Your catts look very good. Below is a picture of my Blc. Mari's Glory and a Leptantes bicolor. I sent the picture of the roots of the Blc. to H. of H&R, the hybridizer and he could not believe that such a small root mass produced two perfect flowers.
Sharry Baby definitely prefers water culture as you can see from the pictures.
Your Sharry roots also look good. If I were you I would put on rubber gloves and clean up the decaying roots and stuff and raise the plant a bit to give more room for root development.
About the Phal., I just have to remind you that I have never been successful with them in water culture. There is a long thread on someone trying phals. in water culture in the Semi Hydro forum but there is no feedback on how he made out.
