Feature Advantage:
  • Superior Water Absorption for Hydroponic Systems: The rock wool plug features strong capillary action, rapidly absorbing nutrient solution and distributing it evenly, ensuring consistent moisture around the root zone and preventing localized drying or hypoxia.
  • Structural Support for Upright Growth: The 40*40mm size provides adequate mechanical support, helping leafy greens maintain an upright posture, which improves light exposure and space utilization in high-density cultivation.
  • Inert Medium for Precise Nutrient Control: Chemically stable, the rock wool material does not interfere with nutrient solution composition, allowing precise adjustment of nutrient formulas for standardized, data-driven hydroponic production.
  • Seamless Transition from Nursery to System: Seedlings can be started in the same size rock wool plugs and transferred directly into hydroponic systems without removing the medium, minimizing root disturbance and reducing transplant shock for uniform growth.
