Biotabs Bactrex 50gr
Biotabs Bactrex 50 grams is an organic soil fertility improver containing beneficial bacteria and Trichoderma fungi engineered to protect root systems and enrich substrate biology. The water-soluble powder delivers 8 bacterial strains including 6 Bacillus species, actinomycetes and humic acid, encapsulated in Yucca extract for rapid root zone colonisation. Dissolve 1 gram per litre of water to create a treatment solution — 50 grams yields 50 litres. Bactrex shields cuttings and seedlings against pythium and other root pathogens, converts organic matter into plant-available nutrients and improves soil structure. Apply solution within 6 hours of preparation. Explore this certified organic root zone protectant.
Biotabs Bactrex 50 g — organic root zone defence with Trichoderma, Bacillus and actinomycetes
The root zone is the most biologically contested space in any growing system. Pathogenic fungi like pythium and fusarium exploit sterile or weakly colonised substrates, attacking vulnerable roots before the plant can establish natural defences. Biotabs Bactrex pre-empts this threat by flooding the root zone with a carefully engineered consortium of beneficial microorganisms that outcompete pathogens for resources and space. The 50 g format is the entry-level size for growers evaluating the Biotabs biological protection system.
Microbial composition and mechanisms of action
Bactrex delivers a multi-layered defence through the combined action of distinct microbial groups:
- 6 strains of Bacillus spp. — specialised rhizobacteria that decompose organic matter, solubilise phosphorus, potassium and calcium, and produce compounds that directly stimulate root growth
- Trichoderma fungi — mycoparasitic organisms that actively prey on pathogenic soil fungi including pythium and fusarium, consuming them before they can infect root tissue
- Actinomycetes — filamentous microorganisms that break down complex organic compounds and contribute to soil aggregate formation, improving substrate structure
- Humic acid — enhances cation exchange capacity and nutrient retention in the root zone
All components are formulated in soluble Yucca extract with organic catalysts that ensure rapid activation and colonisation upon dissolution in water.
Application protocol
Dissolve 1 gram of Bactrex in 1 litre of water. Stir thoroughly and apply to the root zone. For cuttings and seedlings: one litre of solution treats 50 young plants. For established plants: apply 1 gram per litre every two weeks. Critical: Bactrex is a living product — the solution must be used within 6 hours of preparation.
Pair Bactrex with Startrex for substrate conditioning and Mycotrex for mycorrhizal inoculation. Research demonstrates that the combination of Trichoderma and mycorrhizae amplifies the benefits of each organism through synergistic interactions.
50 grams: concentrated entry format
The 50 g pack produces 50 litres of treatment solution — sufficient for multiple application rounds in a compact grow setup. For larger operations or regular biweekly application schedules, the 250 g bulk format provides five times the product at a lower per-gram cost. Store unused Bactrex powder in a cool, dry location; it remains viable indefinitely when kept away from moisture.

How many litres of solution does 50 grams of Bactrex produce?
At the standard rate of 1 gram per litre of water, 50 grams of Bactrex produces exactly 50 litres of treatment solution. One litre of this solution is sufficient to treat 50 cuttings or seedlings.
How quickly must the Bactrex solution be used after mixing?
Bactrex is a living product — the bacteria and fungi activate immediately upon dissolution in water. The solution must be applied within 6 hours of preparation to ensure maximum effectiveness. Only prepare the amount needed for immediate use.
Does Biotabs Bactrex protect against pythium?
Bactrex contains Trichoderma fungi that actively parasitise pathogenic soil fungi including pythium. For optimal protection, apply Bactrex immediately after sowing or transplanting to allow Trichoderma to colonise the root zone before pathogens can establish.
Can Bactrex be used together with Mycotrex?
Bactrex and Mycotrex are designed for combined use within the Biotabs system. Bactrex provides root zone defence via bacteria and Trichoderma, while Mycotrex introduces mycorrhizal fungi that expand nutrient uptake capacity. Scientific research confirms that the Trichoderma-mycorrhizae combination produces synergistic benefits.
