Dave,
My routine is to brush every cutting with Physan 20, and let them dry out. Then, I put them in barely damp sphagnum to root, and mostly they all do. Quality cuttings will root. By that, I mean freshly cut prior to sending.
When I see short, white, healthy roots, time to go into the cups. I use 20 oz cups, and the scissors or box cutter makes nice drainage and air holes in both top and bottom. JD punches them with an ice pick on the sides to aerate more. I put the rooted cuttings (try for the middle, but isn't it funny that a shoot will pop up next to the edge?) in the cup in a damp mix of 50/50 perlite and peat moss. I put the top on, seal it with masking tape with the variety and donor's name (mainly so I remember who gave me what). Then I soak the cup in warm water and let the water drain. Then I put a wrap of foil around the bottom cup leaving plenty of room for drainage.
The cuttings are in trays in a well lit room. No sunlight, but plenty gets diffused through the glass blocks in the bathroom where they reside. I don't remove the top unless I see signs of mold, and they get hit again with Physan 20 and allowed to dry out before re-capping. I soak the cups in a cup of warm water, let them drain when they are obviously light to pick up. Probably once a week for the heavy rooters, and less for the lagging rooters.
I love the surprises. One can be in the cup for a month, about to toss the thing to the curb, then, a little green nub on the cutting, or a shoot comes up from below.
After their leaves start pushing out the air holes in the top cup, I remove it, let them get used to air, then pot them into gallon containers.
That's my drill. Looking forward to hear others. Great thread, Dave!
