BAC Soil Grow 1 l
BAC Soil Grow 1 litre is a highly concentrated 1-component mineral base nutrient engineered for the vegetative growth phase in soil substrates. Manufactured by Dutch specialist BAC (Biological Activated Cocktail), this undiluted formula features an NPK ratio of 7-1-4 and includes premium red chelate iron for superior trace element bioavailability. The single-bottle system eliminates the complexity of A&B dosing while delivering professional-grade nutrition for both container and full-ground cultivation. With a dosing rate of just 25–35 ml per 10 litres of water at EC 1.6, one litre covers multiple growth cycles. Also available in a 5-litre format for larger operations. Explore the BAC difference in your grow.
BAC Soil Grow 1 litre – concentrated 1-component mineral nutrition for vegetative growth
BAC Soil Grow delivers an undiluted 1-component mineral formula featuring premium red chelate iron for superior trace element bioavailability during the vegetative phase. Produced by BAC, a Dutch manufacturer specialising in plant nutrition since 2000, this soil-specific nutrient carries an NPK ratio of 7-1-4 — optimised for robust stem development, dense foliage, and strong root architecture. Unlike the A&B systems required for coco and hydro, BAC engineered its soil line as a single-component solution, leveraging the natural buffering capacity of soil substrates.
What sets BAC Soil Grow apart from standard soil nutrients?
Several key differentiators define BAC Soil Grow within the competitive soil nutrition market. Understanding these differences helps growers make an informed decision when selecting their base nutrient:
- Red chelate iron: while most manufacturers use standard green DTPA iron chelates, BAC exclusively uses red iron chelate across its mineral range. This premium form maintains molecular stability across a wider pH range, resulting in more consistent and reliable micronutrient uptake even when substrate conditions fluctuate.
- Undiluted concentration: BAC products are formulated without any dilution. At a dosing rate of 25–35 ml per 10 litres, a single 1-litre bottle provides substantially more feeds per unit than diluted competitors, making it a cost-effective choice over multiple growth cycles.
- True 1-component system: all macro and micronutrients are combined in a single stable solution, eliminating the risk of incorrect A/B ratios and simplifying the feeding schedule considerably. This is possible because soil substrates offer natural buffering capacity that keeps all elements available to the plant.
Dosing and application protocol
Apply 25 to 35 ml per 10 litres of water during every watering throughout the vegetative period. Target an EC of 1.6 and adjust based on plant response and substrate conditions. BAC recommends using calibrated pH and EC meters for optimal results — precise monitoring ensures your plants receive exactly the right nutrient concentration at every stage. This nutrient is compatible with all soil types including potting mixes, enriched soils, and full ground cultivation setups. For early-stage root development, combining BAC Soil Grow with the BAC Root Stimulator accelerates root mass establishment and improves nutrient uptake efficiency from the very first weeks of growth.
Integrating BAC Soil Grow into a complete feeding programme
BAC Soil Grow covers the full vegetative cycle. When plants transition to flowering, switch to BAC Soil Bloom for a phosphorus and potassium-optimised formula tailored to generative development. During peak bloom, adding the BAC F1 Extreme Booster — a highly concentrated PK booster compatible with all substrates and nutrient brands — can further enhance flower density and yield. The complete BAC mineral feeding schedule is available on the manufacturer's website for growers seeking maximum performance across every growth stage.

What is the recommended dosage for BAC Soil Grow?
The recommended dosage is 25 to 35 ml per 10 litres of water, targeting an EC value of approximately 1.6. This nutrient can be applied with every watering throughout the vegetative growth phase. Always use a calibrated EC meter to fine-tune the concentration based on your specific growing conditions and plant response.
Why does BAC use red chelate iron instead of standard iron chelates?
Red chelate iron maintains its molecular stability across a broader pH range compared to conventional green DTPA chelates. This means plants can absorb iron and associated trace elements more efficiently, even when substrate pH fluctuates. The result is healthier, greener foliage and improved overall plant vitality throughout the growth cycle.
Can I use BAC Soil Grow in coco or hydro systems?
BAC Soil Grow is specifically formulated for soil substrates. For coco and hydroponic systems, BAC offers dedicated A&B nutrient lines — BAC Coco Grow A/B and BAC Hydro Grow A/B — which are engineered for the specific requirements of inert substrates. Using the correct product for your substrate ensures optimal nutrient availability.
Is BAC Soil Grow suitable for organic growing?
BAC Soil Grow is a mineral (synthetic) nutrient, not an organic product. For organic cultivation, BAC offers a separate biological line including BAC Grow Organic, which is formulated with natural ingredients approved by the Soil Association. Both lines are Vegan certified, but they serve different cultivation philosophies.
