Grow Cannabis with LED Grow Lights


Grow Cannabis with LED Grow Lights


Cannabis grow lights are artificial lighting devices that are used to promote the growth of cannabis plants, serving as the sole source of light in indoor cannabis cultivation and as a supplemental lighting source in greenhouse cultivation.


With the legalization of medical and recreational cannabis in a number of countries, such as Canada, US, indoor commercial cannabis cultivation has developed into a much bigger industry that requires a lot of scientific and technological effort to successfully grow top quality cannabis. Among all those factors, the correct lighting source is one of the most important. Until recent years, HID(High-intensity discharge lamp) lights including MH(metal-halide lamp) and HPS(high pressure sodium) were the mainstream of lighting for growing cannabis indoors. But with the LED(light-emitting diode) technology evolving rapidly and the dramatic decrease of cost over the last decade, today, LED grow lights have become the new standard in indoor cannabis growing.


With more than 10 years of experience in horticultural lighting, VANQ provides plants-oriented and cultivation-proved cannabis LED grow lights for both commercial cultivators and individual hobby growers.

Why choose LED grow lights for your cannabis?

Growing cannabis indoors with artificial lights has a clear advantage in producing a higher and better yield. Because most top-quality cannabis cultivars that have the highest market values have been developed from generations of genetic optimization in indoor environments, and many of these delicately-breed cultivars are unsuitable for field cultivation.


HID grow lights have been used as the standard lighting solution for indoor cannabis growing for many years, and it is still being used in many commercial facilities. But over the past several years, we have also seen a clear trend that more and more professional and commercial cannabis cultivation facilities have shifted to high quality LED lighting, due to its proven performance on crop quality and consistency, as well as the significant cost savings in long term operation.

Higher Yields, Better Quality

Unlike HID lights like MH and HPS, the spectrum of the LED grow lights can be delicately tuned to generate the desired response of the plants during the whole growing cycle and to optimize the yields in both quantity and quality.


Over the past several years, VANQ has done light recipe research with worldwide professional cannabis growers on more than 15 LED spectra, against traditional lighting technologies such as HID lights as well as competitor products, in order to find the most efficient light recipe for indoor cannabis cultivation. Our broadband full spectrum spanning from violet to infrared with a fine-tuned ratio of each color within can speed the growth cycle and produce greater flower dry weight with more terpenes and a higher concentration of secondary metabolites such as THC, CBD.

More Light, Less Cost

A high performance LED grow light can generate the same or even higher light output than a traditional HID light with 50% less electricity consumption. Moreover, comparing to HID lights with a replacement cycle of 10,000-20,000 hours, LED grow lights can sufficiently work for more than 50,000 hours with less than 20% light loss.LED grow light is also much more stable and trouble-free, requiring less routine maintenance than other systems. The long term cost savings combining lower energy cost and less maintenance overheads allows cultivators to focus on plant improvements.


LED grow lights also generate much less heat than traditional HID commercial grow lights, therefore the climate control in cultivation facility can be much easier. Lower heat generation also allows cultivators to put LED lights in closer proximity to the plants without exposing those plants to excess radiative heat. In this way, cultivators can not only save on HVAC cost, but also use vertical farming methods to dramatically increase the space utility which is now a common practice in many commercial cannabis growing facilities.
