Coco Mega Brick Premium Coir Peat Organic Plant Growth Medium 55L Nutrifield

Nutrifield Coco Mega Brick is your ultimate pre-buffered natural growing medium. This guarantees the best start for any cultivation. Pre-buffered to prevent calcium and magnesium lockout. Lockout occurs due to the coco coir having a negative charge complex that is surrounded primarily by Sodium and Potassium. With the RHP quality mark you increase the security that the substrate complies with the quality requirements concerning for instance water uptake, air content, pH, EC and nutrients. It also offers more security that the substrate is pure and clean and that it can be used without risks for the culture. The RHP quality mark monitors the quality of growing media in the chain, from raw materials production until processing and delivery at the company of the user.
