What is Hydroponics? Video Lecture | Biology for Grade 11

so what is hydroponics growing plants
and water without soil wait back up in
nature the soil of plant grows in serves
two purposes one it anchors the plant
from above ground hazards to to provide
the plant with nutrients it needs to
keep growing with hydroponics these two
purposes are handed off the plant is
supported by a neck pop which allows the
roots to grow through into a
nutrient-rich solution below hydroponics
was first used as far back as 600 BC in
the Hanging Gardens of Babylon one of
the seventh wonders of the world
by eliminating soil and housing the
roots directly in water the plants grown
