I have a digital, now my humidity is bumped up to 99%, holy crap. Must be an effective new 'trick'. I have a glass tank with a vented lid, so I soaked a bandana, put it on top of the tank then put the lid over it and proceeded to put another soaked bandana on top of it with a slit about and inch wide for ventilation and the heat lamp over. So yea, my humidity is now up to 99%.
