Properties of rock wool: rock wool is made of 60% diabase, 20% limestone and 20% coke, melted at 2000 ℃ in a high temperature furnace, sprayed into filaments, pressed, cooled to about 200 ℃, added with phenolic resin, and then further processed.

Rock wool is an inert matrix with stable chemical properties. At the initial stage of use, pH > 7, and an appropriate amount of acid can be adjusted. Due to high temperature treatment, it is sterile and non-toxic, with a unit weight of 0.08-0.1, light texture, porosity > 96%, good air permeability, strong water absorption and excretion.

Advantages of rock wool Cultivation:

1. Rock wool is a very excellent substrate in soilless cultivation. In theory, rock wool can cultivate any plant. It is widely used in the cultivation and seedling raising of flowers and vegetables

2. As rock wool itself is a chemically inert matrix, it does not absorb any nutrition and water. Nutrients directly reach the crop root through rock wool, which can easily and quickly adjust the fertilizer concentration and control EC and pH.

3. High quality rock wool is light, porous and breathable, the internal gap distribution is scientific and reasonable, the water and air are evenly distributed, and the plant roots are easy to penetrate, which fully ensures the healthy growth of roots.

usage method

First soak the rock wool block in the nutrient solution and then sow the sterilized seeds. When the seedlings grow to 15-25cm, they can be transplanted into the soil together with the rock wool.
