L'extrait d'algues marines House & Garden est un additif conçu pour favoriser un système racinaire plus robuste et une croissance végétative vigoureuse des plantes en pot. Cette solution concentrée d'algues est un complément alimentaire qui apporte les bienfaits naturels des algues marines norvégiennes de manière simple et régulière.
Formulé à base d'algues marines norvégiennes pressées à froid, l'extrait d'Algen favorise la croissance des radicelles et la performance globale de la zone racinaire. En stimulant la formation de radicelles plus fines, il améliore l'absorption des oligo-éléments, permettant ainsi aux plantes de mieux tirer profit des nutriments déjà présents dans votre programme d'engrais. Il en résulte une croissance plus régulière et vigoureuse, notamment lors du développement de la structure et du feuillage.
L'extrait d'algue est fabriqué à partir d'algue noueuse norvégienne (Ascophyllum nodosum) et est produit par extraction à l'eau froide afin de préserver ses composés naturels. Il contient des enzymes actives, de la cytokinine, des acides aminés, ainsi qu'un large éventail de macro et micronutriments. Ces composants issus d'algues sont souvent recherchés comme additifs pour les producteurs qui souhaitent une nutrition plus complète et adaptée à leurs plantes, au-delà des seuls nutriments de base.
Au jardin, les bienfaits se manifestent par une vitalité visible des plantes, bien plus que par des caractéristiques complexes. L'extrait d'algue favorise une croissance végétative vigoureuse, un système racinaire robuste et une meilleure absorption des oligo-éléments grâce à un développement accru des poils absorbants. Il contribue également à préserver la couleur du feuillage, signe concret de la bonne santé des plantes durant leurs périodes de croissance clés.
Pour une utilisation simple et efficace dans les installations modernes, Algen Extract est formulé sans colorants ni régulateurs de croissance synthétiques. Il est également présenté comme parfaitement adapté aux substrats de terre et de coco, ce qui en fait un complément d'algues idéal pour les cultivateurs utilisant ces milieux et recherchant un supplément à base de varech pour la zone racinaire, en phase végétative et en début de floraison.
Ce produit convient parfaitement aux cultivateurs qui recherchent un additif à base d'algues favorisant le développement racinaire, l'absorption efficace des nutriments et une croissance végétative saine en terre ou en fibre de coco, sans transformer la routine en projet scientifique.

| Total Nitrogen (N) | 0.2% |

| Ammoniacal Nitrogen (N) | 0.04% |
| Nitrate Nitrogen (N) | 0.16% |
| Soluble Potash (K2O) | 0.4% |
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.
Ammonium nitrate is unique because it provides nitrogen in two plant-usable forms at once, which can give a fast green-up while still supporting steadier uptake depending on the root-zone conditions. That matters because it can correct true nitrogen shortages quickly, but it also needs careful balance since too much can push overly soft growth and trigger pH drift and nutrient imbalances.
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.
No, potassium hydroxide is mainly a strong pH-raising ingredient that changes how nutrients behave and how roots can access them, and its potassium addition is usually secondary. It’s important because stable pH prevents false deficiency symptoms and uptake stress, and it’s unique from other potassium sources because it’s used for acidity control rather than primarily for plant nutrition.
Seaweed is mainly a plant booster because it supports roots, stress tolerance, and nutrient efficiency more than it supplies full nutrition. It’s unique because ocean-derived compounds help the root zone and plant growth signals in a gentle way, so plants often recover faster and grow more steadily when the basics are already covered.
