Are you using wax coated or plain uncoated plastic foundation? I have had the best results with wax coated plastic foundation in wooden frames. The bees draw it out just as fast as regular wax foundation. I tired uncoated one piece frames, and I found it took the bees longer to draw it out than normal. But I know of other beekeepers who have found no diference between coated and uncoated. Allen Banks Honey Road Apiaires http://www.honeyroad.com
