What are the advantages of this mixed substrate over regular Coco or Hydro substrates? The mixture of coir and perlite combines the best of two substrates. The coconut is completely rinsed and buffered, resulting in a substrate that will balance pH issues. Perlite makes the substrate more airy and provides better drainage. Separate coir or perlite substrates would not combine these qualities.

Plagron Hydro Cocos 60/40 can be reused. Features: Expanded clay, coconut fiber. EC 0.55 - 0.83 EC (1:1.5) [mS/cm]
