what types of hives work best in Nova Scotia ?
I think the vast majority of people run Langstroths, but I think that is true anywhere. The only person I have heard of (not that I know very many people) any different is Adam Foster Collins, who runs a couple top bars that have been successful the past few years.
Joanne had sent out an e-mail earlier this year saying that top bars aren't really viable in Canada, but it looked like it was completely based on theory instead of practice. Adam runs top bars are they are making out just fine.
