Growing a plant in water is somewhat easier, no worries about under- or overwatering and it's a pleasure to see the roots grow.

1-Can 'any' plant be grown in water? From what I read soil is mostly to provide nutrients and if you can add fertilizer to water then you can grow almost any plant in water. It seems to me that the ones usually lised as plants that can be grown in water are the ones that do not require fertilization. For example ficus and dracaena are not usually listed as plants that can be grown in water but upon a little internet search you can find pictures of them growing in water (albeit not getting that big).

2-Is it better to let a stem cut grow roots in water? Again this way you don't need to worry about giving the stem cut enough water. The particular plants I have in mind at the moment are croton petra and money plant.

3-Can you use brewed coffee, in small amounts, as fertilizer when growing plants in water? I've read that some people use brewed coffee as a fertilizer.
I need to travel to a nearby town to get liquid fertilizer and that's why I ask. :=)

In many locations, all kinds of plants are grown hydroponically, meaning in water solutions. I suggest that you do a search under hydroponics to learn more about how plants ca be grown permanently in water. You will need special hydroponic nutrient solutions rather than home-made nutrient sources.
