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 qui reste constante 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 toute la formule. Il est également décrit comme réduisant le gaspillage d'éléments minéraux, gardant le profil nutritif plus utilisable dans un format en deux parties. Pour les cultivateurs qui préfèrent un programme plus simple, le détail "sans additifs ni colorants" aide à maintenir l'accent sur la nutrition des plantes plutôt que sur les charges ou les colorants supplémentaires.
Les faits sont simples : 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 qu'un 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 en faire un produit compliqué.
Dutch Nutrient Gro A et B convient aux cultivateurs qui souhaitent 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.

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Dutch Nutrient Gro A - 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 A
- 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 A
- 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.

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.

Frequently Asked Questions
Frequently Asked Questions
What does nitrate nitrogen (N) do for plants?
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
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 calcium important for plant growth?
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
What is ammoniacal nitrate, and why does it affect plant growth differently than other nitrogen forms?
Ammoniacal nitrate describes nitrogen that behaves partly like ammonium and partly like nitrate, so it can drive fast greening while also shaping root-zone pH and nutrient flow. It’s important because the form, not just the amount, changes how plants build tissue and how easily imbalances like clawing, pH drift, and calcium-uptake issues can appear.
Why do growers use calcium nitrate instead of other calcium sources?
Calcium nitrate is important because it supplies calcium in a fast, highly available form that supports strong new growth and healthy root tips, while also providing nitrate nitrogen for steady, usable growth energy. It’s unique because it delivers calcium together with nitrate nitrogen, making it especially effective during rapid growth phases when plants need both structure-building calcium and immediately available nitrogen at the same time.
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 nitric acid only for pH, or does it feed the plant too?
Nitric acid lowers pH, but it also adds nitrate nitrogen once diluted, so it can influence both nutrient availability and the plant’s growth balance. That makes it important for stable uptake, and unique compared to acids that adjust pH without contributing nitrate.
