I forgot the growing infos:
It likes good pure water very much (as for Phrags), with low salts and not too alcaline.
As it needs to be watered very much, with high humidity and quite high temps the whole year, it's better to use a very well drained medium, or like me, rockwool growcubes are perfect (no rot when watered a lot)
This one is grown under lights (neons)
