Top 10 Best LED Grow Lights for Growing Cannabis

marijuana grow LED lights, best hydroponic LED grow lights for sale

Now that growing cannabis is legal and/or regulated in many states, the market is growing for efficient and effective equipment for growing marijuana. LED Grow lights may be relatively new on the scene for growing cannabis, but they are quickly growing in popularity because they are so energy efficient, are easy to use and set up, and can be used for the full life cycle of your cannabis plants, from seed to flower.

Why Choose LED Grow Lights? LED’s produce much more light per watt than fluorescent or HID lighting. This also means that they run cooler, reducing electricity costs as well as the risk of fire in your grow room. Most LED grow lights come with small fans built in, and do not require additional ventilation except in special circumstances. Another bonus is that they do not require ballasts. Overall, LEDs return much higher yields for lower levels of electricity(and money!) consumed.

Any experienced marijuana grower knows what a pain it can be to set up a new grow room when you have HID lighting. HID lights and ballasts are heavy and require a lot of support to hang, and they reduce in brightness every year so they have to be replaced often. LED grow lights remain highly efficient for many years, reducing the need to spend time and money on replacements.

Choosing the Right LEDs: Usually LED lights are described in terms of the equivalent wattage you would need in a HID or HPS light to produce the same results. For example, when you see a LED grow light listed as “300W” it means that you can use it as a replacement for a 300W grow light, even though the actual wattage may be as little as 140W on the LED. Less heat means you save money in the long run on electricity to power the light as well as your ventilation systems.

When calculating the wattage required for your grow op, it is easiest to use the advertised wattage. The minimum amount you want per square foot is 30W, while the optimal range is between 50W and 80W. For example, if you have a 3’ x 3’ grow tent, you have nine square feet of grow space. Nine multiplied by 50 watts per square foot means you will need at least 450W of LED lighting. You can accomplish this either by purchasing a 450W or greater light, or by daisy chaining multiple smaller lights together.

This list contains our favorite LED grow lights for marijuana growers, with the specific needs of cannabis plants in mind. The list is organized by brand, so  you will need to use the calculations above to decide which wattage is right for your grow room. Make sure to follow all local laws in your area when shopping for and using the following pieces of hardware.
