Hesi Pro-Line Bloom 1l
Hesi Pro-Line Bloom Complex is a complete NPK 3-3-4 flowering fertiliser formulated for soil cultivation. The built-in pH corrector automatically adjusts nutrient solution acidity to the optimal uptake range, eliminating the need for manual pH adjustment in most situations. Enriched with amino acids and vitamins that drive metabolic efficiency during the demanding flowering phase. Contains no unnecessary ballast, ensuring full absorption by the plant without substrate salt build-up. Suitable for indoor, garden and terrace flowering plants. Dosage: 50 ml per 10 litres, applied 1 to 2 times weekly. Order at plantandflower.be for fast delivery across Belgium.
Hesi Pro-Line Bloom 1l – Complete NPK 3-3-4 Flowering Fertiliser with pH Correction for Soil
The transition from vegetative growth to flowering triggers a complete metabolic reorganisation. Nutrient demand shifts decisively toward phosphorus and potassium, while the plant redirects energy from structural growth to reproductive development. Hesi Pro-Line Bloom Complex addresses this shift with a purpose-built NPK 3-3-4 formulation that delivers all required macro and micro nutrients alongside amino acids and vitamins for soil-grown flowering plants.
Integrated pH correction for simplified feeding
Nutrient bioavailability is directly governed by solution pH. Bloom Complex incorporates a built-in pH corrector that automatically adjusts the nutrient solution to a slightly acidic value – the range where all macro elements and trace minerals are simultaneously available for root uptake. This eliminates pH adjustment as a separate step in most growing scenarios, reducing both complexity and the risk of dosing errors that can lock out critical nutrients during the flowering phase.
- Zero-ballast formulation: every component is fully plant-available, preventing residual salt accumulation in the root zone.
- Dual nitrogen sources (mineral + organic): provide both immediate and sustained nitrogen availability throughout the flowering period.
- Stabilised trace elements in organic complexes: maintain bioavailability across pH fluctuations inherent to soil environments.
Feed schedule and transition management
Begin transitioning from growth to bloom nutrition when plants show the first flowering signals or when the photoperiod shifts to 12/12. During the first week, blend the previous growth fertiliser with Bloom Complex at a 50/50 ratio, then switch fully to Bloom. Apply 50 ml per 10 litres of irrigation water, 1 to 2 times per week. One litre of concentrate yields a minimum of 200 litres of ready-to-use nutrient solution. For enhanced flowering performance, pair with Hesi Super Vit throughout the entire cycle to maintain elevated plant energy levels and hormone activity.
PK supplementation in late flowering
As flowering progresses into its second half, phosphorus and potassium demand escalates sharply. The plant channels substantial resources into DNA synthesis and reproductive structure formation, processes that are phosphorus-intensive. Hesi Phosphorus Plus is specifically engineered as a PK booster companion to Bloom Complex for soil cultivation. Adding Phosphorus Plus from mid-bloom onwards supplies the concentrated phosphorus and potassium required to sustain peak reproductive output without altering the balanced NPK ratio of the base feed.
Substrate health and root zone management
Bloom Complex's ballast-free composition preserves soil structure and supports the maintenance of active beneficial microflora in the root zone. A healthy rhizosphere directly impacts nutrient cycling efficiency and plant resilience during the metabolically demanding flowering phase. Complement Bloom Complex with Hesi Power Zym to enzymatically break down dead root material into reusable nutrients, preventing anaerobic conditions and maintaining optimal substrate aeration throughout the bloom cycle.

What is the application rate for Hesi Bloom Complex?
Apply 50 ml of Hesi Bloom Complex per 10 litres of water, 1 to 2 times per week during the flowering period. Do not exceed the recommended dose as the zero-ballast formulation ensures complete absorption of all nutrients. One litre of concentrate produces at least 200 litres of nutrient solution.
Does the built-in pH corrector eliminate the need for pH monitoring?
The integrated pH corrector adjusts the nutrient solution toward a slightly acidic value optimal for nutrient uptake. For most standard tap water sources, this provides adequate pH management. However, if your source water has an unusually high or low pH, periodic verification with a pH meter is recommended to confirm the final solution falls within the ideal range for soil cultivation.
What is the difference between Hesi Bloom and Hesi Phosphorus Plus?
Bloom Complex is the complete NPK 3-3-4 base fertiliser providing all nutrients for the flowering phase on soil. Phosphorus Plus is a supplementary PK booster designed to be added alongside Bloom Complex from the second half of flowering, when phosphorus and potassium demand peaks. Both products work as a system – Bloom as the foundation, Phosphorus Plus as targeted reinforcement.
Is Hesi Bloom Complex suitable for hydro or coco growing?
Bloom Complex is formulated specifically for soil cultivation. For hydroponic systems, Hesi offers Hydro Bloom as the flowering nutrient, and for coco substrates, Hesi Coco serves as the dedicated bloom feed. Each substrate type has distinct nutrient buffering and pH characteristics that require specifically tailored formulations for optimal results.
