Growing Flowers using Hydroponics

I haven't tried any flowers with Hydroponics and don't have much idea on this as never seen them anyone here. If flowers can be grown using Hydroponics, then we will have great profits and life will be easier.
To the extent I realize Carnations are the top flowers that can be developed hydroponically and they give a lot of benefit in the market. I haven't attempted, yet observed some place locally here . These flowers can be become so quick and they make some great benefit to the cultivators.
So does these carnations grow fast and they can even sell in the market fast? I have never heard such things or never been a member in Farming groups. It's nice to hear that we can make some easy money from Hydroponics by growing fruits, vegetables and flowers too.
