Bachelor of Science in Agricultural Engineering, Cavite State Univesity, Indang, Cavite. April, 2003. Adviser: Engr. Cesar C. Carriaga. A study was conducted to design and evaluate a low-cost hydroponics system for lettuce production. The study aimed to: a) assess the performance of lettuce grown under a low-cost hydroponics system; and b) conduct a cost and return analysis of the system. A low-cost hydroponics system with a planting area of 5.4 m2 was used in the study. The system was composed of three layers which made up the set- up, half for using the foam as holder of the plants and the other half for using the mixed charcoaled rice hull, coir dust, and compost as artificial medium. Based on the results of the study, it was observed that lettuce grown with foam holder were shorter than those planted with mixed charcoaled rice hull, coir dust and compost as holder. Lettuce grown with mixed charcoaled rice hull, coir dust, and compost as root holder produced more number of leaves, higher yield and had final root length compared to those grown in foam as root holder. A plant grown in foam as holder has a net income of P 21.99. On the other hand, a net income of P 130.46 was obtained for plants grown in mixed charcoaled rice hull, coir dust, and compost as artificial mediums
