Features: Plant propagator - Uses the ancient method of Air Layering which is about growing roots right onto the branches to replicate your existing plants and produce a new one. It works on both indoor and outdoor plants like roses, climbers, trees, fruit bushes, fruit trees, and hard to root plants like Camellias. No damage- Provides no damage to the parent plant at all as it only uses a small branch on the plant you want to clone, thus creates little to no disturbance and doesn39;t disturb the plant39;s growing Strong and fast result- This is especially created with a cutting globe design which helps your cuttings achieve strong roots to reproduce a plant faster than normal propagation methods. It allows you to see propagation results within 6-8 weeks after installation. Safety lock- Designed with stoppers and corner locks which interlock with each other and secure on the branch to hold the propagator in place even without a stem underneath. However, you can use plastic ties to hold the shells securely. Reusable - The propagation shells are sturdy and durable enough to be reused over and over again so you can clone more plants to your heart39;s content.
