This may be a silly question but do cartos dry out and gum up faster if left open on batteries during the heat of the summer? I started vaping in January and our house is humidified during the winter so I always left the carto uncovered without second thought, but with warm weather approaching I'm wondering if I should at least cover the end with the rubber cup to prevent evaporation. I'm more worried about thicker liquids gumming up the carto than anything as I don't use that much liquid to worry about liquid loss. Thanks.
