Using Dehumidifier Water

Post  gspoerke on 6/8/2018, 2:54 pm

I have just read in the forum about the use of air conditioner water and water from a heat pump. I was wondering about the use of water from dehumidifiers for the vegetable garden. Has anyone tired it?

It is generally safe for plants. A/C water can also be used.

Re: Using Dehumidifier Water

Post  BeetlesPerSqFt on 7/22/2018, 4:16 pm

I use dehumidifier water on my houseplants sometimes - but I don't use it where I grow vegetables because my understanding is that there can be lead in the soldering joints that connect the parts inside the machine. I also guess there's copper somewhere in mine because there are green stains (it's not algae) where a off-center drip has repeatedly fallen and dried. I've also heard aluminum and zinc mentioned. But I haven't been able to find actual numbers-based information on how concentrated these metals get... just variations in how much people use capital letters in discussions... so I don't know how much of a problem this really is. It probably varies from machine to machine, even. I'd guess it's probably fine to water decorative plants with occasionally, but might be a problem if you are watering the same spot all the time, especially if that spot isn't getting much regular water to dilute any concentrates. (I'll also mention I wouldn't drink the water -- plants don't care about the bacteria and fungi in the water, but they can be bad for people/pets.)
