What levels of Sodium and Chloride are "safe" for orchids??
Hi all!
I recently had my water tested by a lab and found that the Chloride concentration was 146 (mg/L) with the Sodium at 184 (mg/L). Hardness was <10 with a pH of 7.3. There were really no other minerals of note.
Now, while these values for the Sodium and Chloride ARE under EPA maximum recommended concentrations for DRINKING water, will they have any adverse effects upon my orchids - mainly Catts, encylias and Zygos??
Thanks for any info or direction!
