Here's the only advice I've found - from the Daily Mail (lol)Can I ask you, what does soap do to microbes? Even in small amounts? Will this help the microbial multiplication, or hinder it?
P-
Q I use my washing-up and bath water to water my patio plants. My husband says that so much soapy water is not good for them. Is that right?

A In principle you are doing the right thing, although your husband is also partly correct. In fact, the potential harm is less to the plants than to the soil, with its complex bacterial and fungal make-up. Recycled soapy water (‘grey’ water) is perfectly usable for plants, but I would not use it exclusively. Rotate it with ‘clean’ water on an alternate basis and, as with all watering, direct it at the roots rather than the foliage.

Scroga,
Soaps are the salt of a fatty acid - there is going to be some interaction with the life in the soil. In a chemical grow it'll matter less. In an organic grow it's clearly not going to poison anything off the bat - keeping in mind dilution and frequency of application.
It's not just about the soil - there's a symbiotic relationshiip b/t the plant and critters in the dirt, with the plant's roots actively controlling the fungal life around it. For that reason I sure as hell wouldn't use it in a grow, but maybe a lawn. It'd be a fun trial to run to see how a grey-watered plant fared - I'm guessing a little slower and little smaller from lower food availability.
Worst case would be something like what I've seen using sodium benzoate on a couple of rooted clones. Did it to see what'd happen (bought wrong bottle of aloe, lol). A complete stall of growth. I've dosed with ACT and SST repeatedly to get things moving, but four weeks later and so far no bueno - plants still 4" high. I fucking love these learning experiences, haha.
