Hi Marion,
I got my Arachnis [top stem cuttings] from Queenslnd back in Spring last year [my second attempt at growing them- read keeping alive
].
They're outside in a coconut fibre lined basket filled with more loose fibre and sphagnum moss and to my amazement are actually putting out roots despite the cold weather here in Victoria.
I am going to have to move them for the winter though as they have no protection from the rain.
Whatever your NOID is, it looks very healthy
Regards
Damian.
