My weather conditions is similar to Hetty, so when I'm rooting my cuttings these days, they are outside in their natural elements. It is soo hot and dry during the day (and night) that the natural weather conditions keeps the potting soil moist. We usually have extreme heat during the day, so my cuttings are in part-shade, then it rains in the afternoon but still hot at night so I don't worry about the cuttings being wet and cold.
For me, the most important element when rooting is the "bottom heat", so my cuttings are on my brick patio or concrete walkway where it gets the maximum bottom heat. Lately, I've been rooting them in the coke plastic cups so I can see the status of the soil (moist or totally dry) and I can see when the roots start forming as well as the visible leaves. (Later when it is not so hot out I will take photos). If my cuttings look "slightly shriveled", then I would mist the stem in the morning. If they are "very shriveled", I would wrap the stem with paper towel and mist the paper towel everyday but not the soil.
Remember some cuttings do not root or show leaves in 6 to 8 weeks, so if you feel the soil is too dry, don't be afraid to give the soil a tiny sip (once in a while) but do it in the morning so it has a chance to dry out. I had 2 very shriveled White Shingapore cuttings that I had been trying to root since Feb and they still do not have visible roots and the claws are growing very slowly each day so I just ignore it...so long as the stem is firm (now looking plump) and not rotted. Ignore, ignore, ignore is my response...no tugging at all (baby roots easily come off) but giving them a little sip every now and then. Here in FL, Plummies can thrive on neglect once rooted.
