In general, you should mix 20 mL of Mineral Blend A and 20 mL of Mineral Blend B with each gallon of water you add to your Tower Garden reservoir. But there are a couple of exceptions:

  • For a Tower Garden full of small seedlings, use half-strength nutrients (i.e., 10 mL of A and 10 mL of B per gallon of water). After about three weeks, you can increase the solution to full-strength.
  • During hot months—when the water evaporates from the reservoir more quickly—use half-strength nutrients (or add full-strength every other time you fill the reservoir).
