Changes as the day goes. When the lights first come on, they smell a bit sharper…more citrus and pine. After the lights are on a while, they smell softer and sweeter. Well, actually I am describing #4. It kind of took over and is covering about 2/3 of the 6 ft^2
IME if you wet one of these things they can smell pretty raw. I wonder if perhaps some of those skunk smells everyone remembers from when the windows were down were after a rain…then again maybe it really was a skunk.
