As cultivators, horticulturalists, and master growers, we spend a lot of time thinking about delivering quality light to our plants. It's important to deliver high amounts of photosynthetically active radiation (PAR). But what about wavelengths outside of the PAR range - like UV light? Turns out that UV light can increase trichome density, THC content, as well as prevent insect herbivory and the spread of pathogens!

What Effect Does UV Light have on Plants? | Ursa Lighting UV light is radiation with wavelengths between 100 nm and 400 nm and it’s not visible to the human eye. UV radiation affects many aspects of plant growth, including the development of defense compounds and structures, prevention of insect and fungal attack, and DNA damage.

Do plants use green light, or does it just get reflected of a plant's leaves? We just put out a new article exploring the role of green light in plant growth and development. This article is part of a series covering all the colors of light, including UV, violet, blue, green, yellow, orange, red, and far-red light! http://ow.ly/woLW30iWMsf

Choosing the best lighting for growing cannabis can be intimidating, especially when there are so many factors to consider, like spectrum, lumens, PPFD, CRI, CCT, and more! This article is part of a series covering all the colors of light, including UV, violet, blue, green, yellow, orange, red, and far-red light! This focus of this article will be on blue light. http://ow.ly/Gr1L30iOsSo

Can You Increase Trichomes Using Light?
Trichomes are hair-like outgrowths found on the epidermis of many species of plants. Trichome number and size is, in part, regulated by light. This article will discuss the characteristics of light, such as intensity and spectral quality that correlate with trichome development. http://ursalighting.com/increase-trichomes-using-light/

In order to choose the best light for growing your plants, it’s essential to understand which wavelengths of light are required for normal plant growth. We will explore the range and function of anthocyanins and betalains and identify the wavelengths of light they absorb. Read More: http://ursalighting.com/wavelengths-anthocyanins-absorb/
