This document summarizes an experiment conducted by Sandra Cash and Hannah Peterson to compare plant growth using hydroponics versus soil. They hypothesized that plants would grow better with hydroponics as it allows for more control of nutrient levels. They grew purple daisies for two months, with half in soil and half in a hydroponics kit. The results were inconclusive, as half of both the hydroponics and soil plants died. The surviving hydroponics plants grew slower than the soil plants. More research is needed to make a clear conclusion.
