Hydroton & CHC mix for phals?

[Izzie]

Was pleasantly surprised to find that my local Home Depot just started carrying "hydroponics starter kits", which are nice, but more importantly, reasonably priced large bags of Hydroton LECA! (~$9 for a bag half my size, didn't look at the weight.)


I'll be repotting most of my phals soon after they get around to letting their buds actually open and finish blooming. it's taking forevvvveerrrr.

I was going to try a mainly CHC mix with bark and charcoal, but how would a CHC and Hydroton mix do? (with a little charcoal, already mixed in the CHC)
I'm paranoid about overwatering, and I live in a dry environment.
I feel that this mix would be more forgiving if I "overloved" my phals from time to time.
Or, to phrase differently, I'd rather have to water more frequently than be uncertain about watering less often, if that makes any sense. (not to say that I'd have to water more, but I'm rambling......)
