Description
Description
Gro A-B est décrit comme un mélange idéal de minéraux et de nutriments de la plus haute qualité, dans le but d'aider les plantes à atteindre une croissance optimale tout en développant leur structure. Il est également présenté comme une formule pratique en 2 parties qui maximise l'absorption des nutriments, ce qui est le plus important pendant la phase de croissance lorsque les plantes développent leurs racines, leurs tiges et leur feuillage. Si vous souhaitez une base de cycle végétatif cohérente du début à la fin, Gro A et B remplit clairement son rôle de base fiable pour la phase de croissance.
Dutch Nutrient Gro A et B est conçu pour réduire la liaison et la solidification, favorisant une meilleure disponibilité des éléments minéraux dans l'ensemble de la formule. Il est également décrit comme réduisant le gaspillage d'éléments minéraux, maintenant le profil nutritif plus utilisable dans un format en deux parties. Pour les cultivateurs qui préfèrent une approche plus simple, l'absence d'additifs ou de colorants permet de se concentrer sur la nutrition des plantes plutôt que sur des charges ou des colorants supplémentaires.
Les faits sont clairs : Gro A est 2-0-2, et Gro B est 0-1-3, ce qui renforce son rôle de véritable nutriment de base en deux parties plutôt que de supplément à usage unique. Au-delà des chiffres NPK, la formule inclut explicitement du calcium dans Gro A et du magnésium dans Gro B, favorisant une nutrition équilibrée en phase de croissance sans transformer ce produit en un produit compliqué.
Dutch Nutrient Gro A et B convient aux cultivateurs qui recherchent un nutriment de base hautement concentré en deux parties, conçu pour les semis et les boutures, avec un soutien du cycle végétatif axé sur une croissance maximale et une forte absorption des nutriments.

How to Use Dutch Nutrient Gro B - 1 litre
Step-by-step mixing and feeding instructions for Dutch Nutrient Gro B - 1 litre.
Mixing & preparation
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Dutch Nutrient Gro B - 1 litre 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.
Week-by-week feeding schedule
Vegetative stage — Gro B
- Week 1: mix 1.25 ml per litre of water or nutrient solution.
- Week 2: mix 2.5 ml per litre of water or nutrient solution.
- Week 3: mix 5.0 ml per litre of water or nutrient solution.
Flowering stage — Gro B
- Week 1: mix 5.0 ml per litre of water or nutrient solution.
- Week 2: mix 5.0 ml per litre of water or nutrient solution.
- Week 3: do not use this product during this week of flowering.
- Week 4: do not use this product during this week of flowering.
- Week 5: do not use this product during this week of flowering.
- Week 6: do not use this product during this week of flowering.
- Week 7: do not use this product during this week of flowering.

Tips for best results
- Maintain pH and EC/ppm within the range recommended for your growing medium and crop.
- Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
- Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
- Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
- Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.
Common mistakes to avoid
- Do not mix different nutrients or additives together in concentrated form before adding them to water.
- Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
- Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
- Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
- Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

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.

Frequently Asked Questions
Frequently Asked Questions
What does available phosphate (P₂O₅) do for plant growth?
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Why is soluble potash (K2O) important for plants?
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.
Why is water soluble magnesium important for plant growth?
Water soluble magnesium is important because it quickly restores the plant’s ability to make chlorophyll and produce energy, which helps stop interveinal yellowing on older leaves and improves overall nutrient use; it’s unique because it becomes available immediately in water, making it faster and more predictable than slower magnesium sources.
Why is molybdenum (Mo) important for plant growth?
Molybdenum is important because it helps plants convert nitrogen into usable building blocks for chlorophyll and growth, and it’s unique from many nutrients because it mainly supports enzyme-driven “nutrient use” rather than directly building plant tissue.
Is potassium nitrate better for quick deficiency correction than other potassium sources?
Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.
Is potassium sulfate better than other potassium sources for sensitive plants?
Potassium sulfate is often preferred because it supplies potassium without added chloride and also provides sulfur, which supports protein-building and efficient nutrient use, making it a cleaner, balanced option when plants are sensitive to chloride or when you want potassium without pushing extra nitrogen or phosphorus.
Can phosphoric acid cause nutrient lockout?
Yes, it can if it pushes phosphorus too high or drives pH too low, because both conditions can reduce the plant’s ability to take up key micronutrients and calcium even when they’re present in the feed, which makes phosphoric acid uniquely powerful compared with slower, gentler phosphorus sources.
What does sodium molybdate do for plants?
Sodium molybdate supplies molybdenum, a trace micronutrient that helps plants convert nitrate nitrogen into usable building material, so growth and green color stay steady; it’s unique because it works as a tiny-dose “nitrogen unlocker” rather than a bulk nutrient.
What does magnesium sulfate do for plants?
Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.
