That isn't true. Green light is the only part of the Visible spectrum that wont effect the flowering hormone.

I dont know as i've never read about UV light, but i highly doubt it would harm your plant. What i was talking about is that UV light helps flowering plants, but black lights dont have right right UV to Help them.
