Re: considering going to foundationless
maybe try it out on just one or two hives, see how it works out for you.
if it gives you what you want, maybe start switching more of other hives over a few at a time.
in terms of cost benefit to effort expended, some of that depends on what you use and do already.
for someone who already has their own foundation press and a system that makes it efficient, they might find it's not worth it.
for others without all that in place and not having extra budgeted for retail foundation,plus shipping, it may even out or even lean toward foundationless a bit.
won't know until you have your specifics laid out in front of you.
there is no universal right or wrong here. experiment a little, tweak your own system here and there. you might find out it's worth going further.
No, I am NOT a bee "Keeper". Anything I post is just my opinion. Take it easy and think for yourself.
