Abstract
Observations on the effects to cut flowers were made using bisque fired ceramic balls (patent pending 2002-382862). Tests have indicated the presence of H- created during a hydrogen (protium) generation process when the ceramic balls are immersed in water. When the balls are placed into tap water, the ORP of the water becomes about -250mV and the pH about 10. This reduction reaction is maintained for more than 90 hours.

Experiments with different numbers of ceramic balls and cut flowers treated with blue dye indicated the concentration of hydrogen ions generated by the ceramic balls influenced plant circulation. Flowers placed in 200ml of plain water, 200ml plus 0.65g of ceramic balls and 200ml of water plus 0.8g of ceramic balls showed significant differences in plant circulation with 0.8g giving the strongest circulation response. Hydrogen's influence on this mechanism is now being examined.
