Throughout our many
years in the Hydroponic business we have come across
many
varied and interesting questions
regarding techniques and tips on plant growth.
It is you , the
customer, who supply the many questions, and even some of the
answers.
It is in
our own interest to attempt to find answers to the
questions.
We will be posting some
of the more frequently asked questions here in the hope they
will
assist and inform
others.
Some of the answers given to the following questions
are not necessarily everyone’s opinion. These answers are just
a generalisation and not a hard and fast
rule.
Question
1 :
What is the
best way to deal with spidermites. ?
The use of
predators is always a good solution. These are introduced to your
plants whereupon they will attack and consume the mites. Once all
the mites have gone, the predators then consume each
other cannibal style.This is not a suitable method during
the plants flowering phase as this mimics Autumn/Winter
period whereupon the predators will go into
hibernation.
The
most recent effective method is spidermite
control.This can be applied as a
safe non-toxic spray and can be used at all stages of your plants
growth, up to 14 days into the flowering phase.
Question
2 :
How do I
prevent and control Pythium. ?
Prevention.. Keep
your grow system absolutely clean. Treating the
incoming
water against this
fungal infection should be at the forefront of every growers mind .
A clean and well maintained growing system will combat the
infection.
You can create a
balanced Eco - system by applying beneficial bacteria throughout the
whole cycle of your plants. This will put the
beneficial bacteria around the root-zone, which in turn help
prevent any other non beneficial bacteria from prolifferating and
causing any harm to your roots.
If growing
Hydroponically, it is advisable to change your
nutrient solution completely once a week. It is
also reccomended, if growing in Rockwool slabs to use one
of the many Enzyme preparations to break down any waste organic
matter that Pythium will use as food. It is not reccomended to
use liquid oxygen alongside these as it will kill the live
bacteria.
Control.. There are a number of additives on the market which will
eliminate this problem and limit the risk of fungal infection.
Ultimately the systematic cleaning of your system is
paramount.
Question 3 :
What is the best conditions for
rooting. ?
Firstly , the ideal
temperature is around
23°C
and 28°C and best supplied
from underneath , a good way to do this is with a heated propagator.
The temperature needs to remain constant throughout which will
encourage root cell initiation.
Secondly, the humidity is very
important as the little plants have no roots to begin with and
maintaining high humidity around the leaves to protect them from
wilting until new roots appear. A mini greenhouse effect is ideal,
such as a covered propagator. Regular misting is also very helpful
for the young plants.
Finally, light is essential to the young plants from day
one. Some form of filtered sunlight is fine, however the use of
fluorescent horticultural lighting is recommended . Light should be
applied for at least 16hrs a day.
Question
4
:
Is
hydroponic produce as healthy and nutritious as soil
grown
food
?
Hydroponic produce can
be every bit as good. Hydroponic nutrient solution are blended
from mineral salts and are formulated to contain all the
mineral elements required for plant growth. Green plants can only
take up elements and are exactly the same whether from manure or
nutrient solution.
Some recent research has
confirmed that the food value of Hydroponic produce is at least
as high as the soil-grown alternative, and in some cases far
superior.
In
Australia,Hydroponic food stuffs
command a higher retail price.
Question
5
:
How
do I measure pH in my system ?
This can be done with a
meter, but there are various kits using liquids and paper.
These kits are adequate for systems such as pot culture, whereupon
the nutrient is added to the plants Once and is used up
before re-filling.
Using the
re-circulation systems such as NFT or Ebb and Flow may require a
meter to monitor their solution regularly.
Over correction of
Ph can be counter productive ( stressing the plant ), A
wandering Ph between 5.5 - 6.5 in Hydroponics should not
necessarily need correcting.
Question 6:
What different type of systems are there
?
There are many types of growing
systems available in todays market place. Here are just a few to
mention.
1: Aeroponics.
2: Ebb and Flow.
3: Flood and drain.
4:
N.F.T.
5: Deep water culture.
It is the growers choice to choose
the best and most practicable system to meet their
needs.
