I know this one has been beaten to death but I have a humidity question in regards to racks. I just got an RBI Iris sweater box rack and have been trying to prepare for the new pickup I will be making in 2 weeks. I have gotten the humidity down to 70% by drilling the tub full of holes. I have room for more if necessary but I was curious if 70% is ok or if I should bring it down another 10%. This is my first rack system and don't want to get my girl sick from too much humidity. Again, sorry for yet another humidity thread but I appreciate the input.
