In Virginia, as in most places not suitable for filming a remake of either "Ice Station Zebra" or "High Plains Drifter", our mantra is "ventilation, ventilation, ventilation". (Winter is over, so I hope I won't get too much flack from the tiny but vocal minority of beekeepers who chant the mantra "insulation, insulation, insulation" because they keep bees where extreme winter conditions exist.) Since you have a kit, maybe you can answer some questions: a) Is there any sort of "vent" at the base of the hive? If not, I'd be concerned about the airflow path for the lower part of the hive (brood chamber) below the entrance. b) Is the outer cover really placed directly on the top super? If so, I'd wonder if it would become glued in place by the bees, and unreachable with a hive tool due to the "lip" of the usual non-migratory outer cover. As an aside, I have tried the newer heavy-duty molded composite migratory covers offered by one of the larger migratory beekeepers, and they are a wonderful improvement over the usual wooden covers. These things are too sturdy and dense to be labeled "plastic". They appear to be made of something very dense and solid, like recycled tires combined with industrial epoxy. They even passed the "drive the Volvo over it several times" test. c) Is the entrance somehow expandable to full hive-width? If not, I'd wonder how the "fanning bees" could set up their usual formation to pull air into the hive for nectar evaporation. d) When it gets hot and muggy, will the bees cover the front face of the hive? I'd like to hear about this, if you care to post "results" later in the season. This (to me) was a big clue that the hive needed more airflow when I was first keeping bees, which I "solved" with old "retired" supers equipped with large vents covered with 8-mesh, and a bottom also covered with 8-mesh, placed below the inner cover. The bees rewarded me by covering the bottom mesh with propolis to block nearly all the spaces between the frames, proving that it was "too much of a good thing". In the same magazine, one can find an ad for the "Bee Cool" hive-top solar-powered hive vent kit. http://www.beecool.com The two products appear to be based upon very different basic assumptions about "what bees need". I'd love to set up a debate between the principles of each product at the next EAS, but I doubt that either would want to directly address the other's product as an "opposite" approach. Many have likely heard of the Imrie Shim, an "inner cover" with no solid panel, and entrance hole(s) added. (Go to http://www.beeequipment.com and search for "shim" to see a diagram.) These are intended as moveable top entrances to be added between supers to a standard langstroth-style hive during nectar flows. While a 3-way debate might be even better, one would have to be either very brave or suicidal to consider debating Mr. Imrie. There is also the "DE Hive" http://www.beeworks.com/D.E.Hive.htm which prompted me to seriously consider a 100% re-tooling of my bottom boards to turn the longer side of a langstroth hive to the "front", until I realized that I gained little by standing at the back of a hive versus continuing to stand at the side. This approach also stresses ventilation, but avoids electrical components. Since many of us reduce bottom entrances in winter, and add a top entrance, most often in the form of an inner cover with a notch or two in the "thick side", the kit appears to be very "winter oriented". The good news is that bees are very flexible creatures, and tend to adapt to and thrive in conditions that might appear to be "less than ideal" to one person or another. I'd be inclined to tear this hive down quickly when working it, just to see "where the bees hang out", if there is no inner cover, and "where they fan", if there is no usual "bottom board with large entrance" at the base of the hive. jim :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
