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® Starter Packs

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.

Growth Technology’s 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 their 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.


  • Delivers stunning results
  • Easy to use
  • pH stable

IONIC is the world’s most advanced single part nutrient

The innovation within the product enables the ultimate ease of use for the consumer. The GreenFuse range of stimulants sits alongside the IONIC products and are designed to work together, ensuring the plants can take full advantage of the mineral nutrients in the IONIC formulations.
This easy-to-use combination of products is presented in a convenient starter pack format, with variants of each of the hydroponic growing situations – Hydro, Hydro Hard Water, Coco and Soil.

Each pack comes with 1 litre of Grow, Bloom & PK Boost along with 100 ml sizes of GreenFuse Root, Grow & Bloom. The starters kits are 25% cheaper than buying the products separately.

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 allows us to be far more precise than we can be with the old twin packs.

Well we have been formulating and manufacturing twin packs since 1984 and Optimum and Europonic are still very popular. There is nothing wrong with them – of course – but IONIC® technology is undoubtedly superior. The large molecule concept allows us to deliver specific cations – Calcium – Magnesium and so on, without the huge and unnecessary level of anions that usually goes with them. This means that a greater percentage of the mineral ions are useful to the plant and this means 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. 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 commercially 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. To be sure it is great for beginners but many experienced growers around the world use it for great results.

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.  They are thus partially buffered and become much less reactive in terms of  pH. For many people the pH stability is the chief advantage that IONIC® offers but they wouldn’t use it if they felt that yield or quality were to be 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 the amount of them 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. In our experience a lot depends 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?

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