An important feature of Atami Bi-Grow Mix is its air/water ratio. The gaps present in Bi-Grow Mix may be filled with water and air. Thanks to the coco fibres, gaps filled with air take in a higher volume, which means more oxygen benefits for the plant. Bi-Grow Mix does not retract and easily absorbs water. Nutrients are gradually released and are thus constantly available for the plant. The presence of coco fibres facilitates root development.
As far as the amount and ratio of the fertilizers is concerned, this substrate can be considered as medium.
