| Abstract | This research aims to design a thermoelectric temperature control system for growing lettuce by aeroponic method and electricity consumption and the cost of the planting system was anayzed. The experiment used two types of lettuce as green oak and red oak. They were grown the comparison of aerophonic and hydroponic method with dynamic root floating technique (DRFT). The growth of them was measured from bush height, number of leaves, plant weight, bush width, and root length. The temperature adjustment of nutrient solution on the growth of them were analyzed variance by statistical method. The result showed that the water-cooling system can reduce the temperature inside the experimental set to about 7-11 ?C compared to the outside air temperature. The growth of green oak lettuces cultivated with water-cooling system was no statistically significant defference with hydroponic method with DRFT. The rate of growth of red oak lettuce cultivated with water-cooling system was low when compared with hydroponic method with DRFT. The electricity consumption of aerophonic water-cooling system was 0.106 kWh. |
