This air layering propagation ball helps plant branches take root quickly and complete reproduction. Green plant stems and tree branches can grow into new plants efficiently. STRONG FAST RESULTS: The plant root growing box features a cutting globe design that helps cuttings develop stronger roots, enabling faster reproduction of mature plants compared to traditional propagation methods. Propagation results can typically be seen within 1–6 months after installation. SECURE LOCK: The grafting rooting growing box includes plugs and corner locks that interlock and secure the device onto branches. It remains stable even without support rods, though plastic ties can be used to further secure the shells. NO DAMAGE: The rooting device does not harm the parent plant, as it only uses a small branch for cloning, causing minimal interference and not affecting the plant’s natural growth. REUSABLE: The propagation ball is made of durable PP plastic and can be reused multiple times, allowing you to clone various plants as desired. Available sizes: S - 5 cm M - 8 cm L - 12 cm Package includes: 10 x plant rooting grow boxes
