STRONG & FAST RESULTS - This is especially created with a cutting globe design which helps your cuttings achieve stronger roots to reproduce a more mature plant faster than normal propagation methods. It allows you to see propagation results within 6-8 weeks after installation. SECURE 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.
