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 doesnt disturb the plants 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 hearts content.
