Thanks Navajoa,
I really couldn't find any info on growing them from seed so I just followed the same method I used for the cactus seed I got.
Take away container sealed with cling wrap and a media mix of sifted potting mix, gravel, sand and coco coir.
I bought 5 seeds and a week down, 5 have sprouted!
1 has toppled over on to its side but the other 4 seem to have dug their roots in, it's going to be a bit of a guessing game from here, but I will prob wait another few weeks and then prick a hole or two in the cling wrap, slowly acclimate them.
Fingers crossed I get it right.....
