VIVOSUN FlexFeed 4-Pack Self-Watering Irrigation Pot Bases — 1.3 gal (6L) Reservoir, Water Meter & Maintenance Window, Fits up to 5 gal Fabric Grow Bags, Supports 130 lb (60 kg)

Pack of four VIVOSUN FlexFeed self-watering pot bases, suitable for indoor and outdoor use in grow tents, greenhouses, and gardens. Constructed from high-strength glass fiber-reinforced polypropylene, each base is built to last and can support up to 130 lb (60 kg). Designed to accommodate fabric grow bags up to 5 gal and can be upgraded to a drip system using the FlexFeed Drip Irrigation Kit. Each unit includes a 1.3-gallon (6L) reservoir that consistently waters plants for up to a week, helping prevent both overwatering and underwatering during extended absences. A gridded maintenance window provides clear access for refilling and for pH/EC testing or feed adjustments. Active monitoring is provided by a simple water meter that indicates reservoir level and alerts you when it’s time to add water. An elevated drain plate with multiple drainage holes and grooves lifts the grow bag to prevent pooling and guides excess runoff into the basin below.
