Thanks to all for the good information... I'm pondering whether to bother with the light meter or not, other than out of pure curiosity. I should probably just be happy that I am blooming what I'm blooming indoors.

One other thing, for indoor growers, I'd mention. Dust and water spots can dramatically reduce light intensity on glass. My neighbors must think I'm psychotic, but I clean my windows inside and outside fairly often so that this doesn't reduce the incoming intensity. Even the type of glass thickness, single or double pane, etc. affects what makes it indoors. I read somewhere outdoor intensity can be cut in half just coming through glass.

At any rate, I'm sure this thread will prove useful for others in the future.
