I don't know how I didn't think of this before, but recently I connected a hose to a downspout that drains condensation from my house's air conditioner. I reposition the hose every once in a while to water a new area. It currently is flowing about a few drips per second, which keeps the spot it feeds pretty moist for 95 degrees outside. Originally, I was wondering is this safe?, but I found a few articles discussing this use of AC condensation water, and now I just want to encourage others to take advantage of this if you have it.

Here is one site that mentions the use of AC condensation water, with no warnings:
http://landscapeforlife.org/water/use-alternatives-to-municipal-drinking-water-for-irrigation/

This article mentions an issue with a certain microbe (Legionella) and it should only be used for sub-surface irrigation where it can't be aerosolized, where it might be inhaled and affect human health.

Another use of this technique:

I just hang a hose from the pipe tied on with some hemp rope, so I can see the flow level and easily remove it if needed. One place estimated about 3-5 gallons per day from this, but I assume it will vary on AC use and air moisture content.
