• Growing Sunflowers - Hydroponics vs' Soil
    Experimenter: Sophia Coraci
     
    Problem:  Does Helianthus annuus (common sunflower) exhibit faster growth in traditional potting soil or in a dutch bucket hydroponic system?
     
    Hypothesis: Helianthus annuus will grow taller in a dutch bucket hydroponic system because of the constant supply of fertilizer applied directly to the root system.  
     
    Experimental Design: Helianthus annuus seeds were germinated in traditional potting soil.  After the seeds germinated; 10 seedlings were planted in 4 inch plastic pots using traditional potting soil and 10 seedlings were planted in 4 inch plastic pots using large grain perlite in a dutch bucket hydroponic system.  Stem height measurements were taken over the course one month.
