i have a dry room set up with 2 oscillating fans and an AC unit to keep my temp at 60 degrees and a dehumidifier that is set to 60% humidity I have all my plants hanging now in the room . I have a hygrometer as well but the hygrometer reads 50% humidity and the dehumidifier reads 57% humidity ... which one is correct and how to determine this ? Any onsite on this would greatly be appreciated . Also I was wondering if the humidity is low can you put a humidifier in there to bring it back up to 60% ?? My thinking is no because of risk of mold .... ?
