IMO...Your temp is a little high during the day, which could cause the humidity to be so low but without knowing more about the environment around your grow space and what size space you have, it is hard to tell why such a difference from day and night. My temp during the day is 72-74degrees at all times and the humidity is between 35%-45%. At night my temp drops to a steady 60 degrees and the humidity is between 50%-60%. I have no issues with mold or pests and the plants grow great. Let me know a little more about the grow space please:thumbsup:
