GreenPlanet Nutrients Massive Bloom Formulation is a premier flowering additive and bloom additive made to support bigger flowers during the flowering stage. This flowering stage liquid fertilizer additive focuses on bloom development and flower size with a compact 1-2-3 NPK that’s easy to recognize at a glance.
Massive Bloom Formulation is described as a comprehensive bloom additive built with the macro and microelements plants need to produce large, healthy flowers. It is formulated with L-form amino acids, a specially formulated vitamin profile, and a unique blend of carbohydrates, giving this flowering additive a broader functional profile than a basic pk-style booster. The chelated mineral profile supports micronutrient availability in a buyer-friendly way, while the formula’s essential nutrients include phosphorus and potassium to match bloom-stage demand.
GreenPlanet also ties Massive Bloom Formulation to several bloom-focused plant benefits that matter late in the cycle. The formula is described as supporting aromatics and essential oils, while also supporting chlorophyll content, photosynthesis, and carbon dioxide utilization as flowers build. It is also positioned to support cell expansion, cell wall thickness, and floral components, which connects directly to the goal of fuller, more developed flowers. For growers who want bloom performance without a long list of separate bottles, those stacked benefits are the core value of this comprehensive bloom additive.
System fit is broad and clearly stated, making it easy to match to your setup. Massive Bloom Formulation is suited for hydroponics, drain-to-waste gardens, recirculating systems, and soil/soilless media. It’s also described as supporting resistance to stressors, helping maintain steady bloom momentum when conditions are less than perfect.
This is a good fit for growers who want a flowering stage bloom additive that’s designed to increase flower size, support aromatics and essential oils, and reinforce bloom-stage performance through a chelated mineral profile, L-form amino acids, and a vitamin profile in one streamlined 1-2-3 formula.

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.
Ammonium phosphate is unique because it delivers phosphorus alongside ammonium nitrogen, which can slightly lower pH right at the root surface and help plants access phosphorus more efficiently. That matters because phosphorus fuels root energy and early establishment, while ammonium supports immediate growth, making this ingredient especially useful for strong starts when used in balanced amounts.
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.
Chelated iron is important because it keeps iron usable for plants even when growing conditions would normally lock iron out, helping prevent the classic yellow-new-leaf symptom caused by low chlorophyll production. It is unique from other iron sources because the chelation protects iron from becoming insoluble, making it a more reliable way to correct iron-related chlorosis when regular iron can fail.
Dipotassium phosphate provides fast, plant-available phosphate and potassium, which supports energy transfer for root and growth processes while improving water control and sugar movement through the plant. It’s important because these two nutrients work together to keep growth steady, but it’s also unique because it can raise root-zone pH compared with similar phosphate sources, so the same dose that helps vigor can also cause micronutrient lockouts if balance and pH stability are ignored.
Molasses is important because it feeds beneficial microbes that support nutrient cycling and root-zone health, which can help plants grow more steadily. It’s unique because it works mainly by energizing the living ecosystem around roots rather than directly supplying plant nutrients like most feed ingredients.
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.
Sucrose matters because it is the plant’s main “transport sugar—” the energy form plants naturally move from leaves to roots, flowers, and fruits, and when added externally it mainly fuels root-zone microbes that influence nutrient cycling and root health. It’s unique because it isn’t a mineral nutrient you “correct” like a deficiency; instead, it can shift the biology and oxygen balance around roots, helping in well-aerated systems but causing problems if conditions are too wet or stagnant.
Total iron (Fe) matters because iron supports chlorophyll development and plant energy systems, keeping new growth green and vigorous; it’s unique from many other nutrients because iron deficiency usually shows up first in young leaves even when older leaves stay green, since iron doesn’t easily move within the plant.
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.
Iron EDTA keeps iron dissolved and available long enough for roots to absorb it, which is why it can quickly improve new growth color when iron is tied up in the root zone. It’s unique because the EDTA chelate balances stability and accessibility, making iron more reliably usable in mildly acidic to near-neutral conditions compared to many non-chelated iron forms.
Monopotassium phosphate provides fast phosphorus and potassium that support energy use, nutrient flow, and bloom development without adding nitrogen, so it helps flowering progress cleanly without pushing extra leafy growth. It’s unique because it delivers a focused PK boost in a highly soluble form, which can correct stage-related demand quickly, but it must be used carefully to avoid potassium-heavy imbalances that can block calcium and magnesium uptake.
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.
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.
Soy protein hydrolysate supplies small peptides and amino acids that can support faster stress recovery and more efficient nutrient use, especially when roots are establishing or plants are under high demand. It is unique because it acts like both a quick organic building-block source and a gentle biological cue, rather than simply adding another mineral nutrient.
