Had a thought while browsing my spring gardening catalogs...would it be adventageous or disaterous to utilize an electric seedling/root mat on the bottom board, say under a mite screen, to keep the little ladies slightly toasty throughout the winter? I figure it would be easy enough to regulate the temperature range. I use a similar set up with my spare fridge at home, when fermenting my homebrew requires a strict temperature range (yeast dictated). The system turns on the fridge when too warm, turn off when too cold, and if needed, can actually turn on a heating pad similar to above mentioned to control the temp. I'm thinking that if the bees are a few degrees warmer than usual in the winter, then it would be easier to 'uncluster' for food and perhaps get them a head start for the spring - earlier brood build up? Of course this would only be economical on a small scale, but could be useful for those of us that like to tinker. Let me know what you guys and gals think. PS - Sorry so long... :(
