Cultilene CRB Small (25mm) Propagator Cubes Trays of 150

Cultilene CRB Small (25mm) Propagator Cubes + Tray These starter cubes are ideal for cuttings and seedlings The variation in small and large pores throughout the block ensures that the roots are always supplied with sufficient air and water. In addition, the water content of the block can be controlled with great precision. The efficient pattern of the pores ensures that water and nutrients are distributed uniformly throughout the block, thereby offering excellent control over both the nutrient solution and the pH. This promotes the development of a strong root system during propagation. The uniform distribution and vertical structure of the fibres results in the same resistance for each root, thereby ensuring that the roots distribute themselves uniformly throughout the block. SBS blocks are supplied in a specially manufactured black tray which excludes light from the root zone.
