Founded in Europe in the 1970s, rock wool cultivation is increasingly popular with growers around the world for its advanced planting properties. But rock wool cultivation started late in China, the research and development of SunPlus aims at providing growers with much safer, greener, more precise and efficient planting substrates to accelerate the pace of modern agricultural development, improve modern agricultural production efficiency, reduce resource consumption and promote sustainable development of modern agriculture.
The application of SunPlus substrates helps to accurately control the nutrients and water content that the plants need in each stage of growing, improve the utilization rate of fertilizer and water, shorten the growth stages of plants to come into season much earlier and greatly increase yield with excellent fruit quality.
SunPlus rock wool substrate is suitable for greenhouse farming, floriculture, herbs medicine growing, three-dimensional greening, planting walls and home gardening etc.
Sterile: Rock wool cubes are sterile and inorganic. After being exposed to extreme heat, Rock wool arrives at a grower’s doorstep clean and ready for use. Because it doesn’t contain any organic matter, Rock wool helps to protect the root zone against damaging microbes.
Compostable: Although they take a long time to break down, growers can shred their used blocks down as finely as possible and throw them onto the compost pile. Over time, key elements within basalt rock will leach into the compost and add a nutritional kick to your future soil.
Good drainage: Rock wool cubes become saturated with water when you soak them, but it quickly drains away. Each cube contains many small spaces between the fibres that help to effectively drain water. Overwatering kills many grows before they even get started. Damp conditions can foster fungal pathogens that quickly destroy seedlings. Although Rock wool cubes are largely safe from microbes, excess water can still suffocate roots and hamper growth. Good aeration stops this from happening.
Great for germination: Rock wool cubes provide a haven for seeds during germination. By keeping them sufficiently saturated, they provide the three key demands required for successful germination: darkness, moisture, and warmth.
Easy Root Penetration: Sometimes seeds struggle to become established when sown in compact and hard soils. However, they establish themselves quickly and easily within rock wool cubes. The young roots easily pass through the gaps between the fibers.
Easy To Transplant: Once your seedling looks ready for a new home, you’ll find it incredibly easy to move it directly into a pot full of soil or a hydroponic net pot. Unlike transplanting from soil, you don’t need to break apart the initial growing medium or deal with any mess. Simply pick up the cube and slot it into its destination.
