Green House BioBloom 2.5 kg – Bulk Organic Bloom Nutrition for Professional-Scale Flowering
Professional organic growers launching every bloom cycle with BioBloom select the most cost-efficient format available. The Green House Powder Feeding BioBloom 2.5 kg delivers the lowest cost per gram across the entire BioBloom range and treats over 500 liters of substrate per package. A single bag covers a complete bloom season for medium to large installations, including top dressing re-applications for long-flowering varieties.
The Organic Phosphorus Solution at Professional Scale
BioBloom's core innovation – dicalcium phosphate as high-concentration natural phosphorus source – achieves its full significance at professional scale. Delivering 9% P₂O₅ in a certified organic product represents a technical advantage that most organic fertilizers cannot offer. This natural high-concentration phosphorus eliminates the need for supplementary phosphorus additives, simplifying the fertilization program while maximizing bloom production potential. Combined with bone meal as secondary phosphorus source, the dual-release system ensures both immediate and sustained phosphorus availability across the full flowering period. Where single-source organic fertilizers show phosphorus depletion around week 5-6, BioBloom's dual system maintains phosphorus delivery through the critical final ripening weeks when flower density and resin production peak.
- NPK 4-9-9: optimized generative-phase ratio. Reduced nitrogen, elevated phosphorus and potassium for flower and fruit production.
- 18% SO₃: doubled sulfur concentration versus BioGrow for terpene synthesis at peak flowering.
- 8% CaO + 4% MgO: secondary macronutrients for cell structure and chlorophyll production.
- 31% organic matter: feeds the soil food web converting organic nutrients into plant-available forms.
Flexible Dosing Across Genetics
8-week bloom: 3-5 g/L in week 1. Single application.
10-week bloom: 3-5 g/L + top dressing 1-2 g/L in week 3.
12+ week bloom: 3-5 g/L + top dressing 1 g/L in week 5.
The 2.5 kg format supports simultaneous management of multiple genetics with different flowering durations, each following its own dosing schedule. Dry powder stores indefinitely, allowing seasonal surplus to carry forward without quality degradation to subsequent cycles.
Biological Soil Building During Bloom
Unlike mineral bloom nutrition that feeds only the plant, BioBloom simultaneously builds your soil. The 31% organic matter is converted by the microbiome into humus – a stable organic fraction improving water retention, cation exchange capacity, and physical substrate structure. Each bloom cycle with BioBloom leaves a richer, more fertile substrate than it started with. For growers who reuse their soil, this cumulative advantage reduces substrate costs and improves quality with every rotation cycle.

What substrate volume does the 2.5 kg BioBloom cover?
At 3-5 g per liter, 2.5 kg treats 500-830 liters of substrate for the initial application. Including top dressings for long-flowering varieties, this quantity covers multiple complete bloom cycles for installations of 10-30+ plants.
Is BioBloom 2.5 kg suitable for vegetables and fruit crops?
BioBloom suits all plants in the flowering and fruiting phase, including tomatoes, peppers, strawberries, and other fruiting vegetables. The elevated phosphorus and potassium support fruit formation and quality. Adjust dosage based on the specific demands of your crops.
How should the 2.5 kg package be stored after opening?
Store dry, cool, and sealed. Organo-mineral fertilizers may clump when exposed to moisture. Clumping does not affect efficacy but complicates dosing. Always use a dry scoop and reseal immediately after each use.
Is there a formula difference between BioBloom package sizes?
The formula is identical across all formats from 125 grams through 2.5 kg. Only cost per gram varies, decreasing with package size. The 2.5 kg consistently delivers the best value for regular organic bloom cultivation.
