Thanks for the input guys, I appreciate the feedback.
Well we are having a warm, very wet fall here this year. I just made up my quilt boxes and put in the shim. I will winter the same configuration as last year. IMO it works great. In fact I would recommend it to any beekeeper reading this that winters in a cold climate.
The set up is three deeps. (top one is honey) with a innercover with a 3" screened feed hole to vent moisture up into the grass filled quilt box above, A three inch shim, then the quilt box, a lid with a 1" foam board in it.
Also a small top entrance.
Its important to open it up after the fall rains and honey drying, to swap out the inner cover, and lid to a dry one. The lid will be soaked this time of year from moisture, and the inner cover can be moldy and damp. We get a lot of fall rain here.
Its a good idea during the winter to open the quilt box and dry out the grass once in awhile on any sunny days, or swap out the grass. And dry the lid.The moisture goes up through the 3'' feed hole in the inner cover, into the quilt box and condenses on the lid. The grass stays dry, pretty much. Just a little dripping on top, it it cant get past the inner cover so the hive stays nice and dry.
I have a bunch of sugar bricks from last year so will use them up, I wont use a single brick, but a jumbled pile of broken pieces Works better IMO. and will soak up some moisture as well.
I will wrap again , and mouse guards of course.
last year after my hive starved out, when cleaning the dead out just a few days after it died, I noticed the inside walls were smooth shiny ice. not frosted like it should of been, so I assume they were using it for a water source, so must be important to have some moisture in the hive. In the right places of course.
I also watched on a warm spell, water literally running out of the entrance from the walls thawing out.( I don't turn my entrance reducers up like some suggest.) And wont after seeing that.
I am in much better shape than last year. I finally figured out open feeding and that helped put on the weight fast. I have been trying to jar feed them up to weight in the past, they just wont take enough like that.
