Grotek Monster Bloom™ is a highly concentrated bloom enhancer that supports the flowering and ripening stages for stronger flower development. This classic bloom enhancer is a bloom additive designed to help plants push through the flower phase with the nutrients they demand most.
Monster Bloom™ is positioned for the bud development and blooming stage, when plants shift energy toward building and finishing flowers and fruit. It is known for supporting larger flower clusters while helping improve harvest yield, keeping the focus on bloom performance rather than general-purpose feeding. The formula is built to support the ripening stage, making it a clean fit when the goal is a more complete finish as plants reach peak demand.
This bloom enhancer supports key internal processes tied to flower development. It supports protein and starch synthesis, which matters when plants are building structure and storing energy for rapid development. It also supports stalk and stem strength, helping plants maintain better structure through the flower phase. For overall plant performance, Monster Bloom™ supports the movement of sugars and starches within the plant, helping resources reach developing growth sites more efficiently. It also supports respiration and CO2 uptake, two functions closely linked to how plants convert energy into growth during demanding periods.
Monster Bloom™ is a powder plant nutrient with a 0-50-30 NPK that concentrates its role around bloom-stage phosphorus and potassium support. The input base is derived from monopotassium phosphate, keeping the formulation focused on the core ingredients behind its bloom enhancer profile. The product is also positioned with high solubility and plant availability, supporting a smoother experience in systems where clean dissolving matters. It is further described with benchmark-low impurity levels, which is a meaningful differentiator for growers who prioritize purity in concentrated supplements.
For system suitability, Monster Bloom™ is compatible with hydroponics and soilless (peat/coco) growing setups. It’s a good fit for growers who want a classic bloom enhancer for the flower phase, especially bud development through ripening, with buyer-friendly goals like larger flower clusters, improved harvest yield, and bloom finishing support.
Step-by-step mixing and feeding instructions for Grotek Monster Bloom - 10 KG.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Grotek Monster Bloom - 10 KG well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.
Vegetative stage — Monster Bloom

Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.
Storage and handling
Store this product in its original closed container, in a cool, dry and well-ventilated area. Protect from extreme temperatures and direct sunlight. Keep container tightly sealed when not in use.
Avoid release to drains, natural waterways or outdoor soil. Dispose of unused product and empty containers in accordance with local regulations and the directions on the label.
Important: If medical advice is needed, keep the product label or container available. Always follow the specific instructions and safety recommendations provided by the manufacturer. This safety notice is intended as general guidance and does not replace official label directions or documentation.
| Available Phosphoric Acid (P2O5) | 50.0% |

| Soluble Potash (K2O) | 30.0% |
Available phosphoric acid provides a fast-absorbing form of phosphorus that fuels root growth, energy transfer, and strong flowering. It becomes part of the plant’s total available phosphate supply, but the two terms are not the same—available phosphoric acid is one source of phosphorus, while available phosphate refers to the entire pool of plant-available phosphorus overall.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Monopotassium phosphate provides fast phosphorus and potassium that support energy use, nutrient flow, and bloom development without adding nitrogen, so it helps flowering progress cleanly without pushing extra leafy growth. It’s unique because it delivers a focused PK boost in a highly soluble form, which can correct stage-related demand quickly, but it must be used carefully to avoid potassium-heavy imbalances that can block calcium and magnesium uptake.
