Top 5 Best LED Grow Lights for Growing Cannabis
Now that growing cannabis is legal and/or regulated in many states, the market is growing for efficient and effective equipment for growing marijuana. Follow all local laws in your area when shopping for and using the following pieces of hardware.
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.
LED’s produce much more light per watt than fluorescent or HID lighting. This also means that they run cooler, reducing the need for fans and the risk of fire in your grow room. Most LED grow lights come with small fans built in, and do not require additional cooling except in special circumstances. Another bonus is that they do not require ballasts. Overall, they return much higher yields for lower levels of electricity consumed.
Any experience 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 lights remain efficient for many years, reducing the need to spend time and money on replacements.
We have put together this list of the best LED grow lights for marijuana growers, with the specific needs of cannabis plants in mind.
