grammatophyllum scriptum potting mix
 

What do you guys like for potting mix? I'm putting it in a 12" metal hanging basket with a moss liner.

I have CHC, hygromite, hydroton, pumice, AAA moss, and med. fir bark here. But if theres something better I'll buy it!!!!

I don't plan on repotting this plant after this for many years.

Thanks for your input!!!!

Gramm. scriptum
 

From the little I know about Gramm. scriptum, I suspect your "many years" may become a "few years" as it is a very vigorous grower, quickly becoming a large plant if the one I have is any indication.
For long term potting, I would suggest something that doesn't readily break down.
