Effectiveness of Compact Hydroponic System in Outdoor Gardening

Abstract

This thesis was born out of the idea to produce green leafy vegetables using a compact hydroponic system. Hydroponics is essentially in growing of plants without the use of soil. Many innovations and designs all over the Philippines are made to increase the production rate and capabilities of the hydroponic system. The main concern of the study was to develop an innovative, fully capable compact hydroponic system that combines currently existing nutrient film technique and Kratky (non-circulating technique) to create a system that can provide a steady supply of nutrients needed for growth and healthy development of plants without the need for specialized greenhouse structures. Data were gathered through experimentation and survey to determine the most durable and available materials to ensure the maximum integrity of the system. Two different techniques and special system design were utilized to create a favorable environment for the fast growth of plants. The effectiveness of the system was tested by determining the average growth of the lettuce plants. The study revealed that the system was able to grow healthy 864 lettuce plants without the use of insecticides and fertilizers. It is recommended to try the system using other green leafy vegetables to prove its effectiveness further.
