This medium-weight growing mix is ideal for horticultural crops grown in 4” pots or larger. Made from a blend of processed pine bark, professional-grade sphagnum peat moss, and perlite, it offers excellent drainage with medium water retention, making it a versatile choice for general-purpose cultivation.

Enhanced with BIOFUNGICIDE™ (Bacillus bacterium), it helps reduce root diseases, while MYCORRHIZAE™ (beneficial endomycorrhizal fungus) boosts plant growth, improves nutrient absorption, and enhances overall plant health. Designed for long-term crops, this mix provides a stable growing environment that adapts to seasonal changes. It promotes uniform growth, minimizes root disease issues, and reduces reliance on fungicide drenches.
