    Effects of substrates on plant growth in a raft aquaponic system
    (2015-05) Sorensen, Marie; Roth-Krosnoski, Thomasina; Robinson, Laura
    As the popularity of aquaponics increases as a method of sustainable food production, best practices continue to be refined. Additionally, rules regarding organic certification of aquaponics facilities are vague or nonexistent. Rockwool, a substance commonly used in production is not currently allowed by the Organic Materials Review Institute. The purpose of our research was to determine if an organic substrate such as coconut coir, lava rock or expanded clay aggregate (ECA) could produce yields comparable or exceeding that of rockwool. Materials for comparison were chosen based on their availability or affordability.
