Hi Keith,

I’m thinking that the Acrylic inner cover top may be contributing to your 
condensation problem, I have had the same condensation occurring with some 
homemade equipment that had smooth surfaces facing the inside of the 
hive.   It seems nucleation and growth of condensate nuclei on smooth 
surfaces such as the Acrylic inner cover, can occur more rapidly by both 
the direct addition of molecules from the vapor and from those adsorbed 
directly onto the surface.  I have seen some very interesting propolising 
patterns on inner covers of mine that had the smooth side facing in 
towards the nest.  The bees covered the entire top side of these types of 
inner covers with propolis, as if tarring a roof to stop a leak. 
 
From the pic, (if I am seeing it right),  you have the Acrylic inner cover 
is extended out to the edge, exposing it directly to the cool air.  This 
might chill the Acrylic inner cover causing more condensation to occur on 
the Acrylic near the cracks where cool are is penetrating.

Best Wishes,
Joe
