Know before you buy
This specific ratio is engineered to balance moisture retention with high-level drainage. The coco coir holds the necessary water for root uptake, while the 30% perlite content ensures the root zone remains oxygenated, which is critical for preventing root rot.
Yes, PRO-MIX CPX AGTIV REACH is OMRI Listed, meaning it meets the standards for use in organic production systems.
This product is a base growing medium and does not contain a significant nutrient charge. Because it is inert, you will need to provide a consistent liquid feeding program tailored to your specific crop's growth stage.
Because this medium drains very efficiently, you may find yourself watering more frequently than you would with a standard peat-based soil. It is designed to allow for more precise, frequent fertigation without the risk of waterlogging the root zone.
While coco coir is durable, it can break down over time and accumulate salts from fertilizers. For best results with high-value crops, it is generally recommended to use fresh medium for each cycle to ensure optimal aeration and prevent pathogen buildup.
