Cocos Premium is by far the cleanest coco substrate on the market — double washed, It's fully buffered and pH-stable, ensuring that your cannabis plants can absorb nutrients without risk of calcium or magnesium lockout. It has the lowest EC value available. That means no hidden salt build-up, no nutrient lockout, and zero transplant shock. For cannabis growers, this translates to faster rooting, more reliable feeding, and stress-free growth from the start with a stable pH. It’s perfect for dialled-in growers who want full control over their nutrients without interference from the medium. Whether you’re hand-watering or running an automated setup, Cocos Premium sets the cleanest foundation for a high-performance grow. Make sure to check out the brand’s Cocos A and Cocos B, designed for ideal feedings and optimal plant growth when growing in coco fiber.
