Blueberries are one of the most nutrient-dense foods in the world, containing vitamin C, vitamin K, manganese and a broad range of antioxidants.

In my answers I frequently refer to the root zone solution. That is, the solution around the plant roots from which the plant takes up water and nutrients, as explained in my previous two columns. I stress that it is this root zone solution, which is the basis for good hydroponic management. Many growers obsess about their feed solution, but this is only a means to managing the root zone. I am often asked how to collect a root zone solution sample from a dripper-fed container of medium, so this is my practical answer to that question.
