Exactly, I am in the same boat. How, why does it work and what can I use from it. When I started "77" we did not feed. I was unaware it was done, so in My history only in the last 10 or so years, Have I warmed up to the idea of feeding. My Apiary is more in line with St Cloud MN. I am 4 or so hours drive north of Munith. I am trying to overwinter NUCs this year. will see how that goes. I am not necessarily trying to maximize production per footprint. My goals are to try to overwinter my bees and have enough in the spring to split back to some target and what ever honey I get is fine with me. Luckly when the dandelions bloom the flow starts and ends with Goldenrod, so I have a fairly long flow. I have a day job and Kids, so I do not box swap in the spring, or have the time to manage too intensively. A few swarms go off each year and I am also fine with that as a means to a DCA in my area. Again for me who admittedly may be a bit set in my ways , Single box management is not for me. My Grandpa was a 3 deep guy in the 50s and most of what I do is what he did. I do like to read ,so I have been reading up on what I can find, it does not move me off my base much however. It does offer different options some of which I have tried. Hope I am not dating my self too much but the first time, Bears wiped me out I ordered 3 packages from Sears Catalogue "Starlight" was the name as I recall. Maybe 30-40 bucks each,, was was back at it behind an ele. fence.single 10f, 5f, 4x4, and plamers have shown good survival in your area http://www.rrbeekeepers.com/Meghan/Sustainable-Fall-Nucs.pdf
management and stock likely makes the difference.. I am going to go out on a limb and say there is a good reason people much more north of you keep in singles
obulisy there IS a reason why dubble/triple stack are the "standard", my guess is simplicity, bigger margin of error (safety net), and a stock that over winters in a large cluster
Single box management would seem to be an advanced skill for honey production. As I under stand it from friends keeping up in the mountains (8300' zone 4) they have a very short bloom season (last frost June 23, 1st frost sept 3) and with out single management they don't get a crop. The more compact nest alows for better spring build up (heat related) and to push the max in to the supers to be harvested, when the nest retracts they feed, this keeps fall flows(with there indejustabuls) out of the brood nest limiting the need for cleansing flights and improving overwintering.
absulty, I know people who plug up dubble deeps early spring feeding and then super and "magically" make huge crops. This is another argument used for single brood chambers
I don't care who does what, I just like to know the how/why something works or doesn't compare and contrast the advantages and disadvantages so I can make an informed choice
