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 is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages.
It has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth.
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.
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. Whether sowing or transplanting, the new plug is the solution to achieving a homogeneous sowing result.

Improved homogeneity
Optimum robustness and flexibility
Ideal air/water balance
Consistent shape of the seed hole
Identically shaped plugs
Root development through the entire plug
A’OK plugs are designed for seed and cutting propagation prior to “blocking on” into larger growing blocks. The V-shape design of the plug discourages tangling of roots between the plugs in the A’OK plug sheet.

Single size: about 25x25x40mm/9.84*9.84*15.75in
