Hydroponic culture in the kitchen

Hello, I am kimono. I was interested in growing plants by hydroponic culture in the kitchen for several years. Finally I started cultivating from March of this year!
I bought a kit for hydroponic cultivation. As the tomato stem became bigger, I took it out of the container and replaced it with a glass vase. Then it grew bigger and gave a fruit. My son and my husband are looking forward to observing the growth of tomato every day.　Tomato growing from seeds by hydroponic cultivation got a fruit. When is this tomato eatery?
