Plant Nutrients

Growth Technology’s nutrient solutions are formulated with accuracy, manufactured with care, and are designed for high performance. The choice of nutrient is the personal preference of the individual grower but certain nutrients will fit certain growing media much better than others.

IONIC® Hydro

IONIC is a unique single pack nutrient designed to deliver the complex profile of mineral elements a plant needs, in an easy-to-use format.

Our research has enabled all essential elements to be combined in a single pack.  Most importantly, these are stable in solution and delivered in the correct ratios required by plants. IONIC is also pH stable giving the grower easy control over nutrient solution and trouble-free operation.

IONIC contains 14 essential elements at both macro and micro levels supporting rampant growth and superb harvests.

IONIC delivers every time.

IONIC:

  • Delivers stunning results
  • Easy to use
  • pH stable

IONIC often copied, never bettered….

A background and long experience in commercial hydroponics was the basis for the development of IONIC nutrients. Plants in hydroponic systems are entirely dependent on the solution for its nutritional needs. It has to be correctly formulated, it has to be stable, and it has to be consistent. Ionic nutrients are fully complex in the manufacturing process; key minerals are locked together in large molecules to ensure a precise delivery to the plant. As far as it is known, this is the only product in the world that is formulated and manufactured in this way, and to this supreme standard of precision.

State-of-the-art nutrition for plants in all types of hydroponic systems

IONIC for Hydroponics

  • IONIC Hydro nutrients are formulated specifically for hydroponic cultivation. This product is complete in every elemental detail and balanced for precise delivery of nutrients to the plant.
  • IONIC Hydro nutrients are available in standard and hard water options – in either case precisely tailored to the water supply.
  • IONIC Hydro nutrients are available in Grow and Bloom options. These variations are based upon the nutritional requirements of green plants at each stage of the growth cycle. The Grow formulation is designed to maximise potential for vigorous vegetative growth, while the Bloom nutrient is loaded with the crucial elements that support heavy flowering.
  • IONIC Hydro nutrients have a highly stable pH due to unique reactive buffering incorporated into the manufacturing process. This reduces fluctuations in the tank and cuts down the workload for the grower.

Hard Water

Growers in hard water areas should use the special IONIC HW formulation. The Hard Water product has a distinctive HW label on the bottle. Both types of IONIC are available in Grow and Bloom formulations.

IONIC Hard Water solution is more acidic. This is achieved by careful selection of the component mineral salts. A more acidic solution will neutralise bicarbonates on its own. This will reduce the amount of acid needed to control the pH and thus reduce the chance of phosphate accumulation. IONIC Hard Water solution is also specially formulated to take account of the minerals, such as calcium, that are usually present in hard water. By lowering these elements in the nutrient solution it is possible to ensure that the final solution is as close as possible to ideal levels of the major elements. This will reduce the problems associated with hard water and allow the grower to maintain the tank for longer periods between changes.

Are single pack nutrients better than two part nutrients?

Firstly, you only have to purchase one high quality product that is great value for money. The macro elements are locked together in large molecules in exactly the right ratio for plant growth. This technology makes the single pack possible and it also ensures that the target NPK ratio is exactly right to the point that the plants take it up. This process provides a more precise formulation then what was achieved with the old twin packs.

We have been formulating and manufacturing twin packs since 1984 and Optimum and Europonic are still very popular. There is nothing wrong with these products, but IONIC® technology is undoubtedly superior. The large molecule concept allows delivery of specific cations – Calcium – Magnesium and so on, without the usual huge and unnecessary level of anions. This means that a greater percentage of the mineral ions are useful to the plant and that the tank will be stable and balanced for much longer.

People sometimes call IONIC® a beginner’s nutrient –  why is that?

Presumably because it is so easy to use. There is only one bottle to worry about and no hassles with pH – basically fool-proof, which means great results for first time growers. However it is important to remember that IONIC® is a professional formulation from a commercial-oriented company. Once is it diluted and in the tank it is 100% complete. There are no shortcuts or compromises in this solution and it is equal to, or better, than anything else on the market. It is great for beginners but many experienced growers around the world use it for great results as well.

Why is the pH so stable in IONIC®?

This is a result of the manufacturing process, unique to IONIC®, which creates large molecules containing the key macro elements.  The elements are partially buffered and so become much less reactive in terms of pH. For many people the pH stability is the chief advantage that IONIC® offers but even so, it wouldn’t be used if yield or quality were compromised.

Why do you need IONIC® PK Boost in the flowering stage?

Mainly because of the incredible potential of flowering crops to uptake certain minerals from the tank. IONIC® Bloom is precisely formulated to provide the right balance of nutrients to support intense flowering and will give excellent results on its own. However flowering crops have a high demand for specific elements, potassium for example, and a vigorous crop can reduce element amounts in the tank very quickly. Even if the conductivity is being properly maintained with stock solution, the level of potassium in the tank can decline very fast. PK BOOST is an easy way to maintain an ideal level of the specific nutrients that plants need to produce heavy crops. A lot does seem to depend on the size of the tank. If it is small with respect to the number and size of plants involved then the need for Boost is greater. In almost all situations the regular application of PK Boost will enhance flowering and increase yields.

Is IONIC® PK BOOST designed to work specifically with IONIC® BLOOM nutrients?

It is certainly designed to work well with any of the IONIC® BLOOM formulations, but it will also be a superb addition to Optimum Bloom/GreenHaze Bloom, or any good Bloom nutrient. Just follow the instructions or the IONIC® Schedule to get the best results.
