I was actually in Seattle speaking with this team in regards to this topic specifically. The study is decent, but there were many variables not accounted for that increase exposure, that when I spoke with them, they acknowledged.
- This only accounted for UV from that specific light, not considering supplemental lights (UV Bars)
- It didn’t take into account enclosed spaces or reflection (your modern grow room is a tanning bed for plants and all that energy created by the lights has to go somewhere. The enclosed space and reflection significantly increase the chances your body absorbs that energy)
- Didn’t measure any other wavelength (Visible, IR)
- when I showed them our studies on the other wavelengths, they were stunned.
But it was awesome that they were actually concerned about this topic and the health and safety of growers.
