In 1988 I purchased 125 col. with 25% plastic frames in the brood
nest. Since then I have switched entirly to these frames. We now have
quite a few brood boxes with only plastic and have had no problems
with wintering because of them. I suggest tring 10 frames to the box even
if you don't like that with wooden frames, the perfect spacing allows
easy manipulation even with 10 frames.
