Re: Sealing hive with Silicone?
The issue with sealing the hive is that bees are living creatures (hopefully), and humid air is simply a fact of life where creatures live. Your hive is likely to be more humid than the outside air. In cold weather if that humid air is not exhausted to the outside, there will be condensation inside the hive.
So if you are referring to sealing the outside of the wood endgrain, fine. If you are trying to seal up every possible crack from air movement, then that isn't going to help keep the inside dry.
