Growing weed indoors is possible, but not exactly the easiest thing to do, especially for beginners. The plant is deprived of natural sunlight, which can be a significant hindrance to its growth. That being said, UVB grow lights can provide a promising solution, but you have to use it right.
The UVB grow light has the capacity to mimic the natural sunlight to induce the growth of weed. Nonetheless, it can also put too much stress on the plant and can have it killed. With this, while it holds a lot of promise, you have to observe caution in its use.
If you are on the lookout for a UVB grow light that you can use for weeds, keep on reading the rest of this post and we’ll share with you some of the top brands and models available on the market, as well as the features that make them exceptional.

What is a UVB Grow Light?

A lot of you might have heard about LED grow lights, but UVB lights are seldom talked about. As shown in the products mentioned above, however, UVB lights are effective in improving the growth of weeds. More of this will be tackled later on.
To understand UVB, you have to know that there are three main types of wavelengths that reach plants, including weed:
- Ultraviolet A or UVA: It has a radiation of 320 to 400 nm. They make up 3% of the photons that can be found in sunlight. They also do not cause any damage to the DNA of the plant.
- Ultraviolet B or UVB: It has a radiation of 290 to 320 nm, which is more than enough to damage the plant’s DNA. With this, the UVB light is activated only in the late stages of growth.
- Ultraviolet C or UVC: This is the most extreme from the three and already has the ability to kill living cells, especially considering the fact that its radiation is 100 to 290 nm.
How UVB Affects Weeds
For many starters, this is probably the question that you have in mind. One of the most important things to point out is that UVB has different effects in different plants. Therefore, it is wrong to say that its effects on weeds will be similar to others.
Among others, one of the most important functions of UVB is that it improves the production of THC. The latter is a cannabinoid, which is believed to be a defense mechanism of the weed. When there is UVB grow light, it has greater UV exposure. The outcome is that it will defend itself against ultraviolet radiation, which is why it can produce a higher level of THC.
According to some weed growers, the use of UVB grow lights can help in increasing THC production by as much as 30%, although such claim is still a subject of debate these days. It allows the development of a protein molecule, which the weed develops as a way to defend itself from the damaging heat of the sun.
To investigate this claim, a research from Maryland has been conducted. The findings indicate that those that have been exposed to UVB radiation showed a higher level of THC, which is enough reason to believe that such supplementation is beneficial in growing marijuana.
Conclusion
This post discussed some of the best options that are worth considering if you are looking for the best UVB grow light for weed. The options are quite limited, but still, this does not mean that they are all the same. Take the time to evaluate the five products mentioned above and it will be easier for you to reach the right decision.

I think LED is good but it needs a huge initial investment for the commercial grower. So it will helpful if you publish a comparison table between LED & HPS light.
