Description The Yo-Yo pulley for plants serves to guide our plants as well as hold the branches of the plants. The Yo-Yo pulley to hold plants is a tool specially designed to strengthen flowers and plants that cannot stand upright due to their own weight. HOW DOES THE YO-YO PULLEY WORK? The Yo-Yo pulley is a revolutionary system that works thanks to a hook and a retractable rope that retracts automatically and keeps the branches stretched You just have to suspend the Yo-Yo from the greenhouse and catch the stem of the flower with the small plastic hook. The Yo-Yo rolls up as the plant grows and you don’t have to re-hook every few days.
