Cultiwool stone wool is the growing media of choice for growers looking to grow a healthy and uniform crop. Stone wool is made from rocks such as basalt and anorthosite. The rocks start to melt around 1,600°C (2,912°F). From the liquefied rock, fibers are spun and specialized binders as well as wetting agents are added, resulting in large boards of Cultiwool stone wool.

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;

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.

The global demand for healthy, safe, fresh, and local produce has been rapidly increasing. Among many things, it requires nutritious produce and a sustainable approach to cultivation. Sustainability can be defined in several ways, but an Important one is reduction of the carbon footprint and/or use of resources such as water and fertilizers. As water scarcity is becoming more pronounced and soils turn more saline, optimal use of water is required as well as reducing emissions into the environment becomes a necessity and a daily task for growing businesses. Horticultural approaches offer a wide variety of applicable cultivation systems, from which substrate choice is leading in water and fertilizer use efficiency.
