Nutrifield’s Coco Premium Perlite Blend 70/30 contains a blend of 70% coco coir and 30% perlite which presents many advantages for the modern gardener. As drainage and air flow are improved, more aggressive feeding programs can be implemented without fear of overwatering. Drainage capacity is optimised, so fear of overwatering will be a thing of the past. Plants get constant supply of fresh, cool air and as much nutrients as the coco coir can hold while the excess flows through. The increased air flow within the medium allows for greater root transpiration, respiration, and feeding which accelerates growth.
