Hi all. Question on amount of salinity in water. I have several rainwater tanks . I collects off the fiber glass orchid house roof and the other of a colorbond coated steel roof. After infrequent rain, the salt reading are around 120 PPM. Normally after frequent rain it is around 20 to 30 PPM. I live about 500 meters from the sea and usually get sea mists nightly , resulting in salt being deposited on the roof.
Would would the normal level of salt be in the water before becoming toxic to orchids. Cheerio Ron Boyd _______________________________________________ the OrchidGuide Digest (OGD) [email protected] http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
