Supports Up to 15 Plants The WS-6 watering system is perfect for indoor gardens, balconies, or patios, efficiently managing up to 15 potted plants. To ensure even water distribution, make sure the drip irrigation tubes for all pots are set at roughly the same height. With a flow rate of approximately 18.6 fluid ounces per minute, adjust the number of drip and watering frequency based on your plants’ specific water needs. Note: Ensure the water source is positioned below the entire watering system for optimal functionality.
