This document summarizes an experiment on growing different types of seeds in varying ratios of coffee grounds and soil. The experiment tested ratios of 100% coffee, 100% soil, and mixtures of 20:80, 30:70, 40:60, and 50:50 coffee to soil. Seeds of zinnias, nasturtiums, and basil were planted. The results showed that seeds planted in a 30:70 coffee to soil ratio grew the tallest and had the most root hairs, disproving the hypothesis that a 1:1 ratio would be best. Nasturtiums generally grew the tallest of the three plant types. The conclusion is that coffee grounds can benefit seed development when used in
