Nutrifield® Coco Premium Perlite Blend 70/30 contains a blend of 70% coco coir and 30% perlite, which presents many advantages for the modern gardener. Considering that drainage and air flow are improved, more aggressive feeding programs can be implemented. Drainage capacity is optimised, so fear of overwatering will be a thing of the past. Plants receive a constant supply of fresh, cool air and the required nutrients while excess flows through. The increased air flow within the substrate allows greater root transpiration, respiration, and feeding which accelerates growth.
