De-Nat Natural Fungus Gnat Non-Toxic Barrier for Healthy Plant Growth

Protect your plants from unwanted visitors and improve nutrient absorption with the De-Nat Natural Fungus Gnat Non-Toxic Barrier. This advanced barrier made of diatomaceous earth (DE) provides a natural and safe solution to maintaining the optimum environment for your plants' growth and health.

Features and Benefits

  • Non-toxic and organically sourced: De-Nat is made of DE, a natural silica and calcium compound derived from earth minerals, ensuring a safe and natural solution for your plants.
  • Effective pest control: The abrasive properties of DE granules create a physical barrier over the top of your planting medium, controlling unwanted visitors within your substrate.
  • Improved nutrient uptake: The presence of De-Nat in the plant medium facilitates better nutrient absorption and increased microbial activity.
  • Enhanced aeration and thermal control: De-Nat helps increase porosity and reduce compaction in your substrate, providing excellent thermal insulation.
  • pH stable and compaction resistant: De-Nat maintains consistent pH levels and prevents the substrate from becoming compacted, maximizing aeration and nutrient availability.

How to Use

  1. Add a layer of De-Nat shield approximately 1cm - 3cm deep across the top of the planting medium.
  2. Ensure the medium is fully covered with an even layer at all times.
  3. Reapply throughout the plant's cycle to ensure constant protection.
  4. Replenish the layer if irrigation disrupts the DE layer.
