Splits vs Grafting for increase?

When a beekeeper wants to increase from 20 to 200 hives from his own stock, is he better off using splits or grafting? It seems like grafting 50 queens at a time could get you to 200 a lot faster. Is there any advantage to doing it with splits instead?

I'm not going to do this myself - just a backyard hobbyist. I've just been reading some old threads about starting a bee business and am curious about why the graybeards often suggest increase by splitting.

If you start 20 grafted queens, you might end up with 10 mated & laying. If you make up 20 queenless splits and let the bees handle it, you might end up with 10 viable splits (with mated & laying queens).

Either way, much depends on your technique, timing & some luck. As you hone your technique, your success rates will likely climb.

The splits I made often do not produce a viable queen cell because we are in
a summer dearth right now. So grafting is the only option for me.
In the Spring time and early Autumn it is easier to make the splits as they will produce some cells for me.
I say to do a graft instead or better yet give them the newly mated queens so that the splits will be stronger to overwinter.

No.
Increasing by making splits and having the splits raise a queen on their own is very inefficient. That makes an average of 3 to 4 weeks of no brood being produced and at the same time the older bees are dying. It's self defeating as we are trying to increase hive numbers, so we don't want to be having so much down time with brood rearing.

Raising queen cells first, and making splits to place them in, reduces the amount of brood rearing down time by half or close to it. Grafting or some other way of producing queen cells ahead of time to place in each split is the way to go for increase.

Some advocate to make walk away splits as this gives full brood rearing break as a way of varroa mite control. But if you are wanting to do some serious increase, graft instead. Even better is to purchase laying queens to place in each split as you make them, but you stated you wanted increase from your own stock, so grafting is the way to go.

Personally, I see what I call "bee time" as the least plentiful resource where I live. So wasting what amounts about 25% of our bee time raising a queen that might mate and lay while also not having any new bees for another 15% of our bee time strikes me as the worst possible way to increase in numbers. Either graft and use ripe cells or outsource your queen production.

Walk away splits might work ok for going from a few to a dozen or so. But increasing 10 fold...? Depends how fast you want to get there.

I did not graft this year but still to make increase I had to produce queens. As afar as splits go. the bees themselves will be split then recombined a couple of times in the process. First a colony was made queenless by moving the queen to a nuc of her own and allowed to start to build it up again. the original colony then produces queen cells. Now I could have grafted larva. made plugs of selected cells or used a Nicot or Jenter type system to produce those selected eggs. It is a lot more work and cells get lost the way we did it. searching every frame to harvest the cells cutting them form the comb etc. Actual number form the first queenless colony was something like 20 cells produced and possibly 15 virgin queens produced from them. Those virgins are either in the original queenless colony or mating compartments at this time. Past results cause me to expect 7 or 8 mated queens when it is all said and done. Rounds two and three have the cells in the incubator now with none having emerged yet. In total there are 20 more cells and I am making no estimate of how many will actually emerge. Round 4 will be removed from the queenless colony today. I am expecting as many as 20 more cells from this colony. It is interesting to see how much of a difference just a few days will make in how many cells a colony will make. We started making colonies queenless on June 19th. even a 5 frame nuc of bees would make 10 queen cells. Now even a full size production colony will only produce a dozen or so. I believe in that same period of time our nectar flow has dropped off. I am ready to remove honey and start feeding them sugar water. Our goal is to make up as many nucs as we can and sell them next spring. We will continue to produce queens and attempt to get them mated until late July. We will not need them that long or nearly as many as we will produce. those extras will be offered for sale on craigs list. The limiting factor to how many splits we can make is the number of frames of bees we have. Our method may be inefficient but by far it is adequate. Producing far more queens than we will need. but until every split is queenright I will continue to produce queens. Waiting for queens to get mated is a big delay. We started June 19th and are still waiting for our first mated queen to be confirmed. Until then those bees are rearing their own virgin queen. If I where to do it again I would have combined those queenless bees with a mated queen until the time virgins had been mated and laying. Our timing was more of an issue of opportunity presenting itself rather than a plan. I would rather have started this process back in April but at that time this past spring we had no bees. We captured swarms and did a couple of cut outs. as soon as they built up enough to split we started splitting. Final measure for the interest of time to make a split and get it built up. I expect to have into November to build these colonies up to winter strength. we have mild winters so winter strength here would not necessarily be what it needs to be in other locations. I will be happy if they manage to reach strong 5 frame nuc size. So far we have gone from no hives to 10 with queens and 11 virgins in mating compartments. more more cells in the incubator and today as many as 20 more. From 0 to as many as 40 colonies in one season. 4 of them swarms and 2 cutouts. cutouts where tiny just getting started colonies. But we did have 6 mated and well laying queens.

What left you beeless in the spring? That is my big fear at this point, total wipe out.

I bought a box of Russians and have a reliable source of feral swarms that I've been catching since 2014. This has been my best season so far and I'm up to six colonies. If I can get four colonies through the winter, treatment free, it will be a big confidence boost.

Totally agree with keeping all the bees working. That is not a straightforward concept. There is a cost to setting up a starter, even a nuc starter. " Hive" is a vague term. Taking a frame from a double is not a major impact. Taking two from a single is.
Are you going to be ready with the hardware or is life going to have the equipment ready two weeks after you need it?
A cutdown split style keeps everybody working with a single frame making a lot of queens and as Daniel says the bees adjust to the future prospects. There are times that the young bees are better put to use in the original hive drawing new comb rather then making surplus queens. Just a higher long term reward.
There is not really a paper answer to your question, just absorb all the possibilities and adjust to your experience, local, bees and season. Not to mention the rest of your lifestyle.
