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 over- or 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.
