Hesi Root Complex

Root stimulator for plants

Root Complex plant starter for healthy roots, high resistance and optimal condition in any plant medium. Improves the absorption of food and activates bacteria in the soil. For healthy, green color, thick stems and a vital root system.

Hesi Root Complex is an elixir for clones and young plants, but also for mother plants and plants under stress. Root Complex is a combination of trace elements with vital components (vitamins, amino acids, plant sugars and enzymes) that provides young plants with an optimal start.

In addition, Root Complex ensures a thicker stem and a strong root system. After repotting and other stressful circumstances, Hesi Root Complex improves the overall condition of the plant. Root Complex stimulates a maximum colonization of healthy micro-organisms in the medium. Root Complex is ideal for mother plants and clones. Add some Hesi Root Complex to the mother plant a few days before the clones are cut, this will ensure that the new plants will already have all the required substances for taking root rapidly.


Hesi SuperVit

Stimulator for plants - Number 1 in Europe

SuperVit contains 25 plant-active vital elements that provide a source of strength for the plant in the soil. SuperVit stimulates the production of growth and flowering hormones on plants. The result: vital plants with profuse flower production.

SuperVit is a mix of 15 vitamins and 10 amino acids, that all play a large role in the metabolism of a plant. The vitamins and amino acids (vital substances) of SuperVit are the building blocks of, among other things, plant hormones, enzymes and chlorophyll.

Plants can produce these building blocks themselves from minerals, but with Hesi SuperVit the plants are supplied with the vital substances in a ready-to-use form. This saves time and energy. The energy that this saved is noticeable as an improvement in the growth and flowering and as optimal resistance and health.

The flower production is boosted, the light absorption of the plant is improved, and the metabolism is accelerated. SuperVit activates growth and flowering hormones and is therefore suitable during all periods of the plant's growth cycle.
Plants are healthier if they are taken care of by SuperVit!

The end result-larger yield and stronger flowers!

Hesi Powerzyme

Enzymes for Plants

Hesi Powerzyme is another first class growth promoter from Hesi that ensures optimum root health at all times. It works by breaking down dead root matter in both soil and hydroponic systems that can build up over time and lead to a reduction of the absorption of nutrients. It is especially useful in the early stages to encourage healthy root growth.

What are enzymes? Enzymes are protein molecules, which catalyse the metabolism. For every task there is a special species of enzymes. Enzymes have two vital advantages:

  • They work 100% independently from cells, therefore they are also isolated in an extract.

  • They can repeat their task many times (working some days without stopping) until they are used up.

  • For this reason Hesi PowerZyme must be used regularly, to keep the plant medium in an optimum condition.

Hesi TNT Complex

Fertilizer for plants growth

Hesi TNT Complex is another first class growth promoter from Hesi that ensures optimum root health at all times. It works by breaking down dead root matter in both soil and hydroponic systems that can build up over time and lead to a reduction of the absorption of nutrients. It is especially useful in the early stages to encourage healthy root growth.

Hesi TNT Complex is a very powerful growth supplement, which is easy on the plants. The nitrogen that is used in TNT is 100% organic. Organic nitrogen compounds have no EC value because they are not salts, but they do contain a high percentage of nitrogen. Therefore young plants are loaded with a minimum of salts, which creates ideal growing conditions. So, it appears that TNT Complex has a low EC value, but its degree of effectiveness is very high.

TNT Complex contains all necessary nutrients and has been enriched with many vital components (vitamins, amino acids, plant active sugars) which guarantee successful growth. Plants that are treated with TNT Complex develop a large number of growing points and become strong and powerful with a healthy green colour.



Hesi Coco Complex

Fertilizer for plans

Hesi Coco Complex, complete plant food for growing and flowering plants on coco. NPK-Fertilizer. Healthy growth and profuse flowering.

Hesi Coco Complex is THE supplement for flowering on coco substrates. Just like all the HESI supplements, Hesi Coco has been stabilized thanks to complex-binding substances and it is free of unnecessary ballast. Hesi Coco is not an A & B supplement, the A+B components are united in one bottle. Hesi Coco Complex contains both organic and mineral nitrogen. All trace elements have been stabilized in protecting complexes and have been enriched with vitamins and other vital elements both for the flowering. This way, a perfect balance is created in the system and a fast build up of a healthy micro-flora is achieved. It is possible that the EC of Hesi Coco is somewhat lower than other coco supplements because no salts have been added, since this would only raise the EC and these would be of no nutritional value to the plant (ballast).


Hesi PK 13/14

Phosphorus and potassium for Plants

Hesi PK 13/14 Extra Phosphorus and Potassium for flowering plants on hydro and coco. PK-Fertilizer. Boosts flower formation.

Plants have an increased need for phosphorus as well as potassium in the flowering phase, by applying Hesi PK 13/14 we completely fulfill this need. The flowering phase is the supreme point in the life of the plant. The metabolism is then working at full power and large quantities of enzymes are being produced for flowering. Furthermore, the plant gets bigger and therefore needs more components. The specific substances that are responsible for this are phosphorus (enzymes and hereditary characteristics) and potassium (for the transport within the plant). To ensure that the plant is not unnecessarily loaded with ballast or an excess of salt too early, Hesi PK 13/14 should be used starting from the second half of the flowering phase up to one week before the end of the cycle. The dosage is gradually increased over the final weeks of the flowering phase.


Hesi pH Corrector

PH-corrector for plants

Hesi pH Corrector pH Minus Growth, pH minus Bloom and pH Plus. Corrects the pH value of food solutions for plants on hydro and coco.

Hesi pH Corrector For cultivation with hydro and coco it is necessary that the feeding water is set to a certain pH-value. This pH range is around pH 6 (5.8 - 6.2). But small deviations above or below this value are still acceptable. The reason for this is that the feeding water determines the root environment because the hydroponic mediums are neutral and only give support to the roots, they cannot store the nutrient particles. For soil this is different, since it is able to store the nutrients and distribute them to the plant over several days, during which the pH value in the soil itself decreases. The feeding water for hydro and coco cultivation however actually runs along the roots and must at this point contain all substances in the proper concentration required by the plant. That is also why the pH-value must be optimal at the moment of feeding, in order to be able to absorb all nutrients maximally. If the pH is much lower, the roots could be damaged. If the pH is much higher, the plant can no longer absorb all nutritional components.
