Re: Searching for Nuc entrance disks
I have no complaints about Mann Lake steel discs.

Dealing with propolis is just one chore beekeepers must deal with. I read somewhere vaseline discourages propolizing. Was that on Flow hives?
All of my opinions and suggestions are based on my five decades of actual beekeeping,
not so much on book learning, watching YouTube videos nor reading internet sites.
