## Description

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.  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

## Features
