,” which means water, and “ponos,” which means labor. Hydroponics is essentially laboring with water. This technique allows plants to grow faster and produce higher yields than traditional soil-based methods.
In hydroponic systems, plants grow in a controlled environment where pH levels, nutrients, and lighting can be easily monitored and adjusted. This type of system offers many benefits over traditional soil-based growing methods, including efficient use of water as there is no need for excess watering or drainage. Additionally, hydroponic systems require less space and can be used to grow plants indoors or in limited outdoor spaces.
Hydroponic systems can be designed in various ways, each with its own unique advantages and disadvantages. Drip irrigation systems use a pump to slowly drip nutrient-rich water onto the plant root system. Deep water culture systems, on the other hand, completely submerge the plant roots in nutrient-rich water. Ebb and flow systems alternate between flooding a growing tray with water and then draining it. Aeroponic systems mist plant roots with nutrient-rich water while holding them in the air, and wick systems use a wick to transport water and nutrients to plant roots.
While hydroponic systems offer numerous benefits over traditional soil-based methods, they do require a bit more upfront setup work and maintenance. However, with proper planning and execution, hydroponic systems can provide a highly efficient and effective way to grow plants, including cannabis, at home.

Seed Selection and Germination
Selection of high-quality seeds and proper germination are crucial for successful hydroponic cannabis cultivation. You can buy seeds from reputed breeders or seed banks, but ensure that the strains are suitable for hydroponic cultivation.
Before germinating the seeds, you must inspect them for quality. Check for the color, texture, and size of the seeds. Healthy seeds are usually dark-colored, hard, and smooth. They must be free from any cracks or deformities.
There are various methods for germinating cannabis seeds, but we recommend using the paper towel method. Start by soaking the seeds in a bowl of water for 12-24 hours. Then take two damp paper towels and place the seeds on one of them. Cover them with the other paper towel and place the towels in a sealed plastic bag. Keep the bag in a warm and dark place. Check the seeds every day and add water to the paper towels if they become too dry.
After a few days, when the seeds have germinated, plant them in the hydroponic system. Use a sterile growth medium like rockwool or peat pellets. Place the germinated seed with the root facing down in the growth medium. Don’t cover the seed entirely, just enough to keep it in place. Finally, keep the system in a warm and bright environment to help the plants establish a strong root system.
Vegetative Stage
During the vegetative stage, your cannabis plants focus on growing tall and developing a strong root system. This stage can last anywhere from 3-16 weeks, depending on the strain and how long you want to veg them for.
Lighting: During the vegetative stage, cannabis plants require at least 18 hours of light each day. You can use either LED, HPS, or MH grow lights for this stage. It is important to make sure your plants are receiving enough light, as a lack of lighting can lead to stunted growth and weak stems.
Nutrients: Cannabis plants require a balance of nutrients during the vegetative stage. Your hydroponic system can provide these nutrients by using a combination of synthetic or organic fertilizers. It’s important to monitor the nutrient levels regularly to ensure they’re not too high or too low, as this can negatively affect the growth and health of your plants.
pH levels: Your hydroponic system’s pH levels are also important during the vegetative stage. Cannabis plants prefer a pH range between 5.5-6.5. Maintaining this pH range ensures your plants can properly absorb the nutrients they need to grow.
Training: During the vegetative stage, you can train your plants to fill out and create a bushier plant rather than a tall, single stalk. Topping, low-stress training (LST), and high-stress training (HST) are all popular pruning techniques. Topping involves cutting the top of your plant off, which will encourage the lower branches to grow outward. LST involves bending the branches to grow out, creating a wider plant. HST involves bending or breaking the main stem of the plant, which can create more colas on each branch.
The vegetative stage is essential for producing healthy, vigorous plants that will ultimately produce a higher yield. By providing your cannabis plants with the necessary light, nutrients, and pH levels, as well as any necessary training or pruning techniques, you can ensure your plants will grow into strong, healthy specimens.
Flowering Stage
During the flowering stage of your cannabis plants, you will see the buds begin to form and mature. This is the most crucial stage of the plant’s life cycle, as it will determine the quality and quantity of your yield. To ensure the best outcome, you need to provide the right environment and care for your plants.
Lighting: During this stage, your plants require specific lighting needs. You should switch the lights to a 12/12 schedule, which means that they will receive 12 hours of light and 12 hours of darkness. This will trigger the plants to start flowering. Keep in mind that the intensity and spectrum of the light also play an essential role in the quality and yield of your buds. High-intensity discharge (HID) lights are the most common choice for indoor cannabis grows.
Nutrients: Your plants will require a different nutrient balance during the flowering stage than they did during the vegetative stage. At this stage, they require more phosphorus and potassium, which are essential for flower production. Make sure to adjust your nutrient feeding schedule accordingly.
Temperature and Humidity: The optimal temperature during the flowering stage is between 68-77°F (20-25°C). High humidity levels can cause bud rot and mold, so keep the humidity between 40-50%. Proper ventilation is crucial during this stage to prevent any issues with high humidity levels.
Pruning and Training: It is crucial to continue with pruning and training techniques during the flowering stage. This will encourage better airflow through the plants, which will help prevent mold and mildew. It will also help the plant to focus its energy on producing larger and more potent buds.
Harvesting: Once your plants have reached maturity, it is time to harvest. You will know they are ready when the majority of the pistils (the hairs on the bud) have turned brown, and the trichomes on the buds have turned cloudy or amber. Take care when harvesting to avoid damaging the buds, as this can degrade the quality of the final product.
By following these tips, you can ensure a successful flowering stage for your cannabis plants, and enjoy a high-quality and potent final product.
