| The Growers Guide to Cannabis |
| LED grow lights have exploded in the last few years with more advanced versions seeming to appear monthly. But amongst marijuana growers there is heated debate on the subject, with traditionalists yet to be converted to the new technology |
For patients who need medical marijuana, the progress of LED grow lights has been closely watched. The lights, which promise greater energy efficiency and lower heat than their high pressure sodium and metal halide cousins, have gained increasing visibility in the cannabis community.
LEDs (short for light emitting diodes) were first invented in 1927. More efficient than nearly any other type of artificial light, these diodes were too weak to be a contender for growing plants until recently.
But continuing research has resulted in LED lights that are more powerful than ever before. Within the last few years, many LED grow light systems have sprung up on the market for indoor gardeners.
Some claim the LED grow light technology may finally put the cultivation of a few marijuana plants within reach of anybody who has a few extra bucks and a spare closet.
