HID, Metal Halide, HPS
High intensity discharge lights were the most common lighting solutions amoungst indoor cannabis growers for a long time, along with their metal halide and high pressure sodium variations. These grow lights can closely achieve the light output of the sun, but they use more power, generate a lot of heat, and the bulbs need to be changed at different grow stages.
