Nice chart, thank you!View attachment 3595889
half amount of UVB for indoor lighting as we have no Infrared in our lights
BTW some UVA (3 - 5%) at 365nm will have the same effect and it´s safer for your eyes and body
Not saying it's true, but I've read papers suggesting that UVA is relatively unhelpful and that the plants clearly responded best to UVB.
One big reason I'm interested in these UVB LED lights is how specific their spectrum output is. Thus it would not take many watts at all to achieve a good dose of exactly the right spectrum.
