Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.

This research is the development of an energy - saving water planting kit. The objective is to develop a prototype of an energy - saving water planting kit by applying solar energy as an energy source that is controlled by the Arduino board through a blynk application and study the efficiency of the water culture planting kit. By comparing electricity usage rates between solar energy and electric power from the household. In this study there were 4 experimental sets. The experiment was water cultivation without installation 2 experimental sets and 2 experimental sets were installed using green salad vegetables. In research the 45 days growth period consisted of leaf length and width root length number of leaves and height. There is also a comparison of the efficiency of AB fertilizer and soy milk hormones to reduce chemical usage. The research has shown that the use of the soybean milk hormone provided a high growth rate of Lactuce sativaVar. Longifolla than AB fertilizer. There are many nutrients but only in small amounts. When used as a nutrient for plant growth needs to be changed daily. Considering the economic value using AB fertilizer as a nutrient will be worth more than soy milk hormones. For the installation of the instruction set and the LED lamp was suitable for Lactuce sativaVar. Longifolla growing than not installing the instruction set and the LED lamp. These can save electricity cost of 85 baht per month.
