> Is there a description of this method of hive increase?  I would be very interested in learning this technique. 

It's not so much a technique as understanding the timing. But there are at least two ways to accomplish this. One is to take brood and bees from your colonies over time to make as many splits as needed. Package bee producers know they can remove bees repeatedly and still end up with good colonies.

Another is called "nuking the bees" where the bees are simply divided up as far as they will go. A colony on one or two frames will literally hustle to try to get back up to critical mass, meaning more bees are actually raised by the smaller colonies than the large colonies would have done. 

Lots in the archives about these manipulations
