Halamanin's Vermiculite (Coarse) is a well-known for being an effective growing medium. Commonly used in compost formulations with coir or peat, it creates ideal conditions for plant growth.
It improves aeration of the soil, promotes a consistent release of added fertilizer and improves moisture retention of the soil.
It is also heated to expand the particles.
This expansion enables it to absorb moisture when used as a potting medium. Vermiculite can soak up 3 to 4 times its volume in water.
It also attracts plant nutrients such as potassium, magnesium, calcium and phosphorus.
Vermiculite is ideal for plants that prefer lots of water.
