grow light for greenhouse farming 

Greenhouse is a structural building where plans are grown that grow lights would be essentially required for emitting an electromagnetic spectrum appropriate for photosynthesis. It could be used for soil or hydroponic farming of vegetables, fruits and flowers. The size of greenhouse could be ranging from a small shed or a large structural building enclosed by horticultural grade glass panel or polyethylene film. It should be featuring with greater control over the growing environment of crops such as temperature, artificial lights, atmospheric humidity, irrigation and fertilizer application, etc.

Small size greenhouse

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

Commercial greenhouses are commonly used for growing vegetables, fruits and flowers. It is being recognized as an important resource of food supply free from limitation of meteorological conditions. It allows greater control over the growing environment of plants, thus enable to supply vegetable, fruits and flowers for all seasons.

Commercial greenhouse farming could be of either soil base or hydroponic or aerophonic that technically requires effective control of the room ambient temperature, illumination of natural lights or artificial lights, irrigation system, nutrient solution or fertilizer application and atmospheric humidity.

The common size of structural greenhouse used to be 100 meters long with the width ranging from 8 to 12 meters that the height would be determined by the type of plants. However, LED grow light could be positioned at the level of horizontal beam of the structural framework.



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.
