I have been advocating the above for many years. It would appear that
upwards ventilation is a European idea. Why it is frowned on in North
America, I for one fail to understand!
        I remember reading in one of the older bee keeping manuals (I
believe A.I. Roots) ventilation being discussed and at the time it
was considered necessary. How come it's fallen out of favour?
