Introducing the Round Rockwool propagation plug, designed to provide optimal moisture retention while maintaining a lightweight structure. These plugs are perfect for propagating cuttings, as they significantly accelerate root development compared to traditional plugs. Within a matter of days, cuttings effortlessly penetrate the plug with vigorous, white roots, thanks to the unique structure of the stone wool material, allowing roots to spread throughout the plug. Moreover, these plugs effectively retain moisture and release it to the cuttings as needed, ensuring their vitality during transportation or storage, and promoting rapid root establishment once planted in the growth or flowering area. Suitable for hydroponic systems, as well as soil or coco cultivation.
