The Hesi Soil fertiliser kit is particularly popular among home gardeners thanks to its easy application. Designed as a starter kit, it contains all of the Hesi products required for successful cultivation in soil or similar growing media.

Like the Hesi Soil fertiliser kit, the Hesi Coco fertiliser kit is particularly popular among home gardeners thanks to its easy application. Designed as a starter kit, it contains all of the Hesi products required for successful cultivation in coco coir.

Enriched fertilisers for cultivating flowering plants in soil. Hesi Bloom Complex contains bloom-active vital substances, which increase the energy in the plant and maintain healthy soil flora.

Plants in the flowering phase have an ever increasing need for phosphor and potassium. With Hesi Phosphor-Plus, the correct amounts of these substances can be added to the irrigation water when they are needed. The manufacturer provides a clear feeding schedule for simple application, or as a starting point for the dosages to be applied.

Hesi Power Zyme keeps the plant growing media clean, in that it causes residual cellulose to be broken down into dextrose. The dextrose serves as a source of nutrition for the roots and soil flora. Ensures an oxygen-rich plant growing medium as it inhibits rotting and improves the biological balance.
This enables the plant to maintain a much more active metabolism, which also has positive effects during all growth phases.

Hesi TNT Complex is a strong fertiliser, which doesn't overwhelm plants, while still stimulating the plant metabolism. 100% organic nitrogen is highly effective with minimal salinity. Ideal for young plants in the vegetative phase. Mother plants that are to be maintained over extended periods also benefit from reduced salt content, because in this way, the growing media stays healthy for longer (less flushing/rinsing necessary).

Plant starter for healthy roots, high resistance, and optimal conditions in the growing medium. Hesi Root Complex improves the fertiliser absorption and activates the soil bacteria. The bacteria aid plant growth in that they break down unusable substances in the growing medium.

Hesi Boost is a new bloom supplement and complements the well-known product range. This fertiliser provides the optimal conditions to get the flower blossom off to a good start. The additional stimulation of the plant means that more side shoots will develop. The reduced spacing of the lateral shoots will make the plant bushier. When the plant is just starting to bloom, it is given a good foundation for lavish fruit formation.

Hesi Coco is a highly-effective bloom booster, which is specially designed to meet the needs of cultivation in coco coir. The use of high-value raw materials means that Hesi Coco is free from fibre and therefore leaves no deposits in the substrate.

The special hydro fertiliser for explosive
flower blossom: Hesi Hydro Bloom.

Hesi Hydro Bloom covers all of a flowering plant?s basic needs in hydroponic setups. Specially designed for use with tap water, you can easily achieve astonishing yields with the Hesi Hydro products.

Hesi Hydro Growth is enriched with vitamins, complex vital substances and important bacterial nutrition. In hydro setups, the bacteria have two important jobs: They quickly build up healthy flora in the substrate, even in hostile growing media (e.g. rockwool), and also provide the plant with valuable plant-active substances, that stimulate the metabolism both directly and indirectly.

SuperVit contains 25 plant-active vital substances, which form a source of power for plants and soil flora. It provides a supplement to the other Hesi products that includes exactly the substances that enable healthy plant metabolism. As such, SuperVit assists the plants in fully utilising the other fertiliser components, and enables overall more vital plants, which are much less susceptible to stress.

HESI PK 13/14 for flowering intensification. 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 period is the culminating point in the life of a 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 last few weeks of flowering.

• Complete fertilizer set for hydro systems
• Effective nutrients for all growth phases
• Vigorous plants, high yields
• attractive price advantage in the set

With this fertilizer complete set you get a real all-round carefree package for indoor grow in hydrosystems. The liquid fertilizers from HESI are scientifically proven and thanks to their easy handling also very suitable for beginners. HESI is one of the most experienced manufacturers of grow fertilizers and is now active worldwide.

The same applies here as before:

In soil, the pH value sinks evenly, as the nutrients are stored there and are constantly released over a certain amount of time. That doesn?t apply to hydro and coco cultures, as these substrates don?t store any nutrients, but rather only serve to anchor the roots. Ideally, the pH value in these systems would be around 6, with a tolerable deviation of maximum 0.2. In hydro and coco systems, it is crucial that the irrigation water has the optimal pH value when the nutrients are provided, in order to enable maximal absorption.
