Atami Hydro Rokz 60/40 Cocos:


  1. Cultivation on a coco substrate and hydroponic growing are popular cultivation methods. Every grower has his own preference and every substrate has its own characteristics. Atami Hydro Rokz Cocos 60-40 Growing Medium combines the best of both worlds with its well-balanced blend of clay pebbles and top quality coco peat.
  2. Hydro Rokz Cocos 60-40 offers many benefits of growing hydroponically. The clay pebbles provide excellent drainage as they retain nearly no water. This decreases the risk of over-watering. When the water is drained, fresh air enters the root zone and gives this substrate a high air ratio, for optimal root development!
  3. Adding coco increases the water retention of the substrate. Coco offers a buffer between watering times, as it makes sure moisture levels near the roots stay stable. And, it holds on to some nutrients as well!
