A concept of small size greenhouse using unseaworthy used containers for hydroponic lettuce was suggested by Greenology. Forty-footer used-container being retrofitted that accommodating two rows of multi-tier continuous-flow nutrient solution channels fitted with 25W full spectrum LED grow lights (model G663100-240W25RB) are positioned approximately 500mm on top of the vegetable. Nutrient film technique (NTF) is deployed to ensure the roots of plants are exposed to adequate supplies of water, oxygen, and nutrients. A shallow stream of nutrient solution is recirculating past the bare roots of the lettuces. The ambient temperature of the small greenhouse chamber is controlled between 20° to 24°C with humidity of 40~50%. The growing cycle of organic vegetables are relative shorter than that of the conventional farming. Commercial greenhouse
There are two basic types of LED grow light respectively designed to promoting visible light spectrum for photosynthesis throughout the vegetative and reproductive growth stages of the plants. Full spectrum ranging from 400nm to 700nm would be used for vegetative stages whereas pure white spectrum between 6000 to 7000 kelvin are provided for reproductive growth stage of plants. Lighting fixtures are designed for growth of plants in the greenhouse of various height.
