Rock Wool Growing Slab 6 Openings 900×200×75mm

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.

• 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
