You will need to prepare the three nutrient solutions for this experiment. The first solution is a pre-mixed nutrient solutions or the standard solution previously listed. Use twice the recommended amounts of nutrients in the second solution. For the third solution, use one-half the recommended amounts of nutrients. You will probably not want to prepare 25 gallons of each solution. The amounts of salts and water may be reduced by one-half, one-fourth, or even more, as long as you mix the proper proportion of ingredients for each of the three solutions.
Be sure to grow the same kind of plant in each container so that you can compare results between the plants. If you transplant into these containers, choose plants that are uniform in size. By varying the nutrient and pH levels and observing the effects of these changes upon the plants, you can determine the proper pH and nutrient levels for a particular plant.
