Here’s what the substrate looks like now! I’m probably gunna add one more bag of organic potting soil. One part sand, half a bag reptibark, one part sand, one 8qt bag of spag moss. What do you think?
I did that! The balls are in the root bag alreadyYou´re gone put this on a drainage layer? That´s really imported, you could use a layer of hydro- / clay balls (i.e. https://zoomed.com/hydroballs/) with a thin separation layer (i.e. https://zoomed.com/naturalistic-terrarium-substrate-mesh/) and then on top your mixture.
