Abstract
The design of the nebulizer type aeroponics primarily focused on the facilitation of recirculation of the fertilizer solution; the reduction in energy consumption; and the production of conditions which are conducive to crop growing activities.Preliminary activities include: the determination of the duration of the roots of the lettuce seedlings (Lactuca sativa) to dry out under a dry sunny day and; the modification of a mechanical timer to meet the predetermined drying duration of the roots of the lettuce seedlings. Results showed that, while not on its soil environment, the roots needed to be aerosolized every after 24±2 minutes. Rather than the 15-minute fixed intervals, the modified mechanical timer assembly enabled the aeroponics system to automatically turn on for 10 minutes every 20 minutes. Fifty-one percent, or 49 plants, have thrived in the system in the first week, and was trimmed down to 19 plants, or 20%, the week thereafter. The electrical cost of operation of the designed system was computed to be 1.5785 Pesos/day. At the rated electrical charge of 5.3873 Pesos/kWh prevailing during the entire study, which took 275 hours, the total cost of operation was 18.0870 Pesos. The automated nebulizer type aeroponics, which came to be feasible, has many rooms for improvements. Advancements in this study have a very big potential for big advancements in soil, water,
