PVP Super Coarse Vermiculite Professional Grade - Excellent Soil Conditioner - Super Coarse Grade Granule – 103 Quarts - 4 Cubic Foot
- Horticultural super coarse vermiculite is permanent, clean, odorless, non-toxic, sterile and pH neutral. It will not deteriorate, turn moldy or rot. It is typically mixed with soil, peat, composted pine bark, fertilizers, pesticides and herbicides and promotes faster root growth and quick anchorage to young roots.
- Horticultural super coarse vermiculite is a natural ‘wicking’ mineral. The vermiculite granules attract and hold ammonium, potassium, calcium and magnesium needed for the growing plants. Additionally, the vermiculite/peat mixture provides excellent aeration and retention of plant food and moisture. The growing plants take what they need (food, air, water, minerals), when they need it from the vermiculite granules, thus less maintenance for the grower and healthier plants with higher yields.
- Because the super coarse vermiculite granules can soak up to over three times its original volume in water it can be a very useful component in a passive hydroponics system that does not utilize pumps or other devices to force the nutrient solution to flow. Additionally, it is perfect for seed germination and cutting propagation.
