• Your initial Tower Garden purchase comes with 1 quart of Tower Tonic, which makes 100 gallons of nutrient solution for your Tower Garden—enough to supply a typical Tower Garden for 8 weeks.
  • The amount of nutrient solution (water + Tower Tonic) your Tower Garden will consume will vary, depending on the plants you are growing and the conditions you are growing them in. For example, the larger your plants get, the more water and nutrients they need. During the hot summer months, you can actually add fewer nutrients.
