Introduction to Hydroponics


Today I am going to give you
the information you need to
know about hydroponics. For
those who don’t know what
hydroponics is, it is simply a
plant that is grown without soil
and it grows in water with a
rock called Perlite to anchor
the roots.
I will discuss: the plants to
use,germination,the nutrients,
the history on hydroponics,
and the lighting.
My hydroponics





I recently made my own system
with tomatoes.
I used decorative rocks for my
anchor for the roots and used a tub
with 2 small butter containers,2
felt strips, 2 pieces of ply wood,
and wrapped the wood with cling
wrap so no water or nutrients
would eat away at the wood and
so no water could get through.
My project was quite successful
and it is easy to make.
I got 2 stems that germinated after
the 1st to 2nd week.
The only costly thing is the
nutrients and solutions to help the
plant grow faster.
What kind of things can I grow in
my system?


The most popular
of the
hydroponics
growing is the
tomatoes, and
peppers.
You can also
grow tropical
plants in water
too.
The lighting you need!





There are many different
types of lighting that you
can get for successful
growing.
The neutral deluxe is
suitable for any stage in
plant growth.
The cool deluxe is
spectacular for vegetative
growth.
Also the warm deluxe is
good for dramatic
flowering.
HID lighting, which is
High Intensity
About the nutrients



In the soil, organic
material is broken down
to release the nutrients
and minerals.
There are 17 mineral
elements present that are
essential to plant growth.
You need to be sure to
give the plants the right
amount of soluble
nutrients for plants
success in growth.
Seed germination



A seed needs warm
temperature and
moisture to
germinate.
If you start your seeds
in a system there is
less chance of
disease.
The seeds require
light as soon as they
germinate.
Meeting the plants needs




The plant must consume
a healthy diet.
They need protection
from harsh environments.
For example, tomatoes
need more nitrogen
during the vegetative
stages rather than during
the fruiting stages.
Tomatoes grow best in
full sunlight if you
choose to grow without
the artificial light.
Where can I grow my
hydroponics?





You can use drip systems
and flood systems.
These are the most
popular of the two.
They utilize a medium
with nutrient holding
capacity that gives the
home grower a margin
for safety.
You can make your own
system.
Using natural light,by
sitting the plant by a
window will help it grow.
IN YOUR HOME
What is rockwool?



Rockwool is made
from rock which has
been melted and spun
into fibrous cubes.
Rockwool is a form of
Perlite in which the
pebbles or rocks
anchor the plant down
so they don’t just float
up above the water.
Rockwool is the most
popular medium for
germination seeds
hydroponically.


Rockwool is placed in
a standard starting
plastic tray, and the
seeds are spread
evenly spaced on the
top of the medium.
You can choose from
granulated rockwool
or loose rockwool.
Propagation



There are three different
methods to propagation.
They are seed
germination, rooting stem
cuttings, and tissue
culture.
Start with seed
germination, and rockwool is the most popular
medium for germinating
seeds.



Stem cuttings from
most types of plants
can be rooted in 7-14
days.
Oxygen is vital in
root development.
The fastest and
easiest way to root
stem cuttings is
hydroponically.
SOIL VS. HYDROPONICS





In soil, bacteria has to
break down the dirt.
Soil is not able to
produce as much
nutrients per area as the
root system takes up.
Soil loses nutritional
value.
Soil is like a host to
critters.
Hydroponics simply
looks nicer!
Organic hydroponics





Coconut fiber offers
many unique advantages:
Large oxygen capacity.
Superior water holding
capacity.
The fiber is not a
biohazard.
And is definitely not a
disposable problem

The organic
compounds are found
in the fiber which is
not found in
rockwool.
Hydroponics history






The growing of hydroponics
plants is water was described in
Egyptian writings dating back
several hundred years before
Christ.
In the 1930’s scientists were
experimenting growing plants
without soil using nutrients
dissolved in water.
It has been popularized in Western
Europe and is now used in
Holland for commercial foods.
Canada is now second compared
to Holland in food production.
Work on plants date back from the
1600’s.
The process of hydroponics
growing in our oceans dates back
all the way to when the earth was
created.
Hydroponics our future????



There are no chemical
residues or dirt on
them.
They look more
attractive and
healthier.
They are more
expensive than
regular tomatoes.
Pests and Diseases
Try to prevent algae
growth.
The common viruses
are tomato mosaic
virus, and that causes
distortions of the
leaves, also reduction
in overall productivity.
You can control it by
reducing the humidity
or by using specific
fungicides.
CONCLUSION



Your understanding of
hydroponics should be
very clear by now, by the
information I gave you.
The lighting,types of
plants,nutrients,
germination of the
seedlings and what you
can use to hold the roots
down seeing as how there
is no soil to use instead.
This concludes my
PowerPoint.
