I am considering buying some of the plastic supers shown under new products in the May Bee Culture magazine. Are there any disadvantages of plastic? I am aware that the old Walter T. Kelly plastic supers warped inward and the bees used propolis to attach the frame ends to the super walls. Any advice will be appreciated. Thanks.
