hopefully I can get it to take in mineralized soil substrate..
It will, the soil is not going to be the issue if it does'nt anyway.
I got this a few months back as a hitchhiker from jazzylvr. It was about ˝" leaf with a tiny root I knew I never saw it before so I kept it and it turned into a really big bush but I ended up throwing it out because I needed the space and it's not my kinda plant. It does get a nice purplish tint to the leaves if stressed as well and it grew well in SMS.
