BAC Grow Organic 1 l
BAC Grow Organic 1 litre is the full-size format of BAC's certified organic growth nutrient, designed for growers with larger cultivation areas or multiple cycles per season. Featuring the same Soil Association approved NPK 7-2-3 formulation as the 500 ml variant, this organic base nutrient delivers nitrogen-rich organic feeding with Yuccah wetting agent and a complete trace element profile including calcium, iron, copper, manganese, sulphur, and zinc. Dosing at 10–20 ml per 10 litres with every watering. Vegan certified and Ecocert compatible. The cost-effective choice for committed organic growers scaling their BAC programme.
BAC Grow Organic 1 litre – certified organic growth nutrition at scale
For growers who have already validated the BAC organic programme on a smaller scale, the 1 litre format of BAC Grow Organic delivers the same Soil Association approved NPK 7-2-3 formulation in a more cost-effective package. This organic base nutrient from BAC features Yuccah wetting agent and a comprehensive trace element profile, purpose-built for serious organic cultivation on soil and coco substrates.
When to choose the 1 litre over 500 ml
The 500 ml format is ideal for growers discovering the BAC organic range. Once you have confirmed that the product suits your cultivation style and substrate, the 1 litre format becomes the logical upgrade. It delivers better value per millilitre and ensures uninterrupted nutrition supply throughout the entire vegetative phase. At the recommended dosing range of 10 to 20 ml per 10 litres, one litre covers significantly more growing area and more feeding cycles than the smaller format.
- NPK 7-2-3: nitrogen-dominant organic profile for robust stems, healthy leaf development, and strong plant architecture.
- Yuccah: plant-derived wetting agent ensuring uniform nutrient penetration throughout the root zone volume.
- Trace elements: calcium, copper, iron, manganese, sulphur, and zinc for a complete micronutrient profile without additional supplements.
- Triple certification: Soil Association approved, Ecocert compatible, and Vegan certified.
Building the complete BAC organic programme
BAC Grow Organic 1 litre anchors a comprehensive organic feeding schedule. During the vegetative phase, pair it with BAC Root Stimulator 120 ml to accelerate root development and activate the soil biology that converts organic nutrients into plant-available forms. When plants transition to flowering, switch to BAC Bloom Organic 1 litre and introduce the BAC Organic PK Booster for natural phosphorus and potassium supplementation during peak bloom. The entire programme maintains full organic compliance across all certifications.
Yuccah and soil biology: the hidden performance driver
What distinguishes BAC Grow Organic from many competing organic nutrients is the inclusion of Yuccah, a plant-derived wetting agent. In organic cultivation, physical contact between nutrients and soil micro-organisms is the rate-limiting step in nutrient availability. Yuccah reduces the surface tension of the nutrient solution, enabling deeper and more uniform substrate penetration. This means more beneficial bacteria and mycorrhizae interact with the organic compounds, accelerating the biological conversion to plant-available nutrient forms. The high sugar content in the formulation further feeds this microbial population, creating a self-reinforcing cycle of soil health and nutrient cycling that supports plant development throughout the entire vegetative phase and beyond.

What is the difference between BAC Grow Organic 500 ml and 1 litre?
The formulation is identical: same NPK 7-2-3, same Soil Association approved ingredients, same dosing at 10 to 20 ml per 10 litres. Only the packaging size differs. The 1 litre format provides better value per millilitre and suits growers with larger cultivation areas or multiple growing cycles.
How quickly does BAC Grow Organic produce visible results?
Organic nutrition works through soil biology, which requires several days to a week before nutrients are fully plant-available. Pairing with BAC Root Stimulator accelerates this process by increasing microbial activity in the root zone, shortening the conversion time from organic compounds to plant-available nutrient forms.
Can I use BAC Grow Organic on coco substrate?
BAC Grow Organic works on both soil and coco substrates. On coco, native microbial populations are lower, making it especially important to add BAC Root Stimulator to introduce and activate the micro-organisms responsible for converting organic nutrients into plant-available forms.
Is the 1 litre more cost-effective than buying two 500 ml bottles?
The 1 litre format typically offers better value per millilitre than purchasing two separate 500 ml bottles. For growers who have already confirmed the BAC organic range as their preferred line, the 1 litre is the most cost-efficient choice for regular cultivation.
