How does grey water affect the growth of seeds?

Question

Please explain CLEARLY

Answer 1

Gray water" is wastewater collected from clothes washers, bathtubs, showers, and laundry or bathroom sinks. If properly collected and stored, it can be safely re-used, thereby reducing fresh water consumption. Reuse of gray water can also reduce the load on septic tanks and leach fields.

Gray water is distinguished from "black water", which is wastewater from toilets, kitchen sinks and dishwashers. Black water should never be reused in the home because of possible contamination by bacteria, viruses, and other pathogens.
