Hydrofarm Tomato Barrel & Tower. Grow tomatoes from the ground up no matter your space limits or climate. The sturdy and strong frame construction supports the weight of the tomato vines as they grow lush with fruit, allowing the plant to devote more energy to growth and preventing fruit from dropping off and getting crushed. The lightweight materials, just over 3 lb, make it easy to move. The barrel reservoir system offers an easy to fill way to provide your tomato plants roots constant access to moisture and nutrients and reduces chances of over or under watering. The expandable over 4' trellis can be used to grow beans, peas, and other climbing plants and flowers. This self-watering planter and support tower is ideal for patios, decks, balconies or even rooftops.
