ABG mix and live moss help!!

[Frog]

Im about half way through my 40 gal vert build; my question is, im looking for that fantastic moss covered/carpet look, but have heard that ABG substrate is pretty much the best to use because of how sustainable it is. will i still get that moss carpet im looking for using ABG mix or will the moss have a difficult time attaching to this very porous substrate. want to use either java or riccia moss. Thanks for any input!!

both will work just fine in abg mix. java will just need to be kept moist for the most part. riccia will like it closer to soaked.
