Vermiculite is a mica that has a great capacity to retain water and nutrients and then slowly release them as the crop needs them. It is used in drawer or tray seedlings to obtain a suitable granulometry. Also to avoid the loss of nutrients through the "washing" of the soil, either due to irrigation water or rain. It is ideal mixed with peat, used as a rooter for cuttings or segments.
Very light material that increases the retention of nutrients, prolonging the fertility of the soil for much longer.
