Hydrofarm's self-watering planters offer robust yet lightweight support for tomatoes, beans, peas, and various climbing plants and flowers. Featuring an easy-to-fill reservoir system, these planters deliver water and nutrients from beneath the soil, effectively mitigating the risks of both overwatering and underwatering. The sturdy frame construction ensures reliable support for the weight of growing vines, enabling plants to channel more energy into fruit development while preventing premature fruit detachment. The expandable trellis reaches heights of over 3 feet, providing ample space for plant growth. Each planter includes a square base, 3 support rings, and 3 connecting risers, with interior dimensions measuring 10" x 10" x 8".
