Kelp meal is a type of seaweed that can be used as a supplement in hydroponics to provide plants with additional minerals and trace elements. Here’s how to use kelp meal in hydroponics:
- Choose the right type of kelp meal: Kelp meal is typically made from different types of seaweed such as Ascophyllum nodosum and Laminaria species. They have different mineral compositions and ratios, so it’s important to choose one that is appropriate for the plants you are growing.
- Mix the kelp meal with water: Mix the kelp meal with water to create a slurry. The ratio of kelp meal to water will depend on the type of kelp meal you are using, but a general rule of thumb is to mix 1 part kelp meal to 20 parts water.
- Add the kelp meal slurry to the hydroponic system: Slowly pour the kelp meal slurry into the hydroponic system, making sure to distribute it evenly.
- Monitor the nutrient levels: Regularly monitor the nutrient levels in the hydroponic system, including pH and EC, and make adjustments as necessary. Overuse of kelp meal can lead to nutrient imbalances, so it’s important to use it in moderation.
- Repeat the process: Repeat the process of adding kelp meal slurry to the hydroponic system every 2-4 weeks, or as needed.
It’s important to note that kelp meal contains a lot of minerals and trace elements, it’s a good source of Potassium, Iron, and other essential micronutrients, but it’s not a complete nutrient solution, it should be used in addition to a regular hydroponic nutrient solution. Also, different hydroponic systems have different requirements, so it’s best to consult with experts to determine the appropriate amount of kelp meal to use for your specific system and plants.
