So, how does everyone attach their hygrometers and humidification devices? Some humidors come with a metal plate in the lid and you can use magnets to attach them, some do not. Right now, in my older humidor I just have the hygrometer and humdifier just laying across the top of the dividers. I'm wanting to attach them to the lid and clean it up a bit. I was considering velcro or magnets with adhesive backing but got to thinking, is it possible that the adhesive used to attach the velcro or magnets to the box and the devices could alter the flavor? Is there really any other option other than velcro, or magnets with adhesive backing? Thank you for any advice.
