Sceletium seeds have two basic requirements for germination. they have a
water soluble germination inhibitor which must be leached off either by it
sitting in a pot for several weeks or by mechanical means such as soaking in
running water. also the temperatures must be right or they will take much
longer to sprout or they wont sprout at all. temperatures above 78 degrees F
will tend to inhibit germination. we found that the best way is to have
temperatures which fluctuate daily between 55-60 and 75-80(which is when
they germinate in their native environment). we also tried 70 degree
constant warmth, but this was not as successful. we also tried a 1000ppm
gibberrelic acid treatment for 24 hours prior to sowing and this seemed to
cause all the seeds to sprout within a few day period(occuring after 8 days
or so) rather than having seeds continue to sprout over a month or so.
as you said, they can simply be placed in a pot and waited for. this is
basically what i am doing now in my greenhouse, which has the necessary
temperature fluctuation during this time of year. this can take up to 2
months for complete germination though, and is still dependent on
temperature factors. to recap, i think the average consumer should know that
a) they should use a sterile mix  b)soaking will improve germination  c)
high temperatures are no good for these seeds  d) temperature fluctuations
give better results  e) they should consider using a fungicide if they are
just going to put them in a pot and wait.
