Cultiwool Prime Growing Blocks
Horizontal Fibre Block for Stable Root DevelopmentPrime Growing Blocks is developed for growers who prioritize stability during the transplant phase. Its horizontal fibre structure distributes and retains water more evenly, creating a buffered root environment that supports consistent plant establishment and reduces sensitivity to irrigation variations. Cultiwool Prime is made with a natural plant-based binder, helping to create a stable root zone that supports strong and uniform plant development.
Stable Establishment & Moisture Balance
Produced using natural binder technology, Cultiwool Prime Growing Blocks offers a uniform substrate with enhanced water-holding capacity and a balanced air-to-water ratio. This supports steady root development, consistent nutrient availability, and reduced plant stress during the critical early growth phase.
