Abstract

A hydroponics planting technique commonly uses mineral nutrient solutions in soil- free water where it is an ideal way to grow vegetables, fruit, and soilless crops. Crops are places in the growing medium and the nutrient solution are supplied straight to the roots using the hydroponics method. The hydroponic planting system may help in producing a high yield of crops and good quality in a less space area to fulfil the needs of food supply. With respect to other types of hydroponic system such as deep-water culture, the systems normally used a huge amount of water where it may cause a heavy load to the structure. Hence, design of Vertical Nutrient Film Technique (NFT) helps in reducing the structure load such as the amount of water used inside the system and at the same time it will support to produce a better yield. The design of a Vertical NFT frame structure was based on5 tiers of growing media. The area of structure is 67 m2; 10 m length, 6.7 m height and 1 m width. Every tier of growing media has 250 crops; therefore, the structure can produce 1250 crops. The crops are planted with 20 cm x 20 cm planting spacing. The analysis of the frame is made using RISA 2D. The load imposed on the structure is calculated from the weight of the water, weight of the tray and weight of the plants. From the analysis, it shows that the middle vertical bar has a high force acting on it compared to both end support. The size of vertical frame use is 4 inches x 4 inches to support the loads in the structure. The size of pump needed to pump up the nutrient solution is 0.003 hp where the pump supplies the nutrient solution continuously throughout the system. The One-way ANOVA and mean comparison between groups for green lettuce and red lettuce under LED light shows a significance of (p>0.05) for both.
