Plant Nutrient Supplements

Nutrients supplements are essential products to boost healthy plant growth at different stages of a plants life. To be used alongside a usual nutrient programme.


IONIC® PK BOOST is a nutrient supplement designed to be used during the middle/later stages of the flowering period. PK BOOST allows the grower easy control of the extra phosphorus and potassium that can lead to bumper yields. PK BOOST is an ideal addition to IONIC® BLOOM or OptimumBloom/Green Haze Bloom, but it can also be used very effectively with any good quality nutrient solution of the BLOOM variety.

IONIC® PK BOOST is specially formulated to deliver the key elements phosphorus (P) and potassium (K) in a pure form that is instantly accessible to the plant. These crucial ingredients are used in abundance by plants in the flowering cycle and the extra levels provided by PK BOOST can lead to larger flowers and much heavier crops.

IONIC® PK BOOST was also designed to top-up levels of minerals that are usually in short supply in hydroponic tanks. After analysis of hundreds of nutrient samples Growth Technology has developed a very clear understanding of what plants take up, especially during the flowering cycle. IONIC® PK BOOST will replenish the missing elements and restore an ideal tank balance for optimum plant performance.


  • Fully formulated solution – based on research and analysis
  • Contains full profile of crucial elements needed for heavy flowering
  • Crucial element ratio of 14:15
  • Highly concentrated – just 1ml per litre in the tank
  • Easy to use – a simple weekly dose for truly enhanced flower production


 If a nutrient solution is properly formulated, why is there a need to add BOOST?
A well-formulated BLOOM nutrient will give excellent results and for many people that is enough. However crops nearing harvest have a high demand for certain crucial elements, potassium in particular, and a vigorous crop can reduce the amount of available nutrients in the tank very quickly. Even if the conductivity is being properly maintained the level of these crucial elements in the tank can decline very fast. IONIC PK BOOST is an easy way to maintain an ideal level of the specific nutrients that plants need to produce truly heavy crops.
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.

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.
