★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.
★It 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 cubes can also be transplanted into more traditional planters and growing mediums.
★It is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Single size: about 25x25x40mm/9.84*9.84*15.75in.
★It has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Whether sowing or transplanting, the new plug is the solution to achieving a homogeneous sowing result.
★The renewed plugs result in a maximum number of useable and homogeneous seedlings. Both form and strength have been greatly improved for good machine and manual processing.
