Grodan Gro-Block Improved GR32 Hugo 6" x 6" x 6" (64/Case)

The Grodan Gro-Block Improved GR32 Hugo 6" x 6" x 6" (64/Case) is a large professional stone wool growing block designed for hydroponic cultivation, established plants, and precision root-zone management.

Each GR32 Hugo has nominal dimensions of 6 × 6 × 6 in, with technical dimensions of approximately 15 × 15 × 14.2 cm, providing about 3.2 L of stone wool substrate. Each block includes a planting hole for compatible rooted plugs, and each case contains 64 blocks.

Key Benefits

  • Professional Grodan improved stone wool block.
  • Nominal dimensions: 6 × 6 × 6 in.
  • Technical dimensions: approximately 15 × 15 × 14.2 cm.
  • Approximately 3.2 L of substrate per block.
  • 64 blocks per case.
  • Integrated planting hole.
  • Large root-zone volume.
  • Uniform water content and EC distribution.
  • Good moisture buffering capacity.
  • Compatible with drip irrigation and precision fertigation.
  • Suitable for established plants and full-cycle cultivation.

Why Choose the GR32 Hugo?

The GR32 Hugo provides a substantially larger root zone than smaller Grodan blocks.

Its approximately 3.2 L substrate volume gives roots more room to develop while providing a greater water and nutrient buffer. This makes the Hugo especially useful for growers who want to cultivate larger plants in an individual stone wool block.

Grodan Improved Technology

Grodan Improved Technology combines an optimized fibre structure with advanced wetting technology to promote more uniform distribution of water and EC throughout the block.

This helps improve control over irrigation frequency, nutrient delivery, water content, and dry-back throughout the crop cycle.

Large Root Zone for Precision Growing

The Hugo’s larger volume provides more moisture capacity than compact Gro-Blocks while still allowing precise irrigation steering.

Its format is suitable for growers looking for a stand-alone block with enough volume to support established plants without immediately moving into a larger slab system.

Ideal Applications

  • Hydroponic cultivation
  • Drip irrigation
  • Precision fertigation
  • Indoor horticulture
  • Commercial greenhouses
  • Controlled-environment agriculture
  • Established plants
  • Flowering and fruiting crops
  • Individual root-zone management
