Hydrofarm's self-watering planters provide lightweight, strong support for tomatoes, beans, peas and other climbing plants and flowers. An easy-to-fill reservoir system delivers water and nutrients from below, helping avoid overwatering and underwatering. The sturdy frame construction helps support the weight of the vines as they grow, allowing the plant to devote more energy to developing fruit—and preventing the fruit from falling off before it's ripe.
