Stone wool: Unique Product Features of Our Blocks
5 oktober 2022
Tailor made quality
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.
About the benefits
Overall, there are many advantages to using stone wool for many different crops. At Cultiwool we have engineered our products (plugs, blocks - cubes, and slabs) in such a way to fit the cultivation requirement of cannabis. It is important, especially because of the unique aspects of cannabis production; uniformity and hygiene. Whether it is because of genetic instability or varying conditions of growth, uniformity is a key to success and increasing yields for all growing stages, from propagation, to vegetative stage, flowering and harvest. Maintaining a hygienic environment in the cultivation facility is crucial to avoid crop and yield loss. The requirements are high for the quality control and certifications of cannabis production facilities, such as GACP in cultivation and GMP in post harvest. The different products offered by Cultiwool will allow the grower to have accurate, uniform, clean, and more sustainable irrigation and fertilization. These benefits will contribute to the health and balance of the root zone, will play a role in steering towards the vegetative stage or flowering, and generally optimize plant growth and development depending on the used cultivation and irrigation strategies.

At Cultiwool we have worked to improve the products in order to adjust it to the needs of cannabis by using innovative and patented solutions in order to tackle some basic daily challenges cannabis growers might deal with. Introducing the Donut ring and Cross groove technologies.
Efficient water distribution
After initial saturation of the stone wool blocks, it is essential to maintain water distribution even throughout the block to promote healthy and vigorous root growth. Originally one dripper per block was considered the standard, and this evolved into two drippers on opposite sides. However, inconsistencies in root growth were still observed as a result of uneven distribution of water. In order to prevent this and ease cultivation, we developed the Donut ring Cultiwool stone wool; blocks that were engineered with a ring on the upper side of the blocks. At the moment of irrigation, these are filled up, allowing similar rates of nutrient solution to drip into the stone wool bocks. This method of irrigation allows for uniform and efficient distribution and use of water and fertilizers, which result positively affect plant growth.

However, not only the method of irrigation determines water distribution within the blocks. Monitoring the drain has a heavy impact on the health of the root zone, for example, the EC levels. Standard stone wool blocks have a single groove on the bottom through which water can drain out. However, these have to be placed correctly on gutters to allow for them to function as intended. The risk of human error is always present, the cross groove technology of Cultiwool solves this. The cross groove pattern allows for uniform drainage of water from the stone wool blocks, irrespective of orientation, thus promoting regular growth, yield, and flower quality throughout your crop.
The team members of Cultiwool are in constant and direct relationships with the worldwide cannabis industry (suppliers, growers, etc.), as we aim to keep improving our products while contributing to the growers and developing the industry to manage challenges and find solutions for them in innovative ways.

Advanced Nutrient & Crop Steering Techniques in Stone Wool Cultivation
Stone wool has become the preferred substrate for precision cultivation, offering growers unparalleled control over water, nutrients, and oxygen availability at the root zone. As controlled environment agriculture (CEA) advances, one of the most impactful strategies growers can adopt is crop steering. That is a data-driven approach to adjusting environmental and nutritional inputs to guide plant development toward desired outcomes. Whether targeting higher biomass, increased yield, or enhanced quality (such as flavor or cannabinoid concentration), crop steering techniques can transform results in both medicinal and food crop production.
Avoiding the Top 5 Mistakes When Growing in Stone Wool
Stone wool is a powerful and precise substrate that enables growers to fine-tune plant development with unparalleled control. However, with this precision comes the need for accuracy at every step of the growing process. At Cultiwool, we have seen how easily small mistakes can lead to big inefficiencies or lost yields, especially in high-density, high-value crops like cannabis. Whether you are an experienced cultivator scaling operations or just starting with stone wool, here are the five most common mistakes we see, and how to avoid them.
Substrates side-by-side; How Do I Choose the Substrate Best Suited to my Situation?
At Cultiwool, we are frequently approached by growers who want to do a side-by-side of the substrate they are using and Cultiwool. We are happy to facilitate these trials, even provide support on their success. However, there are some common improvements we see across the board that can raise the quality of the trials and improve your decision-making. Therefore, we have written this article to help set up the perfect substrate trial in a facility.
