Les nutriments FloraFlex B1 et B2 sont un engrais de base en deux parties pour la floraison. Il s'agit d'un engrais en poudre soluble dans l'eau, conçu pour apporter aux plantes des éléments nutritifs essentiels pendant la floraison. Ce système d'engrais pour cycle de floraison est idéal pour les cultivateurs qui recherchent une fertilisation propre et constante pendant cette phase, sans avoir à stocker une multitude de flacons.
FloraFlex décrit cette gamme comme une formule en poudre en deux parties, facile à utiliser, conçue pour fournir des nutriments purs et à pH stable. Au lieu de dissimuler sa composition derrière un marketing vague, elle mise sur une approche de décomposition élémentaire et les éléments essentiels dont les plantes ont besoin tout au long de leur cycle de floraison. La composition est simple : la vitamine B1 est composée de 14-0-22 et la vitamine B2 de 0-28-18, la première partie apportant l’azote et la seconde, le phosphore et le potassium, plus importants pour la floraison.
Puisque FloraFlex axe sa gamme de nutriments sur les éléments essentiels, les vitamines B1 et B2 sont conçues pour couvrir les besoins nutritionnels fondamentaux, et non pour procurer un simple « coup de pouce ». L'ensemble de la gamme contient des macronutriments, ainsi que des nutriments secondaires et des micronutriments qui contribuent au bon fonctionnement de la plante. Concrètement, cela inclut l'azote, le phosphore et le potassium, ainsi que le calcium, le magnésium, le soufre et des micronutriments tels que le fer, le manganèse, le zinc, le bore, le cuivre et le molybdène.
L'effet de ces éléments sur la plante est tout aussi clair lorsqu'on les considère au niveau fonctionnel. L'azote favorise une croissance vigoureuse et une photosynthèse efficace, contribuant ainsi au maintien d'une couleur foliaire saine. Le phosphore joue un rôle clé dans la photosynthèse et, pendant la floraison, il soutient le développement et la maturation des fleurs. Le potassium contribue à la santé générale de la plante et à la qualité des fleurs et des fruits, tandis que le calcium renforce la plante lors de l'accélération de sa croissance pendant la floraison.
Ce système nutritif en deux parties est conçu pour la culture hydroponique, mais convient également à la culture en terre et hors-sol, ce qui lui confère une grande polyvalence sans altérer sa formule de base. Il est aussi recommandé pour les systèmes de dosage et de fertirrigation, où une poudre soluble dans l'eau et des nutriments à pH stable sont essentiels pour une fertilisation constante. Les nutriments FloraFlex B1 et B2 sont parfaitement adaptés aux cultivateurs recherchant un engrais de base en deux parties pour la floraison, contenant des éléments essentiels, une composition élémentaire ciblée et une base simple et efficace pour cette phase.
Step-by-step mixing and feeding instructions for FloraFlex Nutrients B1 - 25 lb.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of FloraFlex Nutrients B1 - 25 lb 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 — B1
Flowering stage — B1
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.

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.

| Total Nitrogen (N) | 14.0% |
|---|---|
| Nitrate Nitrogen (N) | 13.5% |
| Ammoniacal Nitrogen (N) | 0.5% |
| Soluble Potash (K2O) | 22.0% |
| Calcium (Ca) | 7.0% |
| Molybdenum (Mo) | 0.001% |
Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.
Even in tiny amounts, molybdenum is crucial because it helps plants convert absorbed nitrogen, especially nitrate, into forms they can actually use to build new growth. That makes ammonium molybdate unique from many other micronutrient sources: it supports nitrogen-use efficiency, so a shortage can make plants look nitrogen-deficient even when feeding is adequate, leading to slow growth, pale leaves, and weak vigor unless the bottleneck is fixed.
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.
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.
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.
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.
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.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
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.
