I'm not using a gray water system yet, but just beginning the process of paving the way, as it were.
Anyone know if soap nuts - the dried drupes from a soapwort tree - safe for use in a gray water system? Are there any problems using them for plants? I wondered because I thought that saponin, what I extract from them, played a role in plants protecting themselves, so I wasn't sure if it might be problematic using it to water plants.
two quick responses: Firstly, they're probably not a problem at all. Secondly, what type of grey water system are you using?
If conventional surfactants and all the other stuff crammed into cleaners isn't a problem for a conventional grey water filter - I don't see how soap nuts would cause problems. Enlighten me if I'm missing something here - but conventional grey water us pretty gungy stuff; I'd go for the natural alternative any day if I was a filter
