CocoNot is a soilless medium made from the bark of sustainably harvested redwood trees blended with the fibers of a Kapok fruit. Utilizing a specific layer of the redwood bark and using a proprietary method to grind the material into 6 different size/shaped particles of medium we have created a structure made with the sole purpose to grow plants. We found by adding the fiber of a Kapok fruit we were able to add additional buoyancy, resilience, and drainage. This fiber is made of mostly Lignin: Lignin is generally associated with reduced digestibility of the overall plant biomass, which helps defend against pathogens and pests. A perfect air to water ratio, PH'd and buffered for optimal nutrient uptake CocoNot is free of excess salts and is providing amazing results for growers Dont get left in the coir! CocoNot does not need to be rinsed but should be fed water only for the first 5-10 days. Keep in mind that this material dry's quickly and should be watered regularly... if more water retention is desired ad VermiBlend.
