Hydrofarm’s self-watering tomato planters provide lightweight, strong support for tomatoes, beans, peas, cucumbers and other climbing plants and flowers. Use with any potting soil or coco planting mix and the easy-fill reservoir system delivers water and nutrients from below, helping avoid over or under watering. The sturdy frame construction help support the weight of 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.
