Houseplants - No soil needed

If you have a hard time following a watering schedule, which can ultimately lead to the death of your plants, consider growing your greenery hydroponically, instead. Many popular houseplants, like monstera and philodendron, can grow in a container of water without soil. Simply put the roots of your plant into water—making sure the foliage isn't also submerged—and watch as they flourish. While these growing conditions aren't suitable for every type of houseplant, there are a few beautiful options that can thrive as hydroponic plants.

Thoughts about these plants?

My mom used to start new plants by rooting them in water and once the roots were growing well, then she'd transplant them into soil. I think that sometimes the water gets really icky and starts to smell, from what I remember, but maybe there is a way to combat that problem?
