Second sunny day in a row, neither of which were predicted by the 10 day weather forecast....
Still the plants look happier.

I was not expecting flowering just yet. I was planning to repot and top dress with shells this year and perhaps
add limestone chips to the compost to see if I could boost the growth a bit. I think I'll hold off on this now.

Thanks for the comments and also for the info on camera lenses from el48tel...

Epithelantha micromeris L737. This plant was from seed sown two and a half years ago- seed was from ADBLPS. The spines change as the plant matures. I think this plant still shows mostly immature spines - except for the longer ones at the top of the plant. The flower is 4mm across- the plant 2.5cm ac...

Nice!
But don't you trigger flowering in these plants with colder nights?
Should be no problem this year...

It looks like a neaty arranged plate of samosa to me!

I don't think coir can really be used as a straight swap for peat.
I've used ericaceous peat-free compost for peat- they're typically a mix of coir and bark products.

I still use a JI based compost with about 1/3 drainage. I'm not growing plants in a greenhouse so flooding pots when watering is something I need to avoid. So I'm not too keen on mineral composts. Getting a good JI substitute that is peat free is still a challenge though. Biggest step forward for me...

Even the pigeons don't seem happy with today's weather...

There is Hypertufa -made out of cement, sand and peat. Of course you'd might have to swap the peat for something similar.
I remember making containers out of this years ago- over time the cement component settles down and does not leach too much.
