I was wondering where exactly the best place to put this would be use the temp prob. I have it in the fridge right next to the carboy (as the photo shows). The temp prob is placed in one of the used Apple Juice jugs and had starsan in it. Is there any problems with me using it this way and what would be the better solution? Its only been in two days now, so I still had sometime to change it, I just need to make sure I am doing the most affective way.
