Compatible with automatic systems, drip or manual irrigation, it is a stable substrate that supports frequent applications without collapsing. Ideal for demanding plants such as cannabis, it accelerates root colonization and reduces post-transplant stress.
This substrate serves as a neutral and balanced base for all types of coco crops. Its fertilizer-free formulation allows you to fully customize nutrition with liquid fertilizers, from cuttings to adult plants. It is perfect for those seeking a clean medium that guarantees control over EC and pH, as well as superior oxygenation of the root system. It can also be used in mixtures with perlite or clay pebbles to optimize drainage and aeration, especially in high ambient humidity conditions.
The Washed & Buffered Coco 50 L. ATAMI is composed exclusively of washed and buffered coconut fiber. Its balanced texture, with fine and coarse particles, offers an ideal balance between water retention and oxygen. It is a totally inert medium, which means it does not provide salts or nutrients by itself, allowing precise feeding through irrigation. Thanks to its low conductivity, it maintains a range of stable pH between 5.5 and 6.5, creating the perfect conditions for efficient nutrient absorption.
Preparation: open the bag and aerate the coco before use. No need to wash or stabilize, it is already buffered and ready to plant.
Initial watering: lightly moisten with water adjusted to pH 5.8 before transplanting. It is recommended to use water with an EC lower than 0.4 mS/cm.
Transplant: fill the pots without compacting the substrate. Place the cuttings or plants and perform the first watering until a slight drainage is observed.
Nutrition: add liquid fertilizers from the first watering, as it contains no fertilizer. Compatible with the Atami B’Cuzz Coco A+B range and stimulants such as Root Stimulator or Bloom Stimulator.
Watering: maintain constant moisture without waterlogging. It is recommended to alternate light waterings and 10–20% drainage to avoid salt buildup.
Reuse: can be used several times if properly washed and residual organic matter is removed between harvests.
