Material and construction This plant trolley is made of thickened PP+ resin, providing strong durability while remaining lightweight and in strength. Design and compatibility Longlasting, sturdy trays are suitable for potted plants indoors or outdoors. Weather conditions are not a concern for these plant saucers. Indoor trays are without holes, and pebble tray options are available for indoor use. Mobility and placement Indoor plant stand is tall and round, with attached 360degree casters for easy movement of pots, vases, and potted plants. Note: the wheels are not locked. Drainage and maintenance Each plastic plant caddy includes drainage holes. The drain pan is easy to pull out for individual cleaning. The pan catches water to prevent the floor from getting wet when watering, and air can flow beneath the pan to keep the area clean and watertight. Use scenarios 1) Move houseplants between window light and seating areas in living rooms or sunrooms without lifting heavy pots. 2) Use on patios or balconies where weather resistance protects the tray while keeping floors dry during watering. 3) Reposition office or hospitality plants for visibility and workflow, with easy relocation of pots and vases.
