Biotabs Bactrex 250gr
Biotabs Bactrex 250 grams is the professional bulk format of this organic root zone protectant containing 8 bacterial strains, Trichoderma fungi, actinomycetes and humic acid. With 250 grams you produce 250 litres of treatment solution — enough for thousands of cuttings or months of biweekly maintenance on dozens of established plants. The water-soluble powder protects against pythium and other root pathogens, converts organic matter into plant-available nutrients and actively improves substrate structure. The per-gram cost is substantially lower than the 50 gram format. Dissolve in water and apply within 6 hours. Order this bulk format for continuous root zone protection.
Biotabs Bactrex 250 g — professional-scale root zone bioprotection
Effective biological root protection is not a single event but an ongoing programme. Beneficial microbial populations require regular reinforcement to maintain their competitive advantage over pathogens in the rhizosphere. The 250 g format of Biotabs Bactrex makes this systematic approach economically practical, yielding 250 litres of treatment solution at an optimised per-gram cost. For growers who have integrated Bactrex into their standard biweekly protocol within the Biotabs system, this is the volume-optimised format.
The competitive exclusion principle in practice
Bactrex operates on the ecological principle of competitive exclusion. By introducing a dense population of beneficial microorganisms into the rhizosphere, the product saturates available ecological niches, depriving pathogens of the resources and space needed for establishment. Trichoderma fungi simultaneously engage in direct mycoparasitism — actively consuming pathogenic fungi before they can infect root tissue. This dual strategy of territorial saturation and active predation provides more comprehensive and sustainable protection than reactive chemical treatments.
Treatment capacity and operational planning
The 250 g format delivers substantial operational capacity:
- 250 litres of solution at the standard 1 g/L application rate
- 12,500 cuttings treated (at 50 cuttings per litre)
- 6+ months of maintenance for 20 established plants with biweekly application
- Indefinite shelf life when stored dry in original packaging
System-level integration for comprehensive soil biology
Within the Biotabs biological system, Bactrex provides the active defence layer. Startrex establishes the foundational microbial population and soil structure. Mycotrex extends the nutrient absorption network through mycorrhizal colonisation. BioTabs fertiliser tablets supply the organic matter that the entire soil microbiome converts into plant nutrition. Bactrex completes this ecosystem by providing the biological security that protects every component of the underground network from pathogenic disruption.
Store unused product in a cool, dry location. The dry powder maintains full viability indefinitely. Prepared solution must be applied within 6 hours.

How many litres of solution does 250 grams of Bactrex produce?
At the standard rate of 1 gram per litre, 250 grams produces 250 litres of treatment solution. With biweekly application on 20 established plants, this volume covers several months of continuous root zone protection.
How often should Bactrex be applied to established plants?
For established plants, the recommended frequency is once every two weeks using 1 gram of Bactrex dissolved in 1 litre of water per plant. This regular application maintains the beneficial microorganism population and provides continuous protection against root pathogens.
What is the difference between Bactrex and Startrex?
Startrex is a soil conditioner mixed dry into the substrate before potting — it contains probiotic bacteria, fulvic acid and silicon. Bactrex is a root zone protectant dissolved in irrigation water, specifically containing Trichoderma fungi for pathogen suppression and Bacillus bacteria for nutrient mineralisation. The two products serve complementary functions and are designed for combined use.
Is the 250 g Bactrex more cost-effective than the 50 g format?
The per-gram cost of the 250 g format is substantially lower than the 50 g pack. For growers using Bactrex as part of their regular biweekly protocol, this bulk pricing delivers meaningful savings on the cost of biological root protection per cultivation cycle.
