Cultiwool CRB Trays
Cultiwool CRB Trays provide a premium-quality rooting environment designed for fast, uniform germination and strong early plant development. Each tray is filled with high-grade stone wool plugs produced using the same advanced fibre-spinning technology found across the Cultiwool range, ensuring consistent density, excellent water retention, and optimal aeration.
Fully inert and sterile, Cultiwool CRB Plugs give young plants a clean start free from pests, pathogens, or contaminants. Their uniform structure allows for even hydration throughout the tray and encourages dense, healthy root formation—ideal for growers using hydroponics, aeroponics, or traditional soil blends.
Ready to use straight from the pack, these trays make propagation simple and reliable, whether you’re germinating seeds or rooting cuttings. Once rooted, plugs can be transplanted directly into rockwool blocks, coco, or soil with minimal stress.
