I am getting sporadic mildew on random nugs. I can't tell if its too cold or too humid. My grow book says that anything under 76F will trigger mildew Someone at the grow shop told me because I run my lights at night, the early morning dew/humidity is hurting me. I have a 6 inch blower, blowing strait from outside to the low end of the room. He then recommended a filter or pantyhose to stop the water. I know that filters and pantyhose don't filter humidity, but the label on the on of the filter says its stops mold and mildew.

Will a filter help with this mildew?
Should I raise the temps 5 deg F?
Also the last 3-4 days humidity in my area has climbed on average 15%, could that be the cause?
