Hydroponics is a form of hydroculture and a subset of hydroculture which involves growing plants without soil, by using mineral nutrient solutions in an aqueous solvent instead of hydro grains.
Most of the time we usually think of placing cut flowers in water and rooted plants in pot with soil however certain plants can also continue to grow in water and thrive completely without soil.
One kind of hydroponics involves rinsing off the soil from the roots in lukewarm water and placing the plant with roots intact in a vase of mineral water just enough to cover the roots. This method is very modern and trendy and lets you enjoy watching the root of the plant grow, a practical way to enjoy plants indoor as you won't have to water nearly as often.
Plants that will grow well in just water are:
While a plant grown hydroponically requires watering less often, that doesn't mean you can entirely eliminate the need to care for it.
Mineral water helps feed the plant as they need these minerals to thrive and prevents limescale from forming in the vase.
Clean the vase and replace the water monthly. You can add a few drops of houseplant fertiliser to the clean mineral water to enhance the colour of the leaves.
The best place for the plant is in a well lit space (filtered ok) and away from direct sunlight.
