Salt for Plants?

Is aquarium salt harmful to plants? Specifically I am worried about a clump of hornwort.
I'm planning on adding the salt at 1-2 tsp per gallon, (if anyone uses a different dose let me know).

Any help would be appreciated.

Go ahead and add it to the tank. Many plants are very sensitive to salt, but some are tolerant of it—hornwort being one such example. I've kept it with mollies at a concentration of 1 Tbsp. per gallon (mollies being euryhaline, that's not a problem for them—it's perhaps a bit too salty for purely freshwater fish); it's perfectly happy. Other good choices for slightly salty water are Vallisneria, Java fern, Java moss, Lilaeopsis, and some Echinodorus.

I did a column on brackish-friendly plants a few issues back; you might want to look at that for more info.

Hornwort should be able to tough it out without issue, do you have other plants in the tank as well?
