I recently purchased a used home-made rack off of a breeder. The bins were holding perfect humidity for him, I guess the change of atmosphere in my apartment is more intense than I thought. Although the bins have holes, the humidity is ranging between 90-99%. I don't know what to do, but my boyfriend has some snakes in there on QT and we have no where else to put them. ATM I have the bins opened halfway, but I can't watch them all night. Is there a way for me to lessen the humidity? Can I make holes w/o using a soldering iron or glue gun (as I have none right now). Any help will be greatly appreciated!! Thanks
