- Cost efficiency. HPS and MH grow light kits are some of the most popular kits out there because you get so much for so little! A ballast, 1-2 bulbs for flowering and vegging, a reflector, and other perks like light hangers and timers- all for a starting cost of around $150! Parts for HID kits, like bulbs or ballasts, can also be found at local indoor growing stores in a variety of makes and prices so you don't have to waste time and money shipping parts to and from international stores. Overall, HID lights are inexpensive and replacement parts are easy to find.
- There is a wide range of reflectors on the market, which means there are more options for various growing situations. LED's and T5 lights have very limited style reflectors for growing. HID’s, however, come in hoods, umbrellas, various styles of wings, and can cover plants beneath and in the peripherals of the reflector. Moreover, high powered HID’s typically weigh less than other high powered lights. For example, a 600w HID kit’s reflector typically weighs about 5-6 lbs. The heaviest part is the ballast, which can be wall-mounted to avoid stress on grow tent. Compare that to a 600w LED that would be at least 10-15lbs. HID’s offer a range of uses and are some of the lightest systems to work with, making them versatile and easy to fit any growing space.
- Because HID’s have a wide area of light coverage, HID's are optimal for commercial growers. The minimum coverage area of a 1000w HID is 6x6’, whereas most other high powered lights' coverage area is about 4.5x4.5’ during the vegging cycle and less during flowering. Commercial growers need a consistent amount of light in a given area and cannot afford to add and subtract lights during a garden’s life cycle because it can shock your plants if done incorrectly. The widest and strongest light coverage, for the most part, comes from MH and HPS grow light kits.
In the wake of all the new technology in grow light kits, it's easy to lose sight of traditional high-intensity discharge (HID) grow light kits and their benefits. HID kits (grow light kits that use MH and HPS bulbs) have gotten a bad reputation because of their heat discharge, yet HID's are used more often than any other style of grow light kit for several reasons.
