    Product description

    Rock wool is light, compact and relatively inexpensive. It has a high water retention capacity and contains a lot of air. Yet it is true that rock wool, for a tropical plant, does have its instructions. A large part of the growers grow too wet. This lowers the absorbable EC. That's fine for a growing plant, but not a blooming one. The PH value of rock wool is quite high, around 8. With rock wool it is therefore important to water well with a low PH (5.1-5.5), especially because the rock wool always has the inclination the PH value in the slab Never set your PH below 5, your plant can handle that, but the rock wool cannot. As a result, it will lose its resilience and collapse. If you treat stone wool well, it will last a relatively long time.
