well there isn't much moisture in the tank, the hygrometer in the tank is in the yellow around the 36% mark which is the average of what I've been keeping them at, and the plants honestly don't need much water or moisture or humidity... I've even read that pathos can grow as an "air plant" so only with sunlight and a light mist every now and then. and the other plant i have is a low moisture plant as well (hence why i chose them...)
