The soil mixes stocked at Holland Horticulture are made up of different substances, some including bat guano and worm manure, to achieve certain properties. Also available, Vermiculite, Diahydro and Perlite are made from porous rock material giving excellent water retention. Diahydro has the added benefit of being rich in silica, which improves cell wall structure and defence against pests.
