Maybe this is a pretty dumb question ,but does condensation water from the A/C contain any salt when living on the ocean ? Can it be used to water
houseplants ? I remember watering the plants with water that went through the softener and it pretty much killed every one of them. Never even gave
that one a thought. Now I need to know before I maybe kill them again

The only minerals it would have would be from any dirt it picked up as it left the A/C. It would be basically the same as rain water.

Not sure about the ac, but I do use the water from my dehumidifier.

I ran a hose from my heat pump condensation pipe to one of my Cape Honeysuckle plants. It's doing much better than any of the other plants. We have
no grass, just sand. We're in the dunes but a long way from the ocean.

The copper fins from the AC condenser may contribute extra copper to the water but I doubt if it is enough to harm the plant.

The coolness of the condensor will concentrate the humidity in the air and whatever particles it contains - dust -salt etc.
Probably a good indicator of the water purity would be any visible corrosion that develops on the condensor. In short ,the answer to your question is
yes but the most important question is how much and are your plants sensitive to it
Let some of the water drip onto a clean piece of glass and the let it dry to get an idea of the amount of included minerals
