I vote for repotting into hydroton!!! I have a sharry baby in S&H right now and it just LUVVV's it!! It has maniac roots all over the place inside the container.Its a great way to keep their roots hydrated yet give them air and root growing space. Just repot it, remove as much dead stuff as you can and all the dead roots, repot into hydroton and keep it in a low intensity light area for 3 weeks, then slowly increase light levels. Go for it!!
