Thank you
@Gina1960,
Right now the soil is about 40% perlite, 60% potting mix.
I'll try with something like 20% potting mix, 20% perlite, and the remaining 60% I'll mix bark, lava rock and LECA.
That should give a small base of water retaining soil, and then lots of air pockets where the roots can enter. How does that sound ?
