Top Ventilation in Southern locations?
All of my hives have top ventilation/entrances the year 'round. I do this
by cutting a notch (1 inch by 5/16 inch) in each of my inner covers, and then
making sure the notch isn't blocked by the outer covers after I work the
hives.
The upper entrance has a variety of benifits, including provinding a vater
vapor exhaust port, and a usable emergency entrance during heavy snow
conditions.
