Grodan Rockwool A-OK Starter Plugs

Grodan A-OK Starter Plugs are designed for starting seedlings and rooting stem cuttings. The finely woven stone wool in the Starter Plug provides the perfect environment for young roots. Grodan plugs have excellent uniformity, strength and shape that provides the perfect basis for optimum germination and uniform seedling results.The uniformity and reliability of Grodan plugs provide a solid basis for automatic or manual processing, uniform germination and a crop that can be transplanted successfully.Grodan plugs have a uniform density, firmness and fibrous structure. This means that distribution of water, nutrients and pH-value is also uniform, which has a beneficial effect on germination results. Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. 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.
