Rockwool - Delta Grow Cubes Tub 5L

Delta Rockwool cubes are premium, sterile hydroponic growing media made from spun basalt and chalk, designed for superior plant propagation, rooting, and uniform growth. They offer an ideal air-to-water balance.

Key Features of Delta Cubes:

• Uniformity: These blocks ensure consistent moisture content and nutrient distribution, allowing for even plant growth.
• Sizes: 1 x 1 x 1 cm.
• Structure: They allow for strong root expansion throughout the entire block.
• Preparation: Rockwool typically has a high pH and requires pre-soaking in pH-adjusted water (usually around 5.5 - 5.8) to stabilize and ensure optimal plant growth.

Common Uses:

• Propagation: Used for germinating seeds or rooting cuttings, often fitting into standard trays.
• Hydroponics: Ideal for drip irrigation systems, providing both stability and excellent water/air holding capabilities.
• Transplanting: Once roots emerge, these cubes can be transplanted into larger containers, such as rockwool slabs or soil.
