BAC Root Stimulator 120 ml
BAC Root Stimulator 120ml delivers a concentrated dose of beneficial micro-organisms that colonise your substrate and drive explosive root development from day one. This enzyme-free biological formula activates soil life to enhance nutrient uptake across all growing media including soil, coco and hydro systems. The 120ml format provides superior value for growers managing multiple plants or running consecutive grow cycles. Certified organic and vegan, it requires just 1 to 2 ml per 10 litres of water for measurable results. Apply from propagation through the first two weeks of flowering.

BAC Root Stimulator 120ml – concentrated biological root activator
Root zone biology determines yield potential long before flowers appear. BAC Root Stimulator 120ml introduces a targeted consortium of live micro-organisms that establish symbiotic relationships with root systems, dramatically increasing nutrient absorption efficiency. Whether paired with BAC Soil Grow or integrated into a third-party feeding schedule, this stimulator provides the biological foundation every successful grow requires.
Micro-organism technology versus enzyme-based products
Most root stimulators on the market rely on enzymes to break down dead organic matter around the root zone. BAC takes a fundamentally different approach. The live micro-organisms in Root Stimulator actively colonise your substrate, forming a biological network that improves phosphorus and potassium availability at the root surface. This living ecosystem persists throughout the grow cycle, continuously supporting nutrient uptake rather than providing a one-time enzymatic reaction. The result is measurably denser root mass with greater branching, translating directly to improved nutrient absorption capacity during the critical flowering phase.
- Certified organic and vegan: free from animal-derived ingredients, suitable for sustainable and certified organic growing operations.
- Undiluted concentrate: at just 1–2 ml per 10 litres, the 120ml bottle delivers exceptional coverage per application with minimal product waste.
- Natural pH reduction: contributes to maintaining optimal pH levels in your nutrient solution, reducing the need for separate pH adjusters.
- Drip system compatible: helps keep irrigation lines and drippers clean through biological activity, reducing mineral buildup and maintenance requirements.
120ml format: built for serious growers
The 120ml bottle is engineered for growers who have already validated BAC Root Stimulator's performance and want to scale efficiently. With BAC's super-concentrated, undiluted formula, the cost per application drops significantly compared to the 60ml entry-size bottle. For multi-plant setups, perpetual harvests, or commercial-scale grows, the 120ml format represents the optimal balance between investment and coverage. As a Dutch company with over two decades of formulation expertise, BAC delivers consistency you can rely on across every bottle and every batch.
Application protocol and transition to bloom
Begin applying BAC Root Stimulator immediately after transplanting clones or seedlings into their final substrate. Add the product to your nutrient solution at each watering and maintain application throughout the vegetative phase and into the first two weeks of flowering, when root development remains critical for supporting bud formation and overall yield potential. The micro-organisms will establish themselves progressively, building a more robust biological network with each application. After week two of bloom, transition to the BAC Bloom Stimulator to shift biological support toward flower development, potassium uptake, and enhanced terpene production. This sequential approach ensures continuous micro-organism activity at every growth stage from seedling to harvest.

How many grow cycles does a 120ml bottle of BAC Root Stimulator cover?
At the recommended dosage of 1 to 2 ml per 10 litres, a 120ml bottle typically covers multiple full grow cycles depending on plant count and watering frequency. Most growers running a standard indoor setup find the 120ml format lasts significantly longer than expected due to the ultra-concentrated formulation.
Can BAC Root Stimulator be used in recirculating hydro systems?
BAC Root Stimulator performs well in recirculating hydroponic setups. The micro-organisms adapt to the hydro environment and provide an additional benefit by helping to keep drip lines and irrigation components clean through their natural biological activity, reducing the risk of mineral salt buildup.
What makes BAC Root Stimulator different from mycorrhizae products?
While mycorrhizae form fungal networks around roots, BAC Root Stimulator uses a proprietary blend of beneficial micro-organisms that activate soil life more broadly. These organisms enhance nutrient availability across the entire substrate rather than relying solely on fungal symbiosis, making them effective in both organic and mineral growing environments.
Is BAC Root Stimulator 120ml compatible with non-BAC nutrient lines?
BAC Root Stimulator is fully compatible with nutrient lines from other manufacturers. The biological micro-organism formula does not interfere with mineral or organic base nutrients. Simply add it to your existing feeding schedule at 1 to 2 ml per 10 litres alongside your regular nutrition.
