Styrofoam ice trays were used to grow `Discovery Yellow' marigolds transplanted 4 weeks after seeds were germinated and then grown in two nutrient cultures. The cultures were Hoagland at the rate of 1/2 ml/6 gal water and nutraculture (20-10-20) at 2.4 ozs/6 gal water. Half containers were aerated and other half were not aerated. Data collected were root, stem, bloom fresh and dry weight, and stem length and number of blooms and leaves. Results showed that stem length, and number of leaves and blooms were significantly greater when grown in Hoagland solution. Fresh and dry weight of roots, stems, and blooms were significantly greater when grown in Hoagland solution. Nonaerated treatments performed significantly better than aerated treatments for either hydroponic solutions.
