It also includes pH buffering agents to help maintain nutrient balance and improve uptake.
Used in combination with Holland Secret Grow and Bloom, this micro mix ensures your plants are strong, resilient, and capable of reaching their full genetic potential — from seedling through harvest. It’s built to work across all growing media, including hydroponics, coco, and soil.
