David, your All-Terrain rider is no chemist. Check his pH desciptions: " 4.5 or below (very acidic) 4.6 to 5.0 (highly acidic) 5.1 to 5.5 (strongly acidic)".
Following this system, you'd soon arrive at: pH 7 (strips the skin off your hands). Peter O'Byrne Singapore _______________________________________________ the OrchidGuide Digest (OGD) [EMAIL PROTECTED] http://lists.orchidguide.com/mailman/listinfo/orchids
