BAC Bloom Organic 1 l
BAC Bloom Organic 1 litre is the full-size format of BAC's certified organic bloom nutrient, designed for growers with larger cultivation areas or multiple flowering cycles per season. Featuring the same Soil Association approved NPK 5-2-5 formulation as the 500 ml variant, this organic base nutrient delivers elevated potassium and phosphorus through biological conversion for superior flower quality, flavour, and aroma. Contains Yuccah wetting agent and high sugar content that actively feeds beneficial soil biology. Dosing at 20–30 ml per 10 litres with every watering. Vegan certified and Ecocert compatible. The cost-effective format for committed organic bloom cultivation.
BAC Bloom Organic 1 litre – scaling certified organic bloom nutrition
For growers who have validated the BAC organic bloom programme and are ready to scale, the 1 litre format delivers the same Soil Association approved NPK 5-2-5 formulation in a more cost-effective package. This organic bloom nutrition follows directly from BAC Grow Organic 1 litre in the BAC biological programme, providing all the nutritional support your plants need for abundant, high-quality flowering through biological soil processes.
Expected outcomes with organic bloom nutrition
Organic bloom nutrition delivers qualitatively distinct results compared to mineral feeding. The organic ingredients are converted by soil micro-organisms into plant-available forms, a process that simultaneously generates oxygen and protective compounds. Plants fed organically develop enhanced resistance to soil pathogens including pythium and fusarium, as well as pest species such as thrips and spider mites. Flower set and final flower formation are more abundant when soil biology is functioning optimally, and the aromatic profile of the harvested product is consistently richer and more complex.
- NPK 5-2-5: bloom-optimised organic profile with elevated potassium for robust flower formation and enhanced sugar production.
- Enhanced flavour and aroma: high sugar content feeds micro-organisms that contribute to a more complex aromatic profile in the final product.
- Improved resilience: biologically active soil provides natural protection against soil-borne pathogens and reduces pest susceptibility.
- Triple certification: Soil Association approved, Ecocert compatible, and Vegan certified.
The complete BAC organic bloom stack
BAC Bloom Organic 1 litre serves as the base nutrition in a comprehensive organic bloom programme. Add BAC Bloom Stimulator from the start of flowering to multiply beneficial micro-organisms and accelerate flower initiation. From week two, introduce the BAC Organic PK Booster 1 litre for natural phosphorus and potassium supplementation that drives in-plant sugar production and intensifies flower maturation. In the final week, BAC Final Solution provides a complete substrate flush for optimal end-product purity and clean flavour.
Scaling up: when 1 litre makes sense
The 500 ml format is the ideal entry point for growers discovering organic bloom nutrition. Once results are validated and the product is confirmed as part of your standard programme, the 1 litre format delivers better value per millilitre and prevents supply interruption during the critical bloom phase. At average dosing of 25 ml per 10 litres, one litre yields approximately 400 litres of nutrient solution. For growers managing multiple plants or larger cultivation areas, this format eliminates the risk of running out precisely when nutritional demand peaks. The entire BAC organic programme scales consistently, maintaining full Soil Association and Ecocert compliance at any cultivation size.

What is the difference between BAC Bloom Organic 500 ml and 1 litre?
The formulation is identical: same NPK 5-2-5, same Soil Association approved ingredients, same dosing at 20 to 30 ml per 10 litres. Only the packaging size differs. The 1 litre format provides better value per millilitre and is designed for growers with larger cultivation areas or multiple flowering cycles.
How many litres of nutrient solution does one bottle produce?
At average dosing of 25 ml per 10 litres, one 1-litre bottle produces approximately 400 litres of nutrient solution. Actual consumption depends on your cultivation area, plant count, and the duration of your flowering phase.
Should I combine BAC Bloom Organic with the Organic PK Booster?
The Organic PK Booster is specifically formulated as the biological complement to BAC Bloom Organic. Introduce it from the second week of flowering for natural phosphorus and potassium supplementation. The combination drives in-plant sugar production and contributes to heavier, denser flowers with improved quality.
Is BAC Bloom Organic suitable for coco cultivation?
BAC Bloom Organic works on both soil and coco substrates. On coco, native microbial populations are lower, making the addition of BAC Bloom Stimulator particularly important. Without active soil biology, organic nutrients cannot be fully converted to plant-available forms, limiting the product's effectiveness.
