I used sand and peat mix 1:1. Peat is pre-soak and rinsed many times to get rid of impurities (acid and stuff). Top layer I use pure peat because I find that these sun loving fellow can get burnt if the sand gets too hot, just a thin layer.
Water using tray method only.
Contrary to what many people suggest, and they rightly done so, I couldn't find deep pots so I use normal "Baba" 105 pots and they thrived..... until I got too busy and forgot to water them- yes that is why I have none left now.
Be wary of algae and if possible get rid of moss (those green stuff) co-habitating in the same pot. The empty spots between plants are victims of algae.
