Passion and professionalism come together in the nutritious HESI plant nutrients.  Right from the start, high quality has been the most important trademark of Hesi plant nutrients. Valuable additives such as vitamins, amino acids, enzymes and plant sugars turn each product into a source of health and nourishment for plants. The latest developments - the hydro nutrients and the coco nutrients - are full of these nutritious ingredients, and the results are therefore very promising. Special characteristics make the nutrients interactive, whereby it can automatically adjust the pH value of the soil to achieve the desired level of acidity, for example. The high doses of chelates guarantee the constant and optimum availability of all the nutrients. Hesi maximises results and is easy to use. The comprehensive range of Hesi products offers an optimum solution for every cultivation method. Root-Complex and Super-Vit, the ultimate plant conditioners for all growth mediums, have become commercial successes since their introduction, and the soil nutrients with TNT-Complex, Bloom-Complex and Phosphor-plus are the leading products in the HESI range. Hesi Hydro Growth & Hydro Bloom Hesi Hydro supplement is available in a growth and bloom version. Hesi Hydro contains complex-binding substances that keep the trace elements stable and make them tolerant to the nutritional components. Because of this they remain stable until they are absorbed by the plant. Furthermore, the complex-binding substances make the trace elements independent of the pH-value, so that they remain available at every level. Hydro Growth contains proportionally more nitrogen components than Hydro Bloom because in the growth phase the plant uses a lot more nitrogen for the production of new plant parts. The vital components are fully geared to the growth period and this is why the plant is pampered in a hydro medium as well. Hydro Bloom contains a higher concentration of phosphorous and potassium components compared to the Hydro Growth. Plants have an increased need for phosphorous as well as potassium in the flowering phase in order to create strong and healthy flowers. During the first half of the bloom this need is satisfied 100% by Hesi Hydro Bloom. In the second half of the flowering phase, Hesi PK 13/14 is added together with Hydro Bloom in order to fulfil the needs entirely. Hydro Bloom contains a mix of vital substances that are particularly geared to the flowering phase.

Apart from the nutrition (nitrogen, phosphorous, potassium, magnesium, calcium, trace elements, etc) Hesi Bloom Complex has also been enriched with vital components (amino acids and vitamins) that stimulate the development of the plant in an optimal manner. The result of this is an exuberant bloom! In addition, Hesi Bloom Complex contains a pH corrector. The pH level of the feeding water is corrected to a slightly acidic value. The plant can absorb all the administered nutrients optimally around a slightly acidic value. Bloom Complex contains no unnecessary ballast and is therefore fully absorbed by the plant. The trace elements have been stabilized in organic complexes. That is why they remain available and stable at all pH levels even when they are inside the plant. Moreover, Bloom Complex contains two kinds of nitrogen: mineral and organic.

Hesi Phosphorous Plus

Hesi Phosphorous Plus is used in combination with the Hesi Bloom Complex in the second half of the flowering phase. During flowering, the plant develops an increased need for phosphorous and potassium.
Using Phosphorous Plus, we give plants the right means at the right moment: phosphorous for extra formation of flowers and potassium for a fast transport to the flowers.
Hesi Phosphorous Plus has been balanced to the ratios in the soil environment and ensures that the plants are taken care of in an optimal manner.
Thanks to the use of high-quality ingredients, the plants absorb all substances offered to them so that no residues are left behind (no ballast salts).
With Phosphorous Plus the formulation of the flowers is more powerful.

Hesi Coco

Hesi Coco is the supplement for growth and 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 contains both organic and mineral nitrogen. All trace elements have been stabilized in protecting complexes and have been enriched with vitamins and other natural elements both for the growth and flowering periods.
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. It is therefore important that the maximum of 5ml/1 litre is not exceeded.

Hesi PK 13/14

Plants have an increased need for phosphorous as well as potassium in the flowering stage. By applying PK 13/14 we completely fulfil 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 phosphorous (enzymes and hereditary characteristics) and potassium (for the transport within the plant).
To ensure that the plant is not unnecessarily loaded with 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 harvest. The dosage is gradually increased over the final weeks of the flowering phase.

Root Complex

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 re-potting 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.

TNT-Complex

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 the 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.

Super Vit

Super Vit is a highly concentrated mix of vitamins & amino acids that improve the metabolism andoverall health of the plant. This results in stronger growth and a better flowering. It is suitable for all plants and applications.
Super Vit 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 of Super Vit 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 Super Vit the plants are supplied with the vital substances in ready to use form.
This saves time and energy. The energy that is saved is noticeable as an improvement in the growth and flowering and as optimal resistance and health. The flower is boosted, the light absorption of the plant is improved and the metabolism is accelerated.
Super Vit activates growth and flowering hormones and is therefore suitable during all periods of the plant's cycle. Plants are healthier if Super Vit is used: and they produce thicker flowers.
