>A thing that I don't like about foundationless is that it needs much more care. I have over 30 nucs and it's OK for me but I couldn't imagine a commercial doing this.
I have about 200 hives and half of my frames are foundationless... it's much less "care" when you have some drawn combs that are straight. A straight drawn comb in the middle makes a lot of difference. A lot of drawn comb makes even more difference. I can't imagine doing 200 hives and wiring wax foundation for all of it. THAT would be too much work.
