Environmental control: reduces the temperature difference between day and night and maintains the temperature of the root. The moisture condition of each rock wool is also similar. Convenient to use: the plant stakes can sow directly, simplify the seedling process, save time and physical strength. Beneficial to the root system: A plug for a seedling promotes the growth of the root system of the seedling. Good Manufacture: made of fibers that are spun into sugar-like fibers and then pressed into cubes. For easy sowing: the rockwool plugs can be used for large batches of seedlings and also for family seedlings. The seedling cycle is short, comfortable, fast and efficient.
