I am regressing all my hives to small cell 4.9mm. I have been told that all "standard" foundation sold by the various suppliers is 5.4mm cell size.
To get the bees down to 4.9mm a step of 5.1mm is required before they will readily go down to the 4.9mm foundation.
In searching for a source to purchase some 5.1mm foundation I called MannLake about it. I was told that ALL their foundation is 5.1mm unless stated differently,
I can't find that claim anywhere in their catalog or on their web site. Has anyone measured their standard cell size foundation to determine its actual size? If their claim is true, they are missing a BIG selling point for it, IMHO.
