The Five Primary

Benefits of Stone

Wool

E.C.

The distribution of the water and nutrients in the substrate is important to achieve an even root distribution. Good availability of nutrients for the roots is vital for optimal quality and production. Changing the EC value is also a useful tool for controlling the plant balance  

Oxygen

All parts of the plant - leaves, stems and roots - need oxygen. In the mat, the roots need oxygen for cellular respiration. When sufficient oxygen is present at the roots, the root system can function optimally. Oxygen is also used by microorganisms, fungi and bacteria. In rock wool, especially bacteria, which are present in large numbers a few hours after moistening the rock wool. When conditions are low in oxygen, the microorganisms with the roots can compete for the use of oxygen.

Water Content

The water content of the substrate forms the water buffer and contains the  nutrients for the plant. Changing the water content is a useful tool for controlling the plant balance and maintaining the health of the root system. 

PH

The plant's ability to absorb needed nutrients is affected by the pH of the nutrient solution. This means that it is very important to have the correct pH value around the root system. The image below shows the recording of different elements at different pH values. 

Temp

The temperature of the root zone is not always measured or controllable. It is however very important and root temperatures should be kept between 18 oC and 25 oC. As the temperature of the root zone rises, the availability of oxygen from the irrigation water decreases. At root temperatures above 25 ° C, this, in combination with competition between the roots, can lead to the death of roots, especially with weak root distribution. This opens up the possibility of secondary contamination from root pathogens such as Pythium.

Uniform and Optimally Controllable (EC)

As a grower you continuously strive for a good plant balance; the optimal balance between generative and vegetative growth. The EC in the root environment is an important control tool, as it determines whether water and nutrients are easily absorbed. It is logical that you want to keep this parameter under the best possible control.  It is very important to have a good and uniform EC distribution throughout the substrate. Large differences in EC values ​​cause the substrate to be used less well, because the plant roots avoid substrate areas with high EC values. This results in uneven root distribution and less controllability.

Root Distribution

The right roots distributed in the right way.  As a grower, you attach great importance to the correct distribution of the roots through the substrate mat.  After all: good root distribution contributes to a more uniform and more controllable EC and water content. The fiber structure of the rockwool, among other things, influences the root distribution: in a vertically fiberized mat, the roots will grow directly downwards faster than in a mat that also contains horizontal fibers.  In addition, you want as many hair roots as possible in your substrate.  After all, these play an important role in nutritional uptake.

Water Content Focus on Homogenety

A substrate that can intern a lot, so that you can generatively steer with low water content in dark periods, but where re-saturation is easy; that is what you as a grower want and expect. In addition, you always strive for the most homogeneous moisture distribution. That is easier said than done: gravity causes the water to sink to the bottom of the mat. But also the distribution of the roots and the type of roots influence the water distribution.
