Accelerates nutrient absorption

Pure Zym is a soil improver based on natural enzymes. It promotes the accelerated breakdown of dead plant material. This causes additional nutrients that stimulate soil life to be released. Pure Zym also increases the ability to absorb oxygen.

The advantages of Pure Zym
  • Gives protection against the build-up of harmful salts.
  • Increases oxygen absorption capacity.
  • Rapid intake of nutrition for strong growth and flowering.

    Tips from Plagron
  • Use Pure Zym to rinse the substrate before re-use.
  • Frequently asked questions about Pure Zym
    Yes, that's possible. Combining enzymes with Alga Grow and Alga Bloom won't do your plants any harm.

    No, this is normal and is not harmful for your plants. This is caused by the organic ingredients in Pure Zym. After the product has been dissolved in water, a natural bacterial process starts after a while. This causes the smell and can make your solution look cloudy. This does not have any adverse effects on your plants. If you have any questions about this, please contact us at servicedesk@plagron.com.
