Since I can't seem to be able to find any form of sphagnum moss, I've been forced to find other alternatives. For the ventricosax(rafflesiana x tobaica purple) and rokko x spathulata that I just got, I used a medium with peat, vermiculite, and perlite at about a 1:1:2 ratio. Anyway, the perlite seemed to float to the top when I watered it, and it took forever to drain. Is there something wrong with the medium? Or is it all right, and unecesary to repot again?
