Vermiculite - Coarse Grade, 8 - 12mm

Vermiculite is a lightweight horticultural growing medium designed to improve moisture retention, aeration and growing conditions around plant roots. Its absorbent structure allows it to hold water and gradually release moisture back into the growing medium, making it particularly useful for seed sowing, propagation, potting mixes and container gardening.

At Growcery Gardening, our vermiculite is carefully selected for use by home gardeners, growers and horticultural enthusiasts. It can be used for propagation applications or blended with compost, coco coir and other growing media to create a lighter, moisture-retentive mix.

Benefits:

- Excellent Moisture Retention: Absorbs and holds water, helping growing media remain evenly moist for longer.

- Supports Seed Germination: Ideal for covering freshly sown seeds and helping maintain moisture during germination.

- Useful for Propagation: Can be incorporated into propagation mixes for seedlings and young plants.

- Improves Growing Media: Helps create a lightweight mix while supporting moisture management around plant roots.

- Easy to Mix: Can be blended with compost, coco coir, perlite and other horticultural substrates depending on the needs of your plants.

- Lightweight and Convenient: Easy to handle, store and incorporate into pots, trays and larger growing containers.

How to Use Vermiculite

For seed sowing, apply a light layer over the surface after sowing to help retain moisture. For potting and propagation mixes, blend it with your chosen compost or growing medium according to the moisture requirements of the plant.
