To maximize plant growth, the pH level of
your nutrients should be slightly acidic.
Experienced growers consider the ideal
pH for most crops to fall between 5.5
and 6.5. Users of General Hydroponics
nutrient products generally do not
experience problems maintaining the
proper pH range because our formulas
are pH buffered. However, some
important exceptions do exist. pH can
acidify to an unacceptable level when
nutrient solutions are used with poor
quality water, or pH unstable media, such
as rockwool. High growth rates can also
destabilize pH.

The Essentials of
Successful Gardening
Genes
The genetics of your plants will play a major
role in the outcome of your garden. As
the plant goes through its life cycle it can
sometimes be difficult to assess whether
the plant is responding to its environment,
or whether it is following the instructions
written in its DNA. With the rise of GMO
crops, the choice of which varieties to grow
can become a charged issue. Engineered
species may be more hardy and pest
resistant, but might also be flavorless,
or have an unexpected interaction with
the environment. Whether you choose a
resilient modern variety or an heirloom with
character, remember that DNA will always
be working behind the scenes.
Atmosphere
The atmosphere affects the growth and
life of plants dramatically. Plants require
lots of fresh air, so growers who are
using greenhouses and indoor facilities
must supplement their airflow with fans.
The temperature and relative humidity
have a major effect on plant physiology
and growth. Both photosynthesis and
transpiration are dependent upon proper
humidity, temperature and air circulation.
Plants can survive in a wide variety of
atmospheric conditions, but to truly thrive
they must have plentiful fresh air and
proper temperature and humidity. The ideal
temperature and humidity for your plants
is between 65 - 90˚ F (18 - 32˚ C) and 40% 80% relative humidity.
50
Light
The amount and quality of sunlight that your
plants receive will also affect their growth.
Seasonal variances, exposure and shadows
from buildings and trees must be taken
into account when setting up a garden. If
artificial light is to be used, it must be of
a robust spectrum and sufficient intensity
to satisfy the needs of the plants without
overwhelming them or drying them out.
Different plants and different phases of
growth require different light spectra and
intensity. Light supplies the energy used
in photosynthesis, which is one of the most
fundamental plant processes.
Nutrition
Plants need nutrients to grow. GH has
several nutrients which provide all of
the elements required by plants. These
fertilizers contain an idealized blend of
macro and micro nutrients, and can be
adjusted to suit the needs of the plant
based on its age and growth stage. To boost
plant performance, successful gardeners
add supplements to the nutrient solution.
These additives can improve plant vitality,
enhance flavors, and increase yields.
Since these nutrients and supplements are
absorbed through the roots of the plant,
optimum nutrition requires strong and
healthy roots. Proper nutrition is a major
component to healthy, thriving plants.
Water
Pests
Unfortunately for gardeners, there are
a host of organisms which survive by
destroying plants. These range from
microscopic bacteria, viruses and fungi
to larger organisms, such as insects and
arachnids. Cleanliness can help prevent
pests from arriving. By keeping garden
tools and surfaces sterilized, destructive
microorganisms will have a harder time
gaining a foothold. Moist, warm and damp
conditions are favorable to developing mold
and mildew, so avoiding condensation
and insuring sufficient air circulation will
help keep these undesirables away. Larger
pests require a more aggressive approach.
There are many products available which
assist in the eradication of these invaders,
but cleanliness is a good start in managing
pathogens and pests.
The quality of the water that plants receive
will affect their health and vitality. Municipal
water can contain harmful additives, such
as chlorine, and even natural well water
can contain an excess of minerals or have
an extreme pH. A surplus of many common
elements in water can cause a chain
reaction in a nutrient solution, resulting in
many of the vital elements fusing together
and becoming unavailable to the plant.
Testing your water will inform you if your
water is a problem. If your problem is
excessive minerals, using Flora Series and
Hard Water Micro might be sufficient. Truly
problematic water must be filtered or pH
adjusted before being used for plants.
51
Advanced
Growing Techniques
Nutrient Strength
and Meters
Nutrient strength is a key factor in proper
plant nutrition. Although the recipes GH
provides you should create nutrient solution
at the proper strength, there are many
environmental factors which can cause
nutrient strength to change. A nutrient
strength meter is an essential tool for the
advanced grower.
There are two different types of meters
which measure nutrient strength; PPM
meters and EC meters. Both types make the
same measurement, but then present the
result in different units. Nutrient strength
is measured by passing an electric current
through the solution; the more easily
electricity travels through the solution, the
stronger it is. An electrical conductivity
meter (EC) will give this result as an
electrical value, such as a milliSiemen
(mS). This number is directly related to the
strength of the nutrient.
PPM meters measure the conductivity of the
solution, and then attempt to estimate the
actual parts per million. The problem with
this method is that different meters may use
different scales to convert EC measurements
to PPM readings, so two different PPM
meters could read drastically different
values in the exact same nutrient solution.
A PPM meter is still a useful tool to a
gardener, but it is important to know that
different meters use different scales, and
that 500 PPM does not always mean 500 PPM.
Knowing which scale your meter uses will
help you avoid underfeeding or overfeeding.
If you get advice about PPM values, be aware
that they might not translate directly to your
garden. Using an EC meter will eliminate
PPM confusion, but used properly, any meter
will allow the gardener to track changes in
nutrient strength and make decisions and
adjustments which will contribute to success.
52
Heat & Nutrient
Arid, bright, hot environments can have an
impact on nutrient solution. As the solution
loses water through evaporation and plant
transpiration, nutrient strength increases.
When growing conditions are more intense,
using a less concentrated nutrient solution
and monitoring nutrient strength with a
meter can help prevent overfeeding. As
nutrient solution becomes warmer in hot
weather, it loses it’s ability to hold dissolved
oxygen, which is essential for root health.
When hot weather strikes, monitor the
solution temperature and keep it
below 75˚ F.
Meters for measuring nutrient
strength are available as either pen
style or continuous meters in both EC
and PPM formats.
Calibrate meter to a
standard reference
conductivity solution
weekly or as needed.
If you are unsure which scale your
PPM meter uses, measuring a standard
reference solution can help you to
identify the scale.

