Tecophilaea from seed, was Supersoil

I grow Tecophilaea cyanocrocus most years from seeds harvested from 
my mature plants. I use my normal seed mix, which is equal parts 
sharp sand, screened peat, and ground pumice. I used to put granite 
grit on top but when I ran out of it a couple of years ago, I tried 
pumice and found it works just as well, though it can develop algae 
after a year or two. I don't sterilize the seed soil because I feel 
that as soon as it gets into the natural environment (i.e., as soon 
as it's watered and placed on my deck or in the solarium), it is no 
longer sterile anyway. I don't reuse the soil for other seeds, 
though, I mix it fresh each fall.

I would note about Tecophilaea that it germinates in winter, but the 
seedlings tend to stretch out when kept under glass, as they have to 
be here. Nonetheless, almost all produce bulbs that can be identified 
and potted on the first year, after which I put them in the bulb 
frame, where the higher light level and, perhaps, the colder winter, 
keep them compact and in a normal growing cycle. I've raised hundreds 
of them this way. I don't hand-pollinate the flowers, but there are 
so many different pollinators here in spring that almost every flower 
sets seed.
