The active ingredients of industrial hemp are mainly THC and CBD. These two ingredients are mainly concentrated in the petals of hemp. Therefore, the key to hemp planting is to make hemp flowers grow strong enough, and the light sources required for plant growth are mainly blue and red. Light and super red light, among which Hyper Red with a wavelength of 660nm is most helpful for promoting plant growth. Therefore, the cannabis planting community generally puts forward higher and higher requirements for super red light.

    As we all know, the highest standard red LED in the industry is Osram GH cssrm4.24, and its V8 performance is as high as 4.14umol/J@700mA. Most people think that this is already the ceiling of the LED red light industry. In fact, it is not. There is a very low-key LED in China. The high-end LED packaging company H-Gtreat Optoelectronics (www.h-great.com), as early as the end of 2020, has achieved red LEDs exceeding 4.2umol/J@700mA. (TYPE: HV4.24) performance exceeding OSRAM 4.24. And it has already been supplied in batches to some customers in Europe and North America.

    The comparison data is shown in the figure:

Product	PPE@500umol/j	PPE@700umol/J
Osram	4.2	4.0
H-Great	4.3	4.1

    
    H-Great has its own patented technology, which can achieve higher effects than the same industry under the premise of using the same chip. At the same time, it can also provide more competitive prices.
