Hi, Miller. My plants-I have half a dozen, all different species, plus a couple of schombo-Catt hybrids, are all in the pots used when first purchased, between four and 7 years ago. They hang out now with masses of aerial roots. Potted in bark and perlite - never yet repotted. Every few weeks dunked in a large bucket of my standard mix at pH6 and EC450. Three layers of shade cloth on the greenhouse roof. Currently in a marvellous summer, temperatures up to 35 by day, down to 17 by night. What else can I tell you ?
