What's the point you're trying to make related to cannabis production? It's an interesting study but it's just about old metal halide lamps and the spectrum they put out. Did you grow those blueberry exclusively with the metal halide? I would love to stick a couple MH lamps in my grow room just to see what happens but I am at my limit in terms of heat and power usage. I'm at the point where if I turn everything up to 100% I start kicking breakers. All my lights are set on 80% right now. UV-B definitely has its uses, mostly as pertains to trichome production, but it's dangerous to use. It can cause skin cancer, damage your plants, and fuck up your eyes if you overdo it. UV-B only reaches earth about an hour or two a day when the sky is clear, and depends on where on earth you're located. Higher elevations and equatorial regions get the most UV-B. UV-A is much more common, and safer, so I'm only interested in using that to boost my plant production.It’s an old ass study … but just gives you an idea … the concept has been tested and trialed many years back
