Crafted from a base of basalt and limestone, the 5cm Rockwool Cube – 6 Pack provides superior quality and performance for hydroponic cannabis growers. Heated to 1500°C and spun into fibers, this rockwool contains only 5% rock content, ensuring exceptional capillary action for the roots while retaining sufficient water for growth.

Key Features:

  • Superior Water Retention: Low-density rockwool provides excellent capillary action, keeping roots hydrated and promoting healthy growth.
  • Completely Inert: Rockwool will not buffer pH levels or degrade into soluble parts, maintaining a stable growing environment.
  • Ideal for Hydroponics: Designed for hydroponic systems, ensuring optimal conditions for cannabis cultivation.

Usage Instructions:

  1. Preparation:
    • Before use, soak the rockwool cubes in a light nutrient solution that has been pH adjusted to 5.2-6 for 24 hours. This ensures the cubes are properly hydrated and ready for planting.
  2. Planting:
    • Insert your cannabis seed or cutting into the prepared rockwool cube. Place the cube in your hydroponic system, ensuring it remains moist and receives adequate light.
  3. Ongoing Care:
    • Maintain the pH levels of your nutrient solution within the optimal range for cannabis plants. Regularly check the moisture content of the rockwool and adjust as necessary.
