Description
Rock Wool Growing Slab / 6 Openings / 900×200×75mm
Product Description

This rock wool growing slab is specifically designed for long-season flowers, e.g. cut rose, cultivation, measuring 900×200×75mm with 6 equally spaced planting openings on the top. Designed for soilless greenhouse production of cut roses, a single installation lasts 6-8 years without replacement. The rock wool fibers are specially treated for enhanced durability, with significantly improved compression resistance and anti-aging properties, maintaining structural stability under long-term wet conditions and root pressure. The 6-opening high-density layout matches the multi-stem growth habit of roses, enabling high-yield, uniform, high-quality cut flower production.

Applications
  • Long-season cultivation of greenhouse cut roses (red, pink, white, spray roses)
  • Mother stock blocks for rose propagation (donor plants for cutting propagation)
  • Long-term soilless cultivation of perennial woody flowers (chrysanthemum, carnation)
  • Introduction and acclimatization of high-end rose varieties and seedling propagation
  • Permanent planting of grafted roses
  • Long-term single-plant observation and selection in rose breeding nurseries

Key Features
Ultra-long service life (6-8 years): Special fiber curing process reducing tearing damage of substrate caused by tall plants. One installation supports multiple consecutive harvest cycles, significantly reducing replacement costs and labor intensity.
6-hole dense planting layout: 150mm spacing matches the multi-stem branching habit of roses, achieving high cut flower yield.
Stable pH and low initial EC: Neutral to slightly alkaline rock wool with initial EC ≤0.3mS/cm, safe for delicate rose roots; pH buffering capacity remains stable during long-term use, reducing acid adjustment frequency of nutrient solutions.
