In modern greenhouse horticulture, precision growing is based on understanding what happens inside the substrate. Measuring key root zone parameters such as water content (WC), electrical conductivity (EC), and pH allows growers to gain direct insight into plant conditions and make informed decisions throughout the cultivation cycle.
While monitoring irrigation input provides useful information, it does not fully reflect what is happening in the root zone. By measuring directly in the substrate using dedicated sensors, growers can gain real-time insight into water distribution, nutrient availability, and overall root zone conditions. This allows for more accurate adjustments and improved control over the cultivation process.
Monitoring root zone conditions provides several important benefits. It allows growers to optimize irrigation and fertigation strategies, improve plant performance, and reduce variability across the crop. Continuous data collection also enables better decision-making, helping to prevent issues before they impact plant health. In addition, more precise control can lead to more efficient use of water, nutrients, and energy within the greenhouse system.
Measuring the substrate gives growers the information needed to make informed decisions about irrigation and nutrient management. Without direct measurements, adjustments are often based on assumptions rather than actual plant conditions.
In addition, monitoring helps prevent the accumulation of unwanted elements in the root zone, which can lead to imbalances and reduced plant performance. By tracking changes over time, growers can respond quickly and maintain stable conditions.
Accurate measurements also contribute to more efficient resource use, reducing unnecessary water and fertilizer application and supporting more sustainable production.

Caramet sensors of SenseNL are specialized root zone sensors that can be used to measure WC, EC, and temperature directly in the substrate. For consistent results, sensors should be placed at a fixed position within the stone wool. Using multiple sensors across the growing area helps reduce variability and provides a more complete picture of root zone conditions.
Based on the data collected, growers can make targeted adjustments to irrigation and nutrient strategies, improving plant performance and reducing the risk of damage caused by sudden changes in the root zone.
Understanding what happens inside the substrate is essential for successful stone wool cultivation. By measuring key parameters such as water content, EC, and pH directly in the root zone, growers can move from reactive to data-driven decision-making.

In professional greenhouse horticulture, growers often perform side-by-side trials to evaluate which substrate best supports their crop and cultivation strategy. A well-designed trial improves decision-making and helps identify the most efficient and reliable solution for consistent production.

There are many aspects affecting the decision of which substrate to use, among these crop types and cultivation stages. Similarly to the way soil mixtures can be amended and customized, so are stone wool products tailor-made for the cultivation of a specific variety of crops. Stone wool can be manufactured in such a way that the density and orientation of the molten rock fibers determine the moisture holding capacity, air-filled porosity, and moisture gradient within the blocks.

From a young age, we were taught not to try to fit a square into a circle. Child games utilizing different shapes emphasized this even more with specific shaped objects only fitting in the same shaped hole. And thus comes one of the most common stone wool questions we get. Why do people use a square propagation plug (AO) when the hole in the block is round? Well, there are a couple of different reasons why one might choose to use either a square Cultiwool plug (AO) or a round Cultiwool plug (i.e., macroplug). This article will elaborate on these reasons;
