Outside Lighting a Problem?

I have a location for a single plant outside grow which will be near, but not directly beneath some outside lighting. In other words, a distant outdoor flood light might occasionally throw some faint light on the area where the plant will be. Will this be a problem? Again, it won't be a direct "beam" of light on the whole area, but obviously enough to have me wondering. I know indoor light leak can be an issue, but maybe the contrast outdoors with sunlight being so much stronger will make this less of an issue? Thanks.

ive got a streetlight directly outside my garden and it makes no difference to mine

Thanks! I figured as much, but again, for indoor growing, there is SO much emphasis on dark being as dark as possible. Thanks again.

its gonna be an issue when the plants are flowering.
you want it to be completely dark when its flowering

Yes its a major issue. When it s time to flower, your plants wont. Should have thought ahead, anyway try to get rid of it.
