B'cuzz Clay Pebbles are of the highest quality and like the other substrates in the B'cuzz range, they carry the RHP quality mark. Clay Pebbles have certain physical advantages due to their special structure and texture, and they will improve the availability of water to the plant and its root capacity. The amount of roots present in the substrate will have a direct influence on the pore structure and the water/air relations in the pot. Such roots will have a positive influence on proportion of water present and its division throughout the medium. Seedlings or cuttings will root extremely fast in B'cuzz Clay Pebbles. The Clay Pebbles are primarily to be used as a medium for growing, but they can also be used as an additive to a soil substrate. Adding a layer at the bottom of a pot when using soil allows more oxygen into the soil substrate and helps with drainage.
