Coco Substrate contains an RHP quality mark that guarantees a coconut substrate of excellent quality. The coconut fibres have been properly washed, steamed and buffered, which guarantees an optimum growing substrate. The coconut contains sufficient nutrition for the 1st week of the growing cycle, afterwards you can add water with liquid fertilizers and stimulators for optimal results. Coconut has a perfect structure, which retains the nutrient solution easily and is thus quickly absorbed by the roots of the plant. Coconut substrate also remains fairly airy, so the roots receive much oxygen. The plants thus get a healthy and strong root system and develop at a fast pace.
