Can household compounds (e.g. tea) be used to promote good health in plants 

You drink half of your tea and empty  your cup into the nearest flower pot. Is it good for the plant? I have seen people pouring coffee, soda and even ice cream in flower pots. How do these substances affect the plant? Can plants consume and benefit from our food and drink leftovers? How about soaps, detergents, oils and other household compounds?

Plants need certain nutrients in order to grow healthy, can we find some of those nutrients in household substances? 

 Project description:
