yeah I am using LECA as well converting most stuff to
SH or anyway use LECA mixed with a little bark.
All seems OK except a Den formosum that was thriving and after a few weeks in LECA no new roots and yellowing leaves. put it back in bark and now I hope for the best.
I have Sphagnum and I would repot the Max in it if it is better. since i got t seems ok but no new growth...
wonder if it has to be moist all the time.
