I start them straight in moist compost making sure there not buried to deep. Keeping them warm and moist is the main thing. I don't bother putting them under a light untill they have broke the surface of the soil. For germination and cuttings I find a heated propagator or heated mat really helps. Then its down to the viability of the seeds. On average it takes two or three days. Not always some can take 24 hrs where as others may take a week.
As mentioned root riot cubes are another excellent option. The biggest help overall though was getting a heated propagator. Especially for cuttings.
