I was reading an older post about some one who had a snake with an RI, and one of the things suggested was to keep up the humidity. When that was suggested, they were told to make sure not to spray the substrate, and focus on the plant/plants. My snake doesn't have an RI, but I spray his cage to keep the humidity around 50%(ish). When I spray I moslty focus on his plastic plant and a little on his wood branch(because it's mostly under the light and I figure it will evaporate rather quickly), but I also lightly mist across the substrate. Not enough to soak it, just a light mist over the top from far above. Like, just one "spritz". His substrate is aspen. Should I stop doing this, and just focus on the plant and/or branch? The substrate seems to dry pretty quick...
