Pure Zym

Accelerates the decomposition of plant residues

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.


In our new formula, we added a greater variety of enzymes which speed up and improve the process to break down dead plant material. This allows the plant to absorb the dead plant material even faster and better than before.

The plant residues that break down near your root environment, create space for nutrient absorption.

Because the mixing ratio is 1:1,000, Pure Zym is very easy to use.

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.
