Are wet and dry the correct terms to use when describing rockwool?
The answer is no, but often we use them to simplify explanations. Citing the question above about horizontal and vertical is the perfect example. The only difference between a given manufacturer s horizontal and vertical growing slabs is the orientation of the cut when the raw material is made into horticultural product. The starting material is exactly the same. How could the exact, same material be wet in once instance and yet dry in another? Professor van Hydro would very much like to see this misleading terminology disappear from the scene, but alas, there are some who prefer to perpetuate the myth.
