BAC Root Stimulator 60 ml
BAC Root Stimulator 60 ml is an ultra-concentrated biological root stimulator that activates and multiplies beneficial micro-organisms in the substrate for explosive root development. At just 1–2 ml per 10 litres of water, this 60 ml bottle yields up to 600 litres of nutrient solution. The Root Stimulator protects the root environment against soil-borne diseases, cleans drip lines, and creates a pH-lowering effect at the root zone. Apply during the growth phase and through the second week of flowering. Vegan certified and compatible with all substrates. Store cool and do not use enzymes with biological products.
BAC Root Stimulator 60 ml – ultra-concentrated biological root stimulator
Root system quality is the single biggest determinant of plant performance across all substrates and cultivation methods. BAC Root Stimulator is an ultra-concentrated biological stimulator that activates soil micro-organisms to drive rapid root expansion and enhanced nutrient uptake. At just 1 to 2 ml per 10 litres, this compact 60 ml bottle delivers exceptional coverage. Compatible with BAC Soil Grow, BAC Grow Organic, and any other base nutrition across all substrate types.
How BAC Root Stimulator activates soil biology
The Root Stimulator does not act on roots directly but on the micro-organisms present in your substrate. By activating and multiplying beneficial bacteria and mycorrhizae, it creates a root environment where nutrients become available faster and are absorbed more efficiently. The result is a more extensive root network with greater root hair density, increased uptake capacity, and a plant that is structurally stronger and more disease-resistant.
- Microbial activation: stimulates multiplication of beneficial soil bacteria and mycorrhizae that protect and nourish the root zone.
- Disease protection: a healthy root environment provides improved resistance against soil-borne pathogens including pythium and fusarium.
- Drip line cleaning: prevents blockages in drippers and capillaries, keeping automated irrigation systems running cleanly.
- pH-lowering effect: creates a slightly more acidic environment at the root zone, improving trace element availability.
Application window: from seedling to early bloom
Apply 1 to 2 ml per 10 litres of water with every watering. Begin as soon as plants are rooted and continue throughout the vegetative phase and through the second week of flowering. Start at 1 ml per 10 litres for young plants and increase to 2 ml as the canopy develops. Always store the bottle cool and do not combine with enzyme products when using biological cultivation methods. When plants transition fully into bloom, switch to the BAC Bloom Stimulator to maintain optimised microbial activity supporting flower production.
60 ml ultra-concentrate: coverage and value
The extreme concentration of this product means a single 60 ml bottle yields up to 600 litres of nutrient solution at the minimum dosing rate of 1 ml per 10 litres. For growers with a few plants, this comfortably covers an entire vegetative cycle plus the first weeks of flowering. The 60 ml format is ideal for smaller cultivation areas and for growers testing the Root Stimulator for the first time. For higher consumption, the product is also available in 120 ml. Explore the BAC Organic Starterskit to trial the complete BAC biological programme with Root Stimulator included.

What is the dosing rate for BAC Root Stimulator?
Apply 1 to 2 ml per 10 litres of water with every watering. This is an extremely concentrated product — very small amounts are effective. Use throughout the vegetative phase and through the second week of flowering.
When should I stop using BAC Root Stimulator?
Discontinue after the second week of flowering. From that point, the plant's priority shifts from root expansion to flower production. Transition to the BAC Bloom Stimulator which activates micro-organisms that support flowering processes and nutrient transport.
Does BAC Root Stimulator work in hydroponic systems?
The Root Stimulator is compatible with all substrates including soil, coco, and hydro. Its drip line cleaning properties make it particularly valuable in automated irrigation setups. The pH-lowering effect at the root zone is also effective on inert substrates.
Can I use enzymes alongside the Root Stimulator?
BAC advises against using enzymes with biological products. The Root Stimulator works through living micro-organisms, and enzyme products can disrupt this microbial process. Instead, use BAC Final Solution at the end of the grow cycle to break down accumulated waste materials around the roots.
