With ever-impressive technological advancements surrounding us at all times, the lighting systems used for growing medicinal cannabis continue to increase in complexity, and in effectiveness. HID (high intensity discharge) grown lamps like MH (metal halide) and HPS (high pressure sodium) continue to be the top choice of professional cannabis cultivators. However, new LED (light emitting diode) lighting systems are causing quite a controversy in the marijuana cultivation realm. While most professional growers continue to go with the tried-and-proven, yet expensive to operate HID lighting systems, many new cannabis gardeners are going LED.
One thing is certain: if LED lights do prove to be able to produce the same large, optimal-quality buds as one can grow with HID lighting, then it's pretty much a no-brainer to go with them. Scientists know that cannabis plants cannot absorb many of the color bands emitted from HID lighting lamps. That means that those light rays are just bouncing around causing heat. If and when definitive proof is presented showing that LED lights are just as effective as HID lights for cultivating premium marijuana, the end of the HID lighting market will be near.
So for all of you that are growing your own medical cannabis at home out there, consider your lighting choices carefully. Both HID and LED lighting components have their pros and cons.
