I often see those timelapse videos of various seed placed in a wet tissue starting to grow roots and then put at the top of a water container, growing quite a lot (like developing leaves and stuff) before being put in an actual pot of dirt.
Where do those plants get the energy and stuff to grow up if all they have is water ? I’ve spent my whole life growing things in dirt directly and it works perfectly, I had no idea you could do water only…

Think of the germination process from a seed as similar to that of an animal born in an egg. Everything that animal needs to go from a single cell, to a baby animal is provided inside the egg itself. Once they hatch though, then it will need food to grow and survive. Similarly all plants need to germinate initially is provided in the seed, they just need water to activate it. So the water from the wet tissue or water container provides that. But just like the baby bird, to continue to grow and thrive after germinating, a plant needs nutrients from the soil.
