Products Description
Rockwool cubes are composed of mineral wool, a type of insulation material made from molten rock spun into fibers. These cubes serve as a popular hydroponic growing medium due to their excellent water retention and aeration properties. They are commonly used as a substrate for starting seeds or supporting plant growth in hydroponic systems. Rockwool cubes provide a stable structure for root development, ensuring plants receive sufficient moisture and oxygen while being easy to handle and transplant.
Today, we will introduce to you a new kind of growing mediums -- Tenlead Germination Cubes.
Tenlead Germination Cubes are non-toxic, harmless, sterile, pollution-free and other characteristics and good air permeability can be effectively improved through the accurate nutrient solution management system. Crafted from high-quality phenolic foam—a lightweight, porous material renowned for its exceptional water retention and aeration properties—these germinating cubes offer an optimal environment for seed germination and root development.
