Another interesting aspect of plastic foundation is cell size varies
between manufacturers. In the trial I ran I did not measure it but did
so after I decided to shift back to foundation.

It varied from 5.4 to about 5.0.

With all the discussion on cell size and if smaller cell size promotes
healthier colonies, comparing different manufacturers may not be taking
all the variables into account.
