How much UVA is appropriate?

[Mr.Estrain]

I was looking into building a PLC light. When they're in stock of course. I wanted to add some UVA supplemental strips into the build. I was thinking the 7 gaps in the PLC build could be utilized for supplemental lighting, I was thinking 4 UVA rapid led strips, one in every other gap, giving a nice spread. Is that too much, just enough or not enough. I was thinking a xlg 200 would be suitable to power them.

I'm a noob with regards to LED but am comfortable with electrical.

I think that's the right driver for what I need but if not feel free to educate me.

What's your thoughts on supplemental lighting?

I would use a uv light for the last 2 hours of the light cycle to induce plant sleep.
