Each sheet of Grodan Prop Slab A-OK Starter Plugs is perfectly-sized to fit a standard flat and each plug has a pre-formed hole to easily plant seeds and cuttings. Once rooted, you can transfer individual A-OK Starter Plugs to larger pieces of stonewool or plant them directly in soil. For any growing application, rockwool offers speed, ease of use and cleanliness.
Grodan 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. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs. Seedlings or cuttings started in the Grodan Prop Slab 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. A-OK plugs come in a sheet that fits a standard 10×20 flat.
