What are Hydroponics?

Hydroponics are culture landless, it
coltivated on inert substrates with root
plants immersed in a nutrient solution
where there are elements necessary to
growth.

NFT

In NFT sistem roots of plants are
immersed in a subtile films of nutrient
solution where plants take nutrient for
growth.

DWC

In DWC sistem roots of plants are steadily
immersed in a nutrient solution but this
solution is also peroxide by a oxygenator
so the plant don’t suffer root asphyxia.

Ebb Flood

In Ebb Flood sistem nutrient solution often
is removed and put back to avoid root
asphyxia, ensuring a good oxygenaion to
culture.

Drop

In Drop sistem nutrient solution is
pressure in a small pipes and each
pipes is connect by a plants to
supplying.

Nutrition

The solution utilizzated for
hydroponics is composed by
macroelements (N,P,K) and
microelements (Ca,Mg,S,Fe,Br,Mn) in
minour amounts, at times not
present in solution.

Quality


3.
The quality is greater to tradizional
culture because the crops are:
Organically perfect
Healthy
Usually don’t affected
by diseases

Diseases

The diseases are very low in
hydroponic because landless there
aren’t bacteria and virus that attack
plants. In fact there is a less use of
pesticides in hydroponics.

Weeds

The weeds in hydroponics are absent
because we use substrates where
there aren’t foreign seem to our
culture.
-Note: So we don’t use herbicides.

Profit

The Hydroponics are more
remunerative by tradizional crops
because with this method we can
achieve production 2 to 10 times
more.

Ripeness

The ripeness is an important factor
for market of crops and thanks to
hydroponics is possible have got
every crops indipendement of the
season, ensuring fresh produce for
the market.

Water

With hydroponics there is a big
saving water, thanks to recirculation
of nutrient solution that ensure small
losses of water.
