Seeking advice on sowing

[supergodzilla]

After purchasing the excellent book ‘Secrets of Namaqualand Succulents,’ I’ve cambered down the rabbit hole of buying winter growing South African geophytic bulb seeds. Autumn is fast approaching but there is very little info online about growing these genera from seed.

Does anyone have any experience with growing from seed:
Albuca (bruce-bayeri, concordianum, namaquensis)
Bulbine (bruynsii, mesembyanthememoides, tortilis)
Dipcadi (crispum)
Eriospermum (titanopsoides, assorted others)
Ornithogalum (unifoliatum)
Trachyandra (falcata)

Would love to hear your methods if so.
