Randy .. Rod is correct 100% ! Your basic flow-hive set up is an 8 frame regular old Langstroth hive. Nothing more n nothing less ! Living up North you'll have to add one additional 8 frame deep super. I doubt you will even us the actual Flow-Honey-Hảvest super with the fancy plastic frames.
I really don't understand these supposed bee experts. You could kill your colony in one of his 10 frame double deep setup just as easy.
I'd quickly let your fingers do the walking n try to quickly find a source for a Nuc or check with another member of your club. He sure isn't proving to be the best fish in the Sea !
Don't worry ! I've gotten crap about having a Flow also. But I really don't care because I know it's the same same as theirs ! At least I'm not prejudice n blind both. Just take your "nickels" n buy one from another vender !! Don't give up or get discouraged. We might not be quite as chilly out here in Puget Sound but got close n my Flow-colony made it gang-busters thru some chilly/snowy/wet stuff. Wet n cold can actually kill off Bees more quickly than dry cold !
So don't give up the ship n find yourself another better n more worthy mentor. That one sucks big time. Prove wrong just like this 72 year man is over here. My local dissenters now are wanting invited to my summer harvest with tougue in cheek .. I'm loving it !! I have an internal hive instrument package that proved n recorded how well my bees did all winter n I also took
Infra-red pix .. Trust me Flow-hive work !
Good luck n get with it ... Times a waisting bro.
P.S. I have a hive instrument package in my flow n showed me all winter how well my bees were doing .. Occasionally I also took these infrared pix. Bees did great all winter !
