@frostedeyes: I know the bottom does not look pretty, but it is not the crown, and it's not rotten, it has been in water culture with just the bottom of the plant. The crown is always dry and has produced two little new leafs and what you are looking at is the plant upsidedown Iam leaving in in water culture as it was an exsperiment in the first place and it has turned this phal into a champ and it is now grow three roots
as compared to it no roots. Thank you for your ideas anyway!
