Hello,
I was wondering what everyone does with their Flow Hive 2 Tray for winter? I read that people turn it upside down, I am assuming we can turn the vent in the back down for less air flow? But how to deal with the Tray as it gets water in it sometimes and i dont want the water to freeze.
I am located in NJ.
Hello and welcome to the Flow forum! 
Yes, I would do both of those things - turn the tray upside down and turn the vent in the hive stand. If it is upside down, frozen water should not be an issue
