All About It
The Pro-Mix High Porosity (HP) with Mycorrhizae is a professional-grade, peat-based growing medium formulated to deliver outstanding results for growers who demand superior drainage, air retention, and root development. Ideal for greenhouse, indoor, and container gardening, this 3.8 cubic foot bale features a blend of sphagnum peat moss, perlite, and a mycorrhizal inoculant to encourage vigorous plant growth and resilience.
This high-performance growing medium is specifically engineered to provide a well-aerated structure, making it perfect for plants that require enhanced root oxygenation and quick drainage—especially during frequent watering cycles. The added mycorrhizal fungi form symbiotic relationships with plant roots, helping improve water and nutrient uptake, boost transplant success, and promote overall plant health.
Please note: This product is available for in-store or curbside pickup only.
