Vegetable media cubes from Stenewool, plant cubes, soil-free substrate, seed rocks, seedling block, 25x25, 50 wool plug

Made from molten rocks, spun into cotton candy fibers, then pressed into cubes. After high-temperature treatment, it is non-toxic and sterilized. Large density, small, lightweight texture, and high porosity. Good ventilation, strong water absorption, and good drainage. Suitable for planting and colonizing all kinds of plants. An excellent choice for soilless cultivation. Materials: Rock wool. Product usage instructions: Preparation and planting in rock wool blocks. Soak in water for 2 minutes. Remove from water and let sit for 15 minutes. Place seeds in the holes of the cube. Spray water after sowing. Place in a seed tray. This method can avoid diseases and pests during the seedling stage, shorten the seedling age by 3-5 days, and increase the yield by more. Additionally, it is low-cost, labor-saving, easy to transport, and easy to manage. It can also be used for seedling production in field cultivation and factory production for soil plant cultivation. Do not water for 3-7 days before transplanting to dry the rock wool cubes and promote seedling hardening. After roots are fully grown, transplant them with the rock wool into the soil. Water 2-3 days after planting. Compared to traditional planting, this method can make seedlings disease- and pest-free, with no slow seedling period after transplanting, increasing the yield. It is suitable for transportation and management, requiring only watering with a nutrient solution, without measures like soaking, drying, or crouching.
