Why Choose Vermiculite

Vermiculite is a naturally occurring mineral that expands when heated, creating a lightweight, highly absorbent growing medium. Unlike perlite (which primarily improves drainage), vermiculite excels at moisture retention while still maintaining excellent aeration. The medium coarse grade offers the ideal balance of water-holding capacity and air space for most horticultural applications.

Usage Guidelines

Seed starting: Use 100% vermiculite or mix 50/50 with perlite
Potting mixes: Blend 10-30% vermiculite with peat moss, coir, or compost
Hydroponics: Mix 50/50 with perlite for optimal moisture and drainage balance
Soil amendment: Incorporate 10-20% into existing soil to improve structure
Rooting cuttings: Use 100% vermiculite or mix with perlite
