I'll give it a try to see if it's the case, thanks.

That was my first thought too but it doesn't wipe or wash off

Hopefully the zoomed in picture will help.
They are being kept under led lights with my lithops.

I have noticed over the past couple of days that my pleiospilos nelli have developed small white patches. They are not powdery and do not wipe or wash away. Could this be bleaching from too much light or not enough?
Any help much appreciated thanks.

A lovely collection there. Some handy information too.

Very nice. How long did it take to go from seed to flower?

Wow, very impressive!

I've placed an order with them, fingers crossed the seeds will be viable.
I might start a new diary thread when they come for future reference.

That's reassuring, thanks Mat.

Can anyone recommend a good supplier of adenium seeds please. I'm not sure I trust the China suppliers going by reviews. Thanks
