PRO-MIX CPX (70 | 30) COIR PERLITE

PRO-MIX CPX (70 | 30) COIR PERLITE is a horticultural perlite made from expanded volcanic glass, used as a soil amendment or standalone component in growing media. It improves drainage and aeration, being pH neutral, sterile, and inert. Adding perlite increases macro-pore space, allowing excess water to drain quickly and oxygen to reach the root zone.

Standard additions range from 20–30% by volume for most cannabis applications, though coco/perlite blends often go higher. It works with any nutrient program, preventing overwatering and maintaining a healthy, aerobic root environment throughout the grow cycle.

This product is for growers looking to enhance soil structure and root health. Whether used in soil or coco mixes, PRO-MIX CPX (70 | 30) COIR PERLITE is essential for preventing overwatering and ensuring optimal root aeration, supporting robust plant growth.
