Abstract - Presently there is a huge impact on traditional
agriculture due to climate change. Controlled growing system using artificial lighting can be used to increase the rate of production and capacity of yields. Recent development of light emitting diode (LED) technologies presents an enormous potential for improving plant growth. Photosynthetic organisms use natural light for photosynthesis, artificial light like LED can also serve this purpose. Electrical Load Estimation is critical in preliminary design level prior to any design. A reliable estimate is important to avoid any guess work. The work assesses lighting load estimation done by a scientific approach. The focus of the research paper is to solve the problems of engineers and farmers in estimating electrical lighting load requirement of a project especially a closed room or closed container.
Figure 1: Dutch Bucket System Crops can be grown using artificial light sources such as Light Emitting Diode (LED), High Intensity Discharge (HID) lamps. Plants perceive light in a different way than humans. For humans lumens (denoted by lm) is a measurement of total amount of light (which is visible to human eye) from lamp source. The lumen rating is directly proportional to the brightness of the lamp. The reason why lumens is not a good indicator for determining light requirements of plants, is that the light plants need most is almost out of the visible spectrum for humans.

1. INTRODUCTION Hydroponics is a soilless technique to grow the crops. It uses water mixed with nutrient solution which is allowed to circulate throughout the system. There are various types of hydroponics technique like Nutrient Film Technique (NFT), Media Bed, Dutch Bucket, Vertical Tower, Ebb and Flow, etc. Each technique has its own uniqueness, advantages and disadvantages and according to the type of crop, a suitable system is selected. For example, tomato plant can be grown using Dutch Bucket system. In Dutch Bucket system, several buckets are placed on the bench and each bucket contains individual plant. A reservoir is used which holds the nutrient solution. This solution is pumped using a pump through the irrigation lines and then dropped onto the plants using the emitters. Excess of solution is returned to the reservoir using return lines. A growth medium is used to support the plant. Generally, growth medium like perlite, vermiculite, coconut is used. Plants like cucumbers, peppers, potatoes, squash and tomatoes can be grown by this system.