Specific Nutrient Deficiencies
Hydroponic nutrients contain all elements needed by plants. Under normal circumstances,
all elements should be available and nutrient deficiencies will not occur. A pH imbalance
can cause nutrient deficiencies by creating mineral interactions. Hard water or incorrectly
mixing nutrients directly together will also contribute to pH problems. If you observe signs
of a specific nutrient deficiency while using high-quality nutrients, examine environmental
factors first.
pH & Nutrient Availability
The pH of a nutrient solution describes its acidity or alkalinity. Although extremes of
pH can damage roots, the primary reason that pH is relevant to growers is that it affects
whether certain elements in the solution are available to the plant or not. Specific nutrient
deficiencies can arise in a well balanced nutrient solution if that solution exceeds the
optimum pH range. Therefore, it is beneficial to your plants to monitor and adjust pH as
needed to ensure complete nutrient availability. Many factors work to change the pH of
your nutrient, including microbial activity, atmospheric interactions and recirculation. For
best results regularly check pH to ensure that it does not exceed the acceptable range.
Keep nutrient pH between 5.5 and 6.5.
A pH test kit is the most
economical method for
measuring nutrient pH.
Electronic pH meters are
the quickest and easiest
way to monitor your
nutrient pH.
Calibrate
meter to pH
7.0 calibration
solution weekly
or as needed.
Add pH test solution
to nutrient sample and
match color on bottle to
measure pH.
For increased
accuracy,
calibrate meter
to pH 4.01
calibration
solution.
Use GH pH adjusters to raise or lower pH as needed.
Adjusters are available in liquid and dry formulations.
Add adjusters gradually to avoid overshooting.

Why Use
Hydroponic Nutrients?
Providing superior results in both soil
and hydroponic gardens, hydroponic
nutrients are mineral-based plant food
which provide complete and total
plant nutrition. Because hydroponic
systems do not use soil, they rely on
the nutrient solution to provide all the
elements needed by the plants. As a
result, hydroponic fertilizers, unlike most
commonly available plant food, must
contain the entire spectrum of necessary
elements, making them a robust and
complete nutrient source suitable for
all gardens.
Typical Fertilizer
(Unsuitable for Hydroponics)
This fertilizer only provides partial nutrition and must be combined
with other fertilizers and soils to provide complete nutrition.

