mix of orchids

[Niffer]

here goes, I want your opinion on how i did. ive heard so many different things about orchids and the different care they need that i need some advice.
I have some Phalaenopsis the ones that i'm most concerned about have no tag. they have lots of arial roots and when i got them they were in a northeast facing window. he has had them nearly a year with no flowering.
5 for 15 dollars. when i got them home i put them in a bark, perlite, and charcol mix. They seem to like the change as the old stuff in the pot looked like it was very old. now here is my question, I need to know how often i should water. some are not in clear pots. I am in the pacific northwest with a 8b zone. they are placed in a north facing window because i do not have a east or west facing i can use. I tend to over water and do not want to water these to much but don't want to underwater either. ive also heard if the arial roots start to wrinkle it is time to water. is this true? There has also been some mix of idea's that i have seen. some like the moss while others like the bark mix what is the opinion on this subject. thank you. They all look healthy i would like to keep them that way. first picture is when he had them. it will not let me download the pic of now.
