Product Description

Tomatoes Growing Greenhouse Hydroponics 4" Rock Wool Cubes

Optimal 4"x4"x4" Dimensions

Advanced Wetting Agent Features
• Enhanced initial saturation capability
• Optimized water distribution throughout the block height
• Uniform water content (WC) and electrical conductivity (EC) across the entire block
• Rapid and efficient WC/EC adjustments
• Improved water retention and root-zone EC behavior

SOAKING GUIDELINES

1. Initial Saturation: Soak the block with pH 5.5-6.5 water for cuttings.
2. Transplanting: Use nutrient solution equivalent to the plant's pre-transplant feeding strength.
3. Full Immersion: If submerging, maintain until air bubbles cease.

 

IRRIGATION PRACTICES

• Drip Systems: Use one drip stake per block; keep moist, not saturated.
• Ebb & Flow: Irrigate when the block reaches ~50% of saturated weight.
• Manual Watering: Maintain moderate moisture; avoid oversaturation post-initial soak to prevent growth delays.

 

TRANSPLANTING STEPS

1. Insert rooted rock wool cuttings into the block's hole.
2. Withhold watering for 2-3 days until roots establish (avoid complete drying).
3. Lightly mist daily if needed; prevent water pooling around blocks.

 

TRANSPLANTING FOR LARGER PLANTS

• Short-term crops: Use blocks alone.
• Larger plants: Transfer blocks to rock wool slabs, loose media, or soil.
• Pre-transplant Check: Ensure roots visibly emerge from the block base.
• Post-transplant: Saturate the new medium thoroughly during relocation.

Stone Wool: The Pinnacle of Horticultural Excellence

Stone wool, also known as rockwool, stands as a paragon of purity and inertness in the realm of horticulture. Crafted from volcanic rock, this high - performance growing medium is a testament to innovation, meticulously engineered to provide plant roots with the perfect equilibrium of water, air, and nutrients.

 

Its clean composition ensures a sterile environment, free from contaminants that could impede plant growth. As an inert substance, stone wool remains chemically stable, neither altering the pH of the growing solution nor interacting unpredictably with fertilizers. This stability creates a consistent foundation for plants to thrive.

 

The unique structure of stone wool allows it to strike an unparalleled balance. It retains just the right amount of water, ensuring plants never suffer from dehydration, while simultaneously providing ample air pockets for roots to breathe. Moreover, it serves as an efficient carrier for essential nutrients, delivering them directly to the root zone in a readily - available form. In essence, stone wool transforms the growing process, offering growers a reliable and high - performing medium that maximizes plant health and yield.
