Sphagnum Moss vs. Orchiata Bark

[netrizone]

Hi all, in one of my previous posts, many of you guys recommended that frequent watering was the key to faster vegetative growth.

As one of my phals are due for a repot (it's currently sitting in broken down moss), I was thinking of the benefits of repotting it in New Zealand AAA moss vs Orchiata Bark.

Of course, orchiata bark dries out faster than moss, so I would have to water it more. This should make bark better than moss if I want faster vegetative growth, right?
