LED 101:Why LED Is The Best Grow Lights For Cannabis
Light Emitting Diode (”LED”) is a relatively, modern technology that is more versatile, efficient and also less costly than either incandescent, CFL, or HID bulbs. It works by way of an electrical current going through a microchip, which results in light. Also, with this technology, the heat produced by the LED lights are absorbed into a “Heat Sink,” which in turn results in less heat being released into your room.
What Are The Best Lights For Growing Weed?
They cost more. So, you could be asking yourself if the extra cost is worth it or not? And are LED lights the best lights for growing weed? That’s a good question, and to quickly answer your question: " If you are going to either commercially grow marijuana or if you are wanting to get the best yield for your cannabis crop. Yes, LED lights are the best lights for growing weed." I’m sure you’re wondering why. So, I will go over the advantages of LEDs over incandescent, HID, and CFL technology in growing cannabis and prove to you why LED is the best for growing cannabis.
Lumens Vs. Watts
LED bulbs are classified by their overall brightness. This measurement of brightness is called lumens. The more lumens you have, the brighter it will be.
Watts measure the amount of energy that is needed to power a light source. LED is not necessarily brighter than CFL or incandescent bulbs. But, CFL lights will use more energy to be just as bright as a LED bulb.
For your reference, I’ve included the following chart to the side and a table below, which can help you convert watts to lumens.
LED Grow Lights Vs. HID Grow Lights
HID bulbs (HPS and MH) are categorized by the type of gas the is used to make them bright. High-Pressure Sodium (”HPS”) and Metal Halide (”MH”), which produce different colors, are the two most common types of HID bulbs. HPS and MH each produce different colors of the visual light spectrum. So, for best results when growing cannabis you will need to change your lights from HPS to MH as you approach each marijuana plants growth cycles. Historically, HID and MH bulbs were significantly cheaper than LED bulbs. However, LED bulbs are now less expensive than ever; as a result, there is no real advantage to choosing HID bulbs instead of LED.
The only reasons to choose HPS or MH over LED is if you need to save money or If, you already have an HPS grow light system that works well for you, when growing marijuana, and you don't want to worry about learning new technology.
Personally, I agree that it could be a mistake to suddenly switch to LED as LED does have a slight learning curve. However, you should gradually test out LED lighting for your cannabis and then slowly make the transition into fully using LED technology.
