Product Overview

Manufactured by melting basalt rock and spinning it into fine mineral fibers, our Hydroponic Rockwool serves as an inert, sterile substrate designed for greenhouse propagation and hydroponic cultivation. The fibrous structure retains nutrient solution while maintaining exceptional pore space for oxygen delivery to the root zone. From initial seed germination to mature plant anchorage, our full product line accommodates every stage of plant development.

Key Performance Characteristics

  1. Uniform Moisture Distribution: Maintains balanced EC levels and consistent capillary action throughout the substrate.

  2. Light-Shielded Side Wrapping: Protective outer foil minimizes light exposure to roots, preventing algae development on the media walls.

  3. Seamless Transplanting Integration: Starter plugs fit snugly into pre-drilled holes of larger growing blocks for stress-free root transition.
