Introduction: Are LEDs a Good Choice for Growing Cannabis?
LED grow lights are relatively new to the cannabis growing scene, but they have become wildly popular over the last few years with their ability to produce great yields while staying cool and using a reasonable amount of electricity.

Yields! With a quality LED grow light and an average-to-good grow, you can expect yields of about 0.5 to 1g/watt. The final yield depends a lot on strain and grow skill, but that’s a good rule of thumb for most models. For example, a 200W LED (200W true power draw, not an “equivalent” wattage) would yield about 100-200 grams on average, or 3.5 to 7 ounces.

Today’s LED models are much better for growing cannabis than the ones available even a few years ago. Many modern lamps are full spectrum (instead of purely red and blue light diodes, which product a bluish purple light and are sometimes called “blurples”). Full spectrum light is easier on the eyes and adding at least some amount of green light to blurples typically results in healthier growth. LED manufacturers have developed specialized lenses to point light directly to the plants and increase penetration, resulting in bigger yields for the same amount of light compared to older models. There are also many different form factors, with everything from the casing to the size of the diodes varying from model to model.
