Mills Coco & Cork is a high-performance growing substrate developed by Mills Nutrients, designed to offer the optimal balance of air and water retention for professional horticulture. This innovative medium blends premium buffered coco coir with natural cork, resulting in a lightweight, highly aerated structure that promotes vigorous root development and nutrient uptake. The cork component not only improves drainage but also enhances microbial activity, creating a healthier root zone and reducing the risk of compaction over time. Coco & Cork is ideal for growers using drain-to-waste or recirculating systems and is suitable for both indoor and greenhouse environments. Mills substrates and nutrients are a great solution for providing your plants with the support they need to grow. So don’t hesitate to check out their Organics Base or the Mills Seed Starter Kit.
