Our Mini Tomato Tubs are great for dwarf determinate varieties such as Patio, Tiny Tim, Tumbler Toms, Husky Reds. With these your watering will be less often. You can also grow larger determinate types such as Celebrity but you will have to water more often. With the mini tubs you can water from the top but give them just enough to fill the reservoir without overflowing and losing nutrients. 8-8-8 fertilize works great or you can grow organic with organic fertilizers.
