Design and Fabrication of a Pyramid-Type Plant Bed Hydoponics of Romaine Lettuce Production under Lowland Condition
Keywords:design, fabrication, hydroponics, prototype, area utilization efficiency
AbstractThis study aims to design and fabricate a pyramid- type plant bed hydroponics under lowland, open-field condition. The hydroponics system recirculates a total volume of 150 liters of nutrient solution with an average flow rate of 33.33 milliliter per second and was designed to hold a capacity of 100 plants with 20 cm spacing. The fabricated pyramid-type plant bed hydroponics has an area utilization efficiency of. 169.49 percent. The prototype was tested on romaine lettuce. A commercial liquid bio-fertilizer was used as a liquid solution in the study with a concentration of 1:100. However, the plants only lasted for 15 days and had no significant yield. The newly designed hydroponic grow bed system is recommended for further evaluation considering the nutrient requirement of the test plants.
