The Vevor hydroponic grow system kit features a 3-tier design with 108 planting sites for efficient indoor or greenhouse growing. Its timed irrigation system uses a 4W water pump and 24-hour timer to help circulate nutrient-rich water automatically. Black-and-white UPVC pipes are designed to reflect sunlight, block light intrusion, and help reduce algae growth. Pre-glued connections and included installation accessories make setup easier and more secure. This soil-free system is well suited for growing lettuce, herbs, fruits, and flowers.
