For example in hydroponics, the plant root has only water… where does it get the extra matter it needs to make more plant cells so it can grow? How does water turn to plant?
Hydroponics isn’t just water but also nutrients, essentially the plant version of Flintstone vitamins.
If you picture a balloon arch. Plants pull CO2 from the atmosphere to make the balloons, and then fill them with water. They use those vitamins to perform those activities.
