Multiblocks are designed for cuttings or seed propagation and fit in the holes cut in the larger Rockwool cubes. The blocks come in sheets cut to fit in a standard 10" x 20" propagation tray. The blocks are tapered or V shaped to create an air space below to allow for air pruning, helping roots grow within rather than between individual blocks. 98 cubes per sheet.
