Lately a lot of forum members have been showing concern about the wieght of their hives as they go into winter. Actually, keeping track of the weight of the hive throughout the year is a good means of knowing what's happening in your hive without opening it. Does anyone here have plan suggestions for good, durable, cheap scales that can be built and left under a hive throughout the year? Do you ever weigh your hives? How do you do it?
