So i made a rack system probably a week ago and only have one tub in right now which is 41 quart my temperatures are fine hot side 90 cool side 78,substrate is paper towels(which i just changed so no moisture is on them),its heated with a uth (sticky kind),i have a 5 inch water bowl,And i have put a whole lot of holes in the tub 13 in front 11 on cool side 13 on hot side and 18 on back side and i have two hygrometers one reads 70 and one reads almost 80.My question is how do i get the humidity down because i'm suppose to get a new spiderball tomorrow and i don't know what to do.
