Led grow light technology has been improving rapidly especially in the last 1-2 years. Although just about any LED grow light (even the worst ones) can grow good weed, some newer models developed specifically for medicinal plants are getting better yields, density, and plant growth rates than older and generic models. We are currently doing extensive testing between different LED grow lights to determine which are the “best”.
Are LEDs a Good Choice for Growing Medicinal plants?
LED grow lights are relatively new to the medicinal plants growing scene, but eco farm led lights 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.
Today’s LED models are much better for growing medicinal plants than the ones available even a few years ago. Many led grow lights samsung are full spectrum or “wideband” spectrum (instead of only 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. Other spectrum colors like red, far red, and infrared are important for the budding/flowering stage. 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.
There are 3 main types of LEDs that are most commonly used for growing medicinal plants. Each type of model has its pros and cons, so there isn’t yet a “best” LED type. Some are better for some situations than other.
1.Quantum Board 
The name “Quantum Board LED grow light” originated from Horticulture Lighting Group, though the best quantum boards is now sometimes used for any LED in this style. They tend to have relatively low wattage diodes which are spread out over a large area on a board. These are becoming more popular lately, and quantum boards canada seem to offer particularly good results for the amount of wattage used.
2.Spider LED
The “spider style” LEDs are similar to Quantum Boards in that the individual diodes are spread out and tend to be on the smaller side, but they are set on a panel with “arms” like a spider as opposed to a solid board. One very popular example is the SPYDRx line of LED lights. These typically have an extremely high price, but growers who use them swear they get better results than any other type of LED grow light.
3. COB Style
These grow lights use huge COB (Chip on Board) LED “bulbs”. Each COB is incredibly bright and intense because they contain multiple LED chips in a small area. COBs produce more intense light than other types of LEDs, and each COB uses a significant amount of electricity. Cree is most popular brand of COBs.
Instead of having dozens of small diodes, COB style LED grow lights typically only have a handful of huge COBs, each with strong lenses to direct the light down into the plant. These are rapidly gaining in popularity and are known for having deep penetration into the plant canopy.
