Description
Give your plants a living, thriving root environment with Bactivator 250 ml, a powerful, natural bio-inoculant formulated to build a healthy root zone, boost nutrient uptake and enhance overall plant vigour.
Suitable for hydroponics, coco, soil and mixed-media grows, Bactivator helps unlock stronger growth, increased yield potential and improved root health from vegetative stage through flowering.
read the full product overview here...
Bactivator is a two-part biological root inoculant, combining a highly concentrated blend of beneficial microbes and fungi (spores) with a liquid catalyst containing plant-friendly hormones, enzymes and bio-stimulants. Once activated, these microbes colonise the root zone and work symbiotically with your plants, converting waste into bioavailable nutrients, improving oxygen uptake and establishing a robust microbial ecosystem similar to living soil.
Whether you’re growing in hydroponic reservoirs, coco coir, rockwool or traditional soil, Bactivator supports root health, natural immunity and optimal nutrient assimilation for stronger, more resilient plants.
Key Features & Benefits
- Boosts Nutrient & Oxygen Uptake: Beneficial microbes and fungi recycle root-zone waste into bioavailable nutrients while improving oxygen assimilation
- Supports Strong, Healthy Root Systems: Establishes a biologically active rhizosphere for efficient water and nutrient absorption
- Enhances Growth, Flower & Fruit Potential: A healthier root environment promotes vigorous vegetative growth and improved yield potential
- Natural Defence Against Root Diseases & Stress: Microbial populations help suppress harmful pathogens and reduce root-zone issues
- 100% Organic & PGR-Free: Contains only naturally derived microbes, humic and fulvic acids and bio-stimulants
- Compatible with All Grow Media & Systems: Works effectively in soil, coco, hydroponics, rockwool and recirculating setups
How to Use
- Activation: Dissolve one tablet or pellet in approximately 500 ml of lukewarm water
- Catalyst Addition: Add 10 ml of liquid catalyst for every tablet used and stir gently until fully mixed
- Application Rate: Each activated dose treats up to 50 litres of nutrient solution or irrigation water
- Frequency: Apply weekly or with every nutrient or reservoir change
- Usage Window: Suitable for use throughout the entire growth cycle, from seedlings and clones through to flowering and fruiting
- Important Precautions: Do not use alongside hydrogen peroxide (H₂O₂) or other strong oxidising agents
- Optimal Root-Zone Temperature: 17–19 °C, with effective performance maintained up to approximately 30 °C
Frequently Asked Questions (FAQ)
Is Bactivator a nutrient feed?No, Bactivator is a biological additive rather than a nutrient. It enhances the root environment so plants can absorb nutrients more efficiently.
Can Bactivator be used in soil, coco and hydroponics?
Yes, it is compatible with all grow media and systems, including soil, coco coir, rockwool, hydroponic reservoirs and recirculating systems.
How often should Bactivator be applied?
For best results, apply weekly or with each nutrient or reservoir change. Many growers use it continuously throughout the full grow cycle.
Is there a risk of overdosing?
According to the manufacturer, overdosing will not harm plants, although higher doses are generally unnecessary.
Will Bactivator replace base nutrients or fertilisers?
No. Bactivator complements your existing nutrient program by improving root-zone health and nutrient uptake. Base nutrients should still be applied as normal.
If you want to give your crop a strong, living foundation with a biologically active root zone that supports nutrient uptake, oxygenation and natural disease resistance, Bactivator 250 ml offers a simple, organic and highly effective solution for healthier, more productive plants.
