How to use Rock dust in hydroponic

Rock dust can be used as a supplement in hydroponics to provide plants with additional minerals and trace elements. Here’s how to use rock dust in hydroponics:

  1. Choose the right type of rock dust: Different types of rock dust have different mineral compositions, so it’s important to choose one that is appropriate for the plants you are growing. For example, basalt rock dust is high in iron, while granite rock dust is high in potassium.

  1. Mix the rock dust with water: Mix the rock dust with water to create a slurry. The ratio of rock dust to water will depend on the type of rock dust you are using, but a general rule of thumb is to mix 1 part rock dust to 10 parts water.

  1. Add the rock dust slurry to the hydroponic system: Slowly pour the rock dust slurry into the hydroponic system, making sure to distribute it evenly.

  1. Monitor the nutrient levels: Regularly monitor the nutrient levels in the hydroponic system, including pH and EC, and make adjustments as necessary. Overuse of rock dust can lead to nutrient imbalances, so it’s important to use it in moderation.

  1. Repeat the process: Repeat the process of adding rock dust slurry to the hydroponic system every 2-4 weeks, or as needed.

  2. It’s important to note that rock dust is not a complete nutrient solution and 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 rock dust to use for your specific system and plants.
