lamp will increase the production of cannabinoids and terpenes found in a cannabis plant’s essential oils. Like DE-HPS lamps, ceramic metal halides have a longer life span than the standard metal halide or high pressure sodium lamps. Ceramic metal halide bulbs have a rated life span of 20,000 hours, whereas many horticultural specifi c HPS lamps have a rated life span of 10,000 hours. High intensity discharge lighting systems have been at the forefront of indoor cannabis production since the beginning of indoor horticulture. Lamp manufacturers who specialize in horticultural specifi c lamps are continually upgrading their lamps to produce more PAR per watt of energy consumed. As long as the laws surrounding cannabis cultivation continue to regulate the number of plants a grower can possess, horticulturists will rely on lighting technologies capable of growing large marijuana plants indoors. Currently, HID lighting systems are the best choice for growing gigantic plants indoors. Of all the different technologies within the HID realm, cannabis growers are fl ocking to double-ended high pressure sodiums and ceramic metal halides. These two particular technologies maximize the amount of usable light energy compared with the electricity they consume. The high frequency ballasts combined with a bulb that electricity fl ows through makes double-ended HID lighting stand out among other artifi cial horticultural lighting sources. However, the longevity and incredible color rendition index of ceramic metal halide along with its ability to provide higher amounts of UV light for increased essential oil production have many cannabis growers fl ocking to that technology. Whether it be a double-ended high pressure sodium, a ceramic metal halide, or both, marijuana growers who utilize the latest in HID lighting technologies will be able to grow the largest plants in the most effi cient and effective manner
