Supalite Black Sand - Fine Grain Bonsai Growing Media

Supalite Black is a budget price lightweight fired clay aggregate of UK origin that's great for mixing with other bonsai soil ingredients. The open honeycomb structure of this product holds great amounts of water, promotes exceptional air circulation and lots of microbial activity that quickly releases the nutrients from organic fertilizers. The particles are frost-proof and so will not break down, even after many years in the pot.

This product is the fine 'Sand' grade of Supalite. Traditional horticultural sand or the coarser Japanese river sand almost entirely consists of fine flint particles. Whilst these may in some circumstances promote drainage they add a lot of weight and bring nothing in relation to bioactivity to a mix. Supalite sand brings great benefit to fine particle soil mixes used in bonsai and specialist horticulture as outlined above.

We recommend using this great product in conjunction with other fine growing media including Coir or composted bark. By blending different products together it's possible to create soil mixes very close to the ideal conditions for individual plants. In our tests we found that using up to 60% by volume produced a very open structure soil that encouraged dense root production required for the maturation of quality bonsai trees. It also reduced the weight of the soil considerably. Up to 40% weight saving over some volcanic soils and 60% lighter than horticultural grit.
