Chroms right on the distilled water thing. Water is the universal solvent. Use tap or spring, just check pH.
-- On the oil slick from your run off.. don't know exactly what it is (Weeze or Chromophore can chime in here), but it ain't good. Dude. After you let the plant sit in water, you should have run more water through it to rinse away what you just disloved. Next time, just let it dry for now.


P.S. I like Jorge, but don't always agree with him.
