Use this Hydrofarm GCTC 4-foot tomato tower to keep your tallest climbing plants upright for a bigger, cleaner harvest. The cage design supports plants without blocking sunlight or rain. The four included plastic rings can be added as the crop grows taller. This cage is designed to fit into the Hydrofarm Tomato Barrel, but it can also stand alone in your garden. At season's end, the tomato tower folds flat for easy storage. Tomato Barrel sold separately.
