The other night my SO noticed the grow lights were still on in the spare room after he went to bed. This is something I'd never noticed, being a Benjamin Franklin-style early-to-bed human. He, on the other hand, stays up and does whatever it is people do who stay up late in the living rooms of suburban houses. Watch things, presumably. Exist in the dark. Anywho. Nobody knocked over the grow light. Allegedly. This is a mystery in three parts.
