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. Case of 2940 cubes, 30 sheets.
