One of the largest Wholesale ornamental growers, Iwasaki Bros. Inc. has installed LED top lighting at three growing areas this year. Philips LED top lighting was installed which rendered a decrease in their energy costs as well as money saving improvements in crop growth. Improvements such as faster rooting by 5-7 days, faster growth of roots than the tops, reduced pre-transplant and post-transplant loss were seen.
Installation of an outdoor Par Sensor in one of the tricks which can help you determine what time of the year and how long you need to run the LED lights. The Par sensor helps determine how much light is being lost through shade, hanging baskets and greenhouse glazing. Operational flexibility can be made easy by the use of switches. Row of five to ten lights can be controlled at one time by turning off portions of the greenhouse while the crop expands and contracts. The customization of light required by crop can be done by having a number of lights on individual switches.
