PRO-MIX® HP-CC MYCORRHIZAE™ is a lightweight, high-porosity peat-based growing medium that contains chunk coir. It ensures optimum growth, especially when high air capacity and extra drainage are required. It is ideal for water-sensitive crops, rooting cuttings and/or low-light growing conditions that contains a beneficial mycorrhizal inoculum (Glomus intraradices). These microscopic fungi attach to and colonize the root systems working in symbiosis with plants. It benefits the plant by increasing water and nutrients acquisition (especially Phosphorus, Copper and Zinc). This symbiotic relationship between fungi and plant, results in an overall improved plant growth PRO-MIX® HP-CC MYCORRHIZAE™ is suitable for a wide variety of horticultural plants.
