Dutch Nutrient Hydro-Organic Bloom is a Dutch Nutrient one-part hydro-organic nutrient for bloom-stage nutrition, made for complete organic blooming nutrition in hydroponics, soil, and coco. It’s a completely soluble base nutrient that can serve as a stand-alone nutrient when flowers and fruit are the priority.
Built as a one-part hydro-organic nutrient, Hydro-Organic Bloom is formulated to meet the nutritional requirements of blooming plants in soil-less or soil media. The formula is enriched with OMRI certified organics and is positioned as a non-burning recipe, which makes it a practical fit for growers who want bloom support that stays gentle while development keeps moving forward. Because it’s designed as a stand-alone nutrient, it’s well suited to setups that prefer a simpler bloom foundation without juggling multiple bottles.
Hydro-Organic Bloom is made with a concentrated formula of amino acids and vitamins, supported by humates and electrolytes, plus major-minor-micro minerals. Those inputs are included to support the fertility your soil-less medium needs during bloom, helping keep flowering performance steady from early bloom through the finishing stretch. Alongside core bloom-stage nutrition, it’s designed to support nutrient uptake, helping plants make better use of what’s available in the root zone as bloom demand rises.
Finish quality is part of the focus, too. Organic components in Hydro-Organic Bloom are described as supporting a noticeable increase of essential oils and aromas, which helps bring a more complete, more aromatic finish to fruiting and flowering plants. The formula is also described as helping increase beneficial bacteria in the growing medium, supporting a healthier, more active root-zone environment through the bloom cycle.
The facts layer is simple: Dutch Nutrient Hydro-Organic Bloom carries a 2-8-8 nutrient analysis and is presented as complete organic blooming nutrition for hydroponics, soil, and coco. This is a good fit for growers who want a completely soluble base nutrient with bloom-stage nutrition, stand-alone nutrient simplicity, and finish-focused support for essential oils and aromas in soil-less or soil media.
Step-by-step mixing and feeding instructions for Dutch Nutrient Hydro-Organic Bloom - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Dutch Nutrient Hydro-Organic Bloom - 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.
Vegetative stage — Hydro-Organic Bloom
Flowering stage — Hydro-Organic Bloom

| Total Nitrogen (N) | 2.0% |
|---|---|
| Ammoniacal Nitrogen (N) | 0.9% |
| Nitrate Nitrogen (N) | 0.9% |
| Water Soluble Nitrogen (N) | 0.2% |
| Available Phosphate (P2O5) | 8.0% |
| Available Potash (K2O) | 8.0% |
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.
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.
Available Potash (K₂O) supports strong growth by improving water movement, strengthening plant cells, regulating sugar transport, and helping plants handle stress, making it essential for overall plant health and resilience.
Bat guano is different because it can deliver a noticeable nutrient boost while also feeding the soil microbes that release and cycle nutrients around roots, so plants often respond with stronger green growth or heavier flowering faster than with many other natural amendments. It’s important because its concentration means a small dose can shift plant performance quickly, and that same strength is what makes it unique and worth using carefully for targeted results instead of constant feeding.
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.
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.
Water-soluble nitrogen is important because it dissolves in water and becomes available to plants quickly, helping drive fast green growth, strong photosynthesis, and rapid recovery from nitrogen deficiency. It’s unique because it works immediately rather than relying on slow breakdown or conversion, so it delivers faster results—but also requires more careful control to avoid overfeeding, soft growth, or nutrient imbalance.
Kelp extract supports plant growth by acting as a biostimulant that helps roots stay active, improves stress tolerance, and encourages steadier new growth without functioning like a heavy fertilizer. It’s unique because it influences plant processes and recovery more than it supplies major nutrients, so it works best as supportive “management help” rather than a direct N-P-K replacement.
Monoammonium phosphate feeds roots with phosphate for energy transfer and ammonium nitrogen for fast tissue building, which is why it can boost early rooting and growth more quickly than many other phosphorus sources. It’s unique because the ammonium portion can change root-zone pH and nutrient availability, so using it correctly supports roots, but overusing it can trigger imbalances that look like other deficiencies.
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.
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.
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.
Sea bird guano is often better for fast growth because it can release plant-available nutrients quicker than many other organic amendments while still supporting root-zone biology, but that speed is exactly what makes it different and easy to overuse. Used lightly, it can correct mild hunger and energize growth; used too heavily, it can cause dark clawed leaves, tip burn, and nutrient lockouts that slower organics are less likely to trigger.
