I would be hesitant to follow this advice. Volatile compounds condense in a dehumidifier together with water. It is NOT pure water. Ever looked into the catch bucket of a dehumidifier?You can collect water from a dehumidifier. Or probably use rain gutters and a barrel I would imagine.


I used dehumidifier water for my collection of carnivorous plants. It is very common for plants at least. As for pollution I am in the middle of nowhere so I wouldn't have that problem lol.I would be hesitant to follow this advice. Volatile compounds condense in a dehumidifier together with water.

The same with rain water. Yeah, if you're in the remote wilderness with limited air pollution you could do it. But anywhere near a street will give you diesel root from trucks and other pollutants.
Tap water is protected by the Clean Water Act in the US. Its standards are pretty high!
