Grodan Improved Pro Starter Mini Block 1.5'' | Unwrapped 2250 per case

Grodan Pro Starter Mini Block 1.5" for Precise Propagation

Engineered with advanced wetting technology, Grodan Pro Starter Mini Block 1.5" provides consistent water content and EC throughout each block to accelerate root initiation and improve uniform growth. Each unwrapped strip contains 45 blocks—50 strips per case—for efficient bench-level handling and high-volume starts.

Perfect for germination and early vegetative stages, the 1.5" format fits standard trays and transitions smoothly into larger blocks or media for continued growth.

Stone Wool Starter Blocks with Advanced Wetting Agent

The hydrophilic, optimized fiber structure ensures full saturation without dry spots, enhancing re-wettability and giving growers precise steering over irrigation and nutrient programs.

Uniform Water Distribution for Strong Root Systems

Consistent moisture distribution supports a dense, well-defined root zone with greater capacity for water and nutrient uptake—translating into robust, vigorous plants.

Durable Structure for Fast Rooting and Easy Handling

These starter blocks maintain firmness and shape through the propagation phase, allowing rapid nutrient solution replenishment and clean, repeatable workflows in trays, benches, and hydroponic setups.

Key Features:

• Optimal Fiber Structure: Carefully engineered to ensure crop uniformity. The fiber structure promotes even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the block.
