The tale was about how someone bought a hydroponics tomato growing kit that produced about 15 tomatoes. Once they figured the cost of the kit, the electricity for the light to grow the tomatoes and the time they put into to growing the tomatoes, it cost them about $15 per tomato. And these were cherry tomatoes.
