This rockwool grow cubes is made from natural rock by high temperature melting, spun into fiber, and then compressed into 25x25x40mm soft cubes, blocks, or slabs. Under the super high temperature, it is an Inorganic & Sterile growing medium
The bulk density is small, the texture is light, and the porosity is large, water and air are evenly distributed. The nutrient solution reached the root system of the crops through rockwool, good for plant growth. The water absorption rate of mass is above 800%. Water, fertilizer performance is good. No other devices are needed during cultivation
Great for rooting, cuttings, clone plants, germination start seeds and more. Strip, block for easy handling, can also be transplanted. Vegetables and flowers grown with rockwool, high yield, good quality, less pollution
Graduated Sizes - Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the cubes can also be transplanted into more traditional and growing mediums.Growing Medium Starter Sheets Rockwool Starter Cubes for Seedling Propagation,Cloning.
