Abstract: Preliminary experimentation has indicated that soilless culture media made of local materials in Suriname are cost effective in lettuce production when using a non-circulating hydroponic system. Furthermore, the use of rice hulls as a soilless media with mineral solutions of either Miracle Growth (18-18-21) or Pokon (6-3-6) as nutrient solution has enhanced lettuce production under greenhouse conditions. In this study three lettuce varieties were evaluated on rice hulls utilizing either Miracle Grow or Pokon as a mineral solution in a non-circulating hydroponic system. Results revealed that the average plant weight of Trinity Star was significant higher (p< 0.05) in comparison to the average plant weight of Black Seeded Simpson and Great Lakes 366. Data also showed that the average plant weight of all three lettuce varieties was significantly higher (p< 0.05) when Miracle Grow was used. The pH of the Miracle Grow solution was significantly higher than the pH of Pokon while the EC of Miracle Grow was slightly higher than the EC of the Pokon solution.
