Hmm take advice from a different somebody. If there is Bee space on each side of the telescope cover and an hole in the Inner cover you have a robbing portal.I always rest my telescoping cover on top of the inner cover so that it slants backwards.
Someone told me to do it during the Winter so any moisture collects and runs to the back of the hive before it drips.
Using an inner cover with the oval hole in the center, does the telescoping cover tilt really make any difference? I imagine that humidity collects most evenly on the inner cover, but maybe not. :::shrug:::
That is what I do. I have never met anyone else who does it so I thought I must have invented that idea! Now I know other people far more knowledgeable about beekeeping than I am think it is a good idea too."When the top is more insulated" than the sides of the hive, the coolest spot for the condensation to form is the sides, runs down and not on the cluster. so put a couple inch piece of Styrofoam under the top cover to "well" insulate it and it will not drip on the bees then either.
the picture provided,, would cause me concern,, over a driving rain/sleet from the "up end" of the outer cover, if said material is "absorbing of moisture" It could IMO be saturated after the rain and then drip on the bees, as it is level. If a tilted is "needed" I guess I would build one that has a slanted roof. I am in Northern Mich and I have never seen nor heard of "Lid Askew" I use a thicker Rim to accommodate the 2 inch foam.The need for a tilted (askew) telescoping cover relates to winterizing a hive for northern climates. The UofMinnesota teaches the placement of bildrite over the innercover, and the telescoping cover is tilted (place a stick on either end over the bildrite) so that the entire surface of the bildrite is exposed so that evaporation can occur from the four (4) sides of the bildrite, and the entire top surface. Bildrite is a fiberous construction material that will absorb moisture from inside the hive, and allow for evaporation to the outside to eliminate the potential for harm caused by buildup of ice or moisture.
JTGarass My comment specifically related to the picture in the first Post from Jackam yes the way you describe is another "way" Not sure how much "evaporation from 5 sides" happens at -5 F but I would think some comes out, as winter air is dry.Gray Goose - you overlook the existence of the askew telescoping cover protecting against rain. The fiberous material is completely protected by the telescoping cover, and the tiny distance between the top of the flat fiberous material and the bottom of the telescoping cover made askew (not flat, in a crooked condition) can be as little as ½ inch on one end (caused by a single spacing object like a stick) to zero inches on the other end of the telescoping cover. This resulting triangular space above the flat fiberous material allows for evaporation from five (5) surfaces - all protected from rain by the telescoping cover as to all six (6) surfaces. The fiberous material aides in the elimination of interior humidity. The hives’s outward appearance is identical to the appearance of your hive in Michigan except my hive has a telescoping cover that is ½ inch higher on one end - and it matters not which way it is tilted (right, left, back, or possibly front). Here is a link to the UofMinn brochure. https://www.beelab.umn.edu/sites/beelab.umn.edu/files/poster_163.pdf
The tiny separation does not increase the likelihood of wind catching the lid; I always use straps anyway. The brown bildrite can be seen, along with telescoping cover, now askew.
hmmm, I could not follow all that. I lost you at "warm, High pressure Air" And BTW I smoke Cigars. I would offer comment or feedback, but i'm not sure if the dumb Idea you mentioned is the tilted lid, or not using the tilted lid. well ok then, of to the tattoo parlerthis turns into a rant quickly but maybe the choose of words used to describe something resonates well with some of you and encourages an internal investigation. i understand the irony with this statement and attempting to offend most people, 3 crudely constructed sentences later.
it is a shame there are many adopted wintering methods which cause unnecessary stress to the colony. at the end of the day, these dumb ideas jeopardize the health of the colony, cost additional money, space and time to implement. but yet, it has become common knowledge because the football watching, cigarette smoking, tattoo displaying, mouth-breathers downvote science off the internet.
when one has an upper entrance it will exchange air quicker than a single, reduced lower entrance. there will be a minor vacuum which forms and the precious heat (warmer air holds more moisture) the bees produce is exchanged for cooler ambient air; warm, high pressure air will exit the top and draw in cooler, ambient air from down below(this is bad/undesirable and manifests in stress to the colony). we would normally want this nice warm bubble to be around the cluster but when the air is exchanged via these irrational wintering ideas adopted by many, this temperature gradient (bubble of warm air around cluster) becomes very thin and puts it in closer contact with cold air where it can fall out of solution in the form of condensation. the cluster has to work harder to maintain(consume more food to keep up with energy requirement...stress) an active temperature which permits movement to food. how are colonies dying with surplus food?
wintering is trivial...the goal is to trap and preserve the warm air as long as possible; reduce hive volume and entrance, insulate the top well and make sure hives bodies are sealed. as others have pointed out, the warm air will eventually make contact with a cooler, less insulated surface and fall out of solution away from the cluster; a non issue. yet people continue to buy unnecessary woodenware, waste money and time for a problem they create because they could not be bother to pause and think or establish a sound scientific foundation earlier in life. so now they feel uncomfortable and instead of trying to fix their scientific foundation, so moving forward their decisions can become more rational, they choose to exercise their freedom to downvote and the sheep soon follow.
peace and long life!
