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


Grodan
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.



Size for one grow plug : 25x25x40mm
