We supply rockwool substrate solutions. The lightweight hydroculture substrate is available in blocks or slabs. Rockwool ensures a fast and effective distribution of water and nutrients. This allows maximum use of the substrate volume, which will lead to a fast, healthy development of the plant’s rooting system.

As a grower, you continually aim for a good plant balance; the optimal balance between generative and vegetative growth. The EC in the root environment is an important steering tool since it determines whether water and nutrients are easily absorbed. It is logical that you want to keep this parameter under control as well as possible. A good and uniform EC distribution through the entire depth of the substrate is very important. Large differences in EC values​mean that the substrate is used less well because plant roots avoid substrate areas with high EC values. This results in less optimal root distribution and less steerability.
