I thought that I would pass this on:
I have center supered a double, full depth or double deeps, with 100% Pierco bees wax sprayed 6 & 1/4" frames off and on over the past years with good results.
The reason that I center supered the doubles is that's where heat and wax producing bees accumulate.
I have also top supered strong singles with 100% Pierco frames with good results.
Comments are welcomed,
