This is for one sheet of rockwool with 50 plant sites.

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. 
Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.

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. 

A'OK plugs come in a sheet that fits a standard 10x20 flat.

 

A-OK Starter Plugs usage

 

All Grodan stonewool should be pre-conditioned before using because in the manufacturing process, a very small amount of garden lime (pH 8) is added to the binder in the making of the fibers. For this reason a presoak in water adjusted to pH 5.5 is recommended.


Flush to waste with nutrient solution, then plant. This process will wash out the lime leaving the rockwool no longer under its influence to the pH. As the plants grow, the pH will rise (only once the plant is rooted). This is a natural response to the plant consuming the nutrients. Keep pH of nutrient solution between 5.5 and 6.0, ideally around 5.8pH, for optimum nutrient availability.
