I ended up just going with 100% MVP Turface, and im going to top water when it looks about dry. I figure this will prevent crown rot. Hopefully this substrate is as good as people say! lol
I know the feeling...but honestly, you shouldn't worry so much about crown-rot. It's not that common. You have to be doing something REALLY wrong to have a plant succumb to something like that. You're going to be fine.
