Grodan A'OK plugs are designed for seed and cutting propagation prior to "blocking on" into larger growing blocks. Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums. The V-shape design of the plug discourages tangling of roots between the plugs in the A'OK plug sheet. Sheet fits a standard 10x20 inch flat.
