Triple mating nuc
Still making more of hivemakers mating nucs for next year. To save time, materials and roofs! Made a triple, side by side. Two entrances on one side and one on other. One roof does them. Then made another so can be stackable (ie 6) under one roof. Time will tell over drifting etc, but maybe custom paint job will minimise this.
Also solved the feeder problem. When in USA, visited bee farm that used double poly mating nucs with internal feeders. Guys used folded metal mesh in feeders to stop bees drowning. Got some over there in hardware store, back in suitcase, $6 for enough to do 200 feeders - result
Also, found a good alternative to 2mm perspex for inner covers ... 400 micron binding covers, brings unit cost down from £1.35 to 26p and easier to cut to size
