I'm trying to make things easier since I'm new and also since I'm building my own boxes and have read alot on going with all med. boxes for everything . I think it would be easier for me all around , so now do I go with 8 or 10 frame is there any down side to 8 frame med for all boxes . This may be all wrong but I thought I read that a 8 frame doesn't offer the insulation from cold of a 10 frame box in the winter , I don't want to do anything that would hurt them from surviving the winter .
