I will be transitioning to 8 Frame Mediums for Brood from 10 Frame Deeps next year here on the East Coast ( NJ ). I am researching as to how many Mediums I will need for this setup and I am looking towards those Beekeepers who have done the same in the last year or longer, I keep hearing that 3 Mediums are adequate for 10 Frame setups, but working with 8 Frame equipment has me wondering. What does the Hive Mind say :?
