Green House Powder Feeding Bio Bloom 125 gr
Green House Powder Feeding BioBloom 125 gr is a 100% organic powder fertilizer with NPK 4-9-9, formulated for the flowering and fruiting stage of all plants. This organo-mineral blend delivers high-concentration natural phosphorus via dicalcium phosphate and bone meal, providing complete bloom nutrition over 8 weeks. With 18% SO₃ for terpene biosynthesis and 8% CaO for structural flower integrity. Control Union certified, non-GMO. Available at plantandflower.be with fast Belgian shipping.
Green House Powder Feeding BioBloom 125 gr – Certified Organic High-Phosphorus Bloom Nutrition
Following vigorous vegetative growth with BioGrow, the flowering phase demands a fundamentally different nutritional profile. BioBloom is the bloom component of the Green House Powder Feeding organic line: a finely milled organo-mineral blend with NPK 4-9-9, engineered for maximum flower and fruit production. The central innovation of BioBloom is its ability to deliver phosphorus in high concentration in natural form – a challenge most organic fertilizers fail to meet. The 125 gr format enables initial evaluation of organic bloom performance on your specific setup.
NPK 4-9-9: Bloom-Phase Nutrient Engineering
The 4-9-9 ratio reflects the modified metabolic demands of the generative phase. Phosphorus (9% P₂O₅) drives ATP-mediated energy transfer required for intensive cell division during flower formation. Potassium (9% K₂O) regulates sugar transport to flowers, strengthens cell walls, and controls stomatal function. Nitrogen (4%) is deliberately reduced versus BioGrow – excess nitrogen during bloom delays maturation and promotes unwanted vegetative growth at the expense of flower production.
- 8% CaO: structural integrity of cell walls and fruits. Essential for solid flowers that support their own weight through maturity.
- 4% MgO: central atom in chlorophyll – maintains photosynthetic capacity even as the plant redirects energy toward generative production.
- 18% SO₃: double the BioGrow concentration. Sulfur is a constituent of the enzymes producing terpenes and essential oils – critical for aroma profile and resin production.
Dicalcium Phosphate: Solving the Organic Phosphorus Challenge
The primary limitation of traditional organic fertilizers is their inability to deliver adequate phosphorus in natural form. Green House resolved this through dicalcium phosphate – a natural mineral delivering phosphorus concentrations comparable to synthetic sources while remaining fully compatible with organic certification. Combined with bone meal phosphorus, BioBloom provides a dual phosphorus system: one fraction immediately available, one releasing slowly over 8 weeks. The 31% organic matter feeds the substrate microbiome – bacteria, fungi, and protozoa that convert organic components into plant-available nutrients. Control Union certification (CU 855395) guarantees full organic compliance of all ingredients, with non-GMO sourcing from Germany and Switzerland.
Dosage by Flowering Duration
8 weeks: 3-5 g/L substrate in week 1, single application.
10 weeks: 3-5 g/L in week 1 + top dressing 1-2 g/L in week 3.
12+ weeks: 3-5 g/L in week 1 + top dressing 1 g/L in week 5.
Combine with BioGrow 125 gr for the vegetative phase and BioEnhancer 125 gr as biological activator throughout the cycle.

When should I switch from BioGrow to BioBloom?
Switch to BioBloom at the onset of flowering. Mix into the substrate or apply as top dressing in the first flowering week. The transition is direct – no need to wait for complete BioGrow depletion.
Why does BioBloom contain double the sulfur of BioGrow?
BioBloom contains 18% SO₃ versus 9% in BioGrow. The higher concentration supports terpene and essential oil biosynthesis which peaks during flowering. Sulfur is an essential building block of the enzymes responsible for producing these aromatic compounds.
How much substrate does 125 gr of BioBloom treat?
At 3-5 grams per liter, 125 grams treats approximately 25-40 liters of substrate for the initial application. For varieties with longer flowering periods (10+ weeks), reserve a portion for mid-bloom top dressing.
Is BioBloom compatible with autoflowering varieties?
BioBloom works excellently with autoflowers. For their shorter cycle, adjust dosage to 2-3 grams per liter of substrate. The slow-release formula provides continuous nutrition throughout the entire bloom phase without overfeeding risk.