The nutritional needs of your plants
will change throughout their lifetime. A
seedling needs a completely different
nutrient than a flowering or fruiting plant,
and due to their precise composition
and modular components, hydroponic
nutrients can easily be tuned to match the
needs of a plant at any stage of growth. In
addition to supplying complete nutrition,
hydroponic nutrients are also easily
customizable and adjustable to match the
changing needs of your plants.
Soil or hydro, hydroponic nutrients provide the ultimate
in comprehensive and customizable plant nutrition.

The Role of
Supplements
Although properly mixed, high quality
hydroponic nutrient will provide everything
a plant needs to thrive, plant performance
doesn’t end with supplying just the
necessities. Plants cannot live without
nutrients, but nutrients alone will not
unlock their full potential. Even though
supplements may not contain “food” for a
plant, they improve a crop by performing
such functions as introducing essential
organic compounds, accelerating nutrient
uptake, boosting blooms, protecting the
root-zone and clearing excess unused
nutrients. Enhancing a garden is easy
when working with the supplement options
available from General Hydroponics.

About
General
Hydroponics
During the nineteen
seventies, an inspired
group of scientists,
engineers, and
technicians came
together with a common
goal: to advance
agricultural technology.
Together they created General Hydroponics
a company that now – over thirty years later
– leads the industry in developing innovative
hydroponic technologies and plant nutrients.
With facilities in North America and Europe,
General Hydroponics products are available
through a global network of thousands of
dealers and distributors. And because we
recognize the multilingual nature of the
hydroponics industry, we are proud to have
staff members fluent in several languages.
Plant researchers at numerous universities
522
7
and commercial laboratories throughout the
world depend on the high quality of General
Hydroponics products for their research. Our
commitment to providing these professionals
with products of the utmost quality extends
to all our customers. Our dedication to
assisting researchers and consumers alike
makes General Hydroponics the hydroponic
systems and nutrient manufacturer you can
trust to help you care for your plants.
Our premier North American manufacturing
facility is located in sunny Sebastopol,
California, where the famous horticulturist
Luther Burbank developed thousands of
new plant varieties. General Hydroponics
operations cover ten acres, providing an
ideal environment for testing new crops,
hydroponic systems, nutrients, additives,
and related technologies. The factory alone
consists of over 50,000 sq feet (4,600 sq
meters) of modern industrial space for
the development and production of new
hydroponic technologies. In addition to
our Sebastopol location, we have added a
manufacturing facility in Martinsburg, West
Virginia to better serve the eastern regions.
General Hydroponics employees experiment
with new hydroponic system designs and
methods in our large on-site greenhouses.
Recent innovations include the use of alternate
energy sources and the implementation of
nutrient/water saving technologies. Because
General Hydroponics remains committed to
aiding in the global struggle for a cleaner,
more environmentally efficient planet, we
continue to develop advanced systems
powered by solar energy. In addition, we are
currently developing innovative filtration
systems to control plant pathogens, as well
as new growing media that include organic
components and revolutionary nutrient
formulations. All of these products are
designed to enhance flavor, yield, fragrance,
and essential oil production in vegetables,
flowers, culinary herbs, and medicinal plants.
General
Hydroponics
is
continually
developing improved plant nutrients that
enhance the vitamin and mineral content
of food crops, which in turn ultimately
improves human and animal health. Our
farm division has tested over one hundred
plant varieties for growth-rate, yield, flavor,
nutrition, appearance, shelf life, fragrance,
disease resistance, and hydro-viability. We
perform side-by-side tests comparing a
number of different hydroponic techniques
with traditional organic methods in order to
determine how best to grow top-quality crops
hydroponically.
General Hydroponics has never lost sight
of its goal to expand the boundaries of
hydroponic technology, and to lead the
industry in quality and innovation.
