Plagron Pure Zym Enzyme Soil Improver

Plagron Pure Zym is a liquid soil improver made with natural enzymes. It helps break down dead plant material in the growing medium, releasing nutrients that support soil life and creating more space around the roots for nutrient and oxygen uptake.

Pure Zym can be used throughout the cultivation period alongside a suitable feeding programme. It is particularly relevant where plant residues collect in soil, peat-based mixes or coco substrates.

Why use Pure Zym?

  • Helps break down dead plant material in the growing medium.
  • Releases nutrients from decomposing plant residues to support soil life.
  • Supports the growing medium's capacity for nutrient and oxygen uptake.
  • Concentrated formula dosed at 1 ml per litre of water.

How to use

Shake well before use. Add 1 ml of Pure Zym per litre of water and use the prepared solution each time plants are irrigated throughout the cultivation period. Follow the product label and the requirements of the growing medium.

Growing system compatibility

Pure Zym is of organic origin. Do not use it in NFT, DWC or aeroponic systems. Growers using recirculating hydroponic equipment should check compatibility before adding any organic-origin product to the system.

Available sizes

Choose from 250 ml, 500 ml, 1 litre, 5 litres and 10 litres, subject to current availability.

Turn Dead Root Matter into Available Nutrition

Keep your growing medium working harder with Plagron Pure Zym, a concentrated enzyme-based soil improver designed to accelerate the natural breakdown of dead plant material around the root zone.

Its blend of natural enzymes helps convert plant residues into smaller components, releasing additional nutrients while creating more space within the substrate for improved oxygen and nutrient absorption. This helps maintain an active, efficient root environment throughout the growing cycle.

Highly concentrated at just 1 ml per litre, Pure Zym can be used with every watering and is suitable for all substrates, making it an easy addition to soil, peat and coco feeding programmes.

Frequently Asked Questions

Pure Zym is an enzyme-based substrate improver that accelerates the breakdown of dead plant material around the roots. As this material decomposes, additional nutrients become available and more space is created within the root environment for nutrient and oxygen absorption.

Enzymes act as catalysts that speed up natural processes. Pure Zym contains several types of enzymes that break larger pieces of plant residue into smaller components, allowing them to be broken down and reabsorbed more efficiently.

Shake Pure Zym well before use and add 1 ml per litre of water, giving a dilution ratio of 1:1,000. Plagron recommends using the solution each time your plants are watered.

Pure Zym can be used throughout the entire cultivation period. Regular use helps continually break down dead plant residues and maintain an efficient growing medium as plants develop.

Yes. Plagron states that Pure Zym is suitable for all substrates, including soil and coco-based growing media. This makes it a versatile enzyme additive for a range of hand-fed growing setups.

Pure Zym is of organic origin, so Plagron advises against using it in hydroponic methods such as NFT, DWC and aeroponics. For those systems, choose products specifically designed for hydroponic cultivation.
