Description
Grotek Growth Booster is a highly concentrated powdered growth stimulator, designed to boost the vegetative growth of plants from the earliest stages. Thanks to its NPK 16-40-0 formula, it provides a powerful dose of phosphorus and nitrogen that stimulates the formation of strong roots, robust stems, and large leaves.
Its action is based on supplying an immediate energy boost that accelerates plant metabolism, maximizing nutrient absorption capacity and promoting balanced development. Ideal for cannabis crops and other demanding species, Growth Booster offers visible results with a single application, helping plants reach their maximum potential.
Thanks to its balanced and fast-absorbing formula, Growth Booster offers multiple benefits that optimize crop development:
The composition of Growth Booster is based on a concentrated mineral formula with an NPK ratio of 16-40-0, making it an ideal fertilizer for the growth phase. Phosphorus (P) contributes to root development, while nitrogen (N) promotes abundant foliage and intense greenness.
| Element | Percentage | Main Function |
| Nitrogen (N) | 16% | Stimulates leaf and stem growth. |
| Phosphorus (P) | 40% | Promotes root development and subsequent flowering. |
| Potassium (K) | 0% | Not included to maintain balance during growth. |
For application, simply dissolve 1 g of Grotek Growth Booster per 10 liters of water and apply it only once during the growth phase, preferably when the plants have already developed their first true leaves. It is compatible with soil, coco, or hydroponic systems.
It is recommended not to mix Grotek Growth Booster with other fertilizers or stimulators during the same application. Keep the product in a cool, dry place, away from heat sources, and use gloves to avoid direct contact with skin or eyes. Additionally, it must be kept out of reach of children and pets.
