“What’s in it for me?”
• If the next 80 minutes go as planned, you
will leave this room convinced that you’ll
never again plant a seed or root a plant in
soil!
• You’ll learn what Hydroponics is, where it
came from, what shapes it comes in, and
where it’s going.
• You’ll also build your own, fully
functional hydroponic garden to
further stimulate your newfound
desire to incorporate soil-less
gardening into your classroom!
WHAT IS HYDROPONICS?
• “Hydroponics is a method of growing
plants using mineral nutrient solutions in
water, without soil. Plants may be grown
with their roots in the solution only, or in an
inert medium such as perlite, gravel, rock
wool, or coconut fiber.”
WHAT DOES THAT MEAN?
• It means, Hydroponics is all about growing
plants without putting them in the dirt.
• The idea is, soil-or dirt presents a variable
that is, at best, difficult to control. By
eliminating that “dirty variable” we can
provide our plants with optimum growing
conditions and high volume production.
What CAN we
control?
Quantity of light
Duration of light
