I only have experience (very little at that!) with regressed bees. I put them straigt to foundationless frames this year with fine results. The brood combs were in decent shape. Honeycomb needed some work. If they make it through the winter I'm back to not having any spare comb. Anyway I have two treatment free nucs coming next year they are on homemade foundation. I would like to regress them and then go foundationless.
I'm reading about HSC and the PF series. Anyone have any thoughts about using one over the other? I read something interesting about using a follower board to control how much they draw on plastic so you can drop foundationless in sooner. Thoughts?
