Coco peat is  a very good raw material for agriculture, especially high-tech agriculture. Fresh coconut husk (untreated) contains 2 important substances that greatly affect the roots of sprouts, the most are 2 Tannins (the acrid substance found in tea, coco peat, … soluble in water) and Lignin (an astringent that dissolves only in alkaline media). These two ingredients block all the suction lines – inhale the nutrients of the sprouts’ roots, which are difficult to decompose. If used directly, it will stunt the plant, slow growth or poison the seedlings leading to death.
