Here are my Long hives with 22 frames each, I use the bottom disc for ventilation and the 3" entrances built into standard size Lang lids for the bees to come and go as they please. We opened one a week ago when the temps hit 35 degrees F and there were 11 frames full of bees with the rest full of honey. Next ones I build will hold 30+ frames.
