About a month ago I received cuttings from several sources. This was my 3rd set, and I planned it to be my last, for this 2015-16 winter propagation season. As with all sets, my goal is 100 % success but so far my last set (2nd) was only around 60%. Using school grades that might be a D minus at best. This time I used the baggie method, with NO heating mat, keeping the potting medium just damp enough to say it wasn’t dry and placed them in a plastic storage container in the relative dark basement furnace room where the temperature is a fairly constant 70 degrees. Two weeks in, I had two with roots hitting the sides of the baggie. Yesterday I potted them.
About a week ago I received another set of cuttings; so much for ending at 3 sets. Anyway, I spoke with BIGBADBILL and made another change in my propagation process. Instead of giving new cuttings a 4 to 20 hour soak, I decided to use his method of soaking until at least root bumps protrude. A week later 10 out of the 23 had significant root bumps. Those I placed in baggies.
All this got me thinking about the 3rd set. Out of 45 cuttings, only 4 shown roots to the sides that included the 2 I mentioned earlier. Now I was told that rooting would be slower, but after a month I just had to know whether I had roots, not or rot. So today I decided to de-baggie every cutting that had NO signs of rooting. Of the 41 that I removed from their baggies, 4 more had very small roots. Those 4 went into cups and the other 37 went into a wide mouthed plastic container of water with a very mild addition of liquid rooting hormone. They will be inspected daily as I change their water and will be placed back into their baggies once roots or significant root bumps are seen. I should mention that only 1 cutting appears to be rotted, all the rest still look great. I credit that to the very, very low amount of water in the potting medium and relatively lower temperature.
Was this the right thing to do? Should I be messing with the cuttings this much? Is there a better way? I believe after reading and doing what I have done so far, even though my experience with cuttings only started November 4th of last year, this is right for me. I normally soaked my cuttings from 4 to 20 hours but it seems as though leaving them soak until root bumps should give more guarantee that roots will actually develop and it should prevent any drying out. Changing water every day allows close, detailed inspection of every cutting, which will permit intervention if needed. This whole process is a learning experience. Many on this forum have shared some really great information but I do believe we all have to find our own method and what works for each of us. When I see something that does not appear to be going according to plan, I have to know why. If I make things worse, then so be it as long as I learn from it, although failing is NEVER the plan. Personally, I feel very good about these moves as I sense I will have a better chance to have more control over process now rather than leaving a lot to chance. I have included few pictures to go with this information to help clear up anything that may be fuzzy from my writing. I hope this is a worthwhile post.

Cuttings awaiting their turn to shed their baggie.
One of the cuttings with a very small root.
This cutting had the largest root. It was cupped to just above the dark bark.
2 potted and two cupped so far. The other cups hold Plumria cuttings.
The de-bagged cuttings in their soaking container. It sits on top of the insulated furnace cabinet. No, the water is not boiling, it's just slightly cloudy fom the rooting hormone. Temperature is around 75 to 80 degrees.
