i sowed out one of the two sources, and got so far ~20% germination! proly get germination with source 2 aswell, let's hope so.
i assume, the temperature in my previous attempt was too high.
this time aswell, i sowed them out into small individual pots, and not into small punnets.
i guess the small individual pots contain more potting mix, per seed and don't dry out as fast after watering, as the punett.
what, i mean is, that those seeds obviously don't want to be stressed out too much.
the seeds were sown outdoors, but under a verandah, no bottom heat, no dome.
the polarisation of the seed is, plant with the sharp end downwards, ~5mm deep.
i sieved the toplayer of potting mix.
one emerging seedling had still the endocarp wrapped on it's head, so i just, hilled up some potting mix around this just emerging seedling, and 24h later the endocarp had fallen off, by itselfe. so no surgery needed!
i searched the web a lot, around hoodia, and one mature specimen can weight up to 30kg, so the professionals say.
