Water condensation tends to be extreme in the damp puget sound area. I hope to keep the hives drier this winter by using an empty deep box over the inner cover. This also makes it convenient to feed pollen substitute and syrup. I thought the deeps would reduce moisture in the hive, but Allready I have noticed that the lid is still very wet and dripping onto the inner cover. I dont really want to drill a bunch of holes in my deeps but that seems neccessary. I am thinking of drilling one 3/4" hole (just the size for a wine cork) close to the top of each side and stapling screen over the holes. Anyone tried this? Thanks for any comments. , Paul.
