De-Gnat Advanced Insect Shield - 10kg

Diatomaceous Earth (DE) creates an effective barrier at the top of the substrate with abrasive properties to deter fungus gnat (Sciarid fly). De-Gnat is comprised of specially sized DE particles that control gnat and other various pests at different points in their lifecycles.

De-Gnat is made from ancient fossilized remains of a unique sea-kelp. This naturally refined compound provides many benefits for your garden. Not only for protecting plant roots, De-Gnat provides a natural source of silica and increases substrate aeration, while reducing compaction. De-Gnat also improves nutrient uptake and microbial activity, whilst acting as a thermal barrier against fluctuations in substrate temperature.

How to apply:

Add a layer 3cm of De-Gnat on top of the substrate

Make sure all growing media (substrate) is fully covered at all times

Re-apply during the growing cycle to keep this physical barrier intact

Irrigate with care to avoid disturbing the protective layer of De-Gnat
