High-concentration liquid rhizobacteria that fixes nitrogen and solubilizes phosphate across veg and bloom.
Front Row Ag Triologic is a liquid microbial root inoculant delivering high concentrations of plant growth–promoting rhizobacteria (PGPR) directly to the root zone. Three beneficial bacterial strains work within the substrate to fix nitrogen, cycle phosphorus and potassium into plant-available forms, and facilitate mycorrhizal colonization — weekly, at 1–2 mL per gallon.
Triologic is Front Row Ag's concentrated liquid microbial root inoculant. Its active ingredient package consists of three beneficial rhizobacteria strains — specifically selected for their nitrogen-fixing and phosphate-solubilizing activity. The formula is delivered as an injectable liquid concentrate, making it compatible with both hand-water drench application and reservoir-based fertigation programs.
The product was built by Front Row Ag's founding team — cultivation professionals whose stated goal was a simple, cost-effective additive line with verified agronomic function. Triologic fits that philosophy: one product, one weekly application, with a defined and measurable mechanism of action rather than a broad-spectrum ingredient list.
Plant growth–promoting rhizobacteria (PGPR) colonize the substrate and perform two core functions. First, nitrogen fixation: the bacterial colonies pull atmospheric and substrate nitrogen and convert it into plant-available forms, reducing dependence on fertilizer nitrogen alone. Second, phosphate solubilization: the bacteria break down bound phosphorus compounds in the growing media, freeing P and K into ionic forms the root system can directly absorb.
Beyond direct nutrient cycling, Triologic's rhizobacteria support the formation of mycorrhizal fungal colonies by supplying nutrition to the mycorrhizae protecting the root system. This dual function — feeding the plant and feeding the beneficial fungi around the roots — is why Front Row Ag positions Triologic as a mycorrhizal colonization facilitator, not just a standalone PGPR supplement.
Applying Triologic early in plant development also helps buffer abiotic stress events. The bacterial colonies can reduce the impact of root burn and transplant shock, and the added stress resistance has downstream effects on consistency across a multi-plant commercial run.
Triologic is designed to run continuously from early veg through the end of bloom — one application per week at 1–2 mL per gallon. It is compatible with Front Row Ag's A/B/Bloom base nutrient system and integrates cleanly alongside PhosZyme (Front Row Ag's enzyme biostimulant) and other supplements in the line.
For commercial operators running stock concentrate systems (3-2-2 or 4-3-3 methods), Triologic is applied as a separate hand-water drench or added to the reservoir independently of the stock tanks — it does not mix into concentrated nutrient solutions. At the 2.5-gallon scale, one container covers significant weekly volume: a 100-gallon reservoir at 1 mL/gal requires 100 mL per application, putting 2.5 gallons (approximately 9,463 mL) at roughly 94 reservoir-doses at that rate.
Facilities running coco, rockwool, or other inert media benefit most directly from Triologic's phosphate solubilization in substrate — the bacteria have a defined matrix to colonize and cycle nutrients within. It also works in living soil systems, though amended media programs should verify compatibility with existing biology before integrating.
The 2.5-gallon jug is the practical volume for licensed operators running multi-light or multi-room facilities. The 500 mL size suits small-batch or craft production; the gallon format works for mid-size rooms; the 2.5-gallon SKU (FRTRIO025) is the buy for operations where weekly application across multiple canopy zones would exhaust smaller containers inside a single crop cycle.
Triologic ships from HSC's supply chain as a single-SKU order or alongside other Front Row Ag products. Operators running the full Front Row Ag program — A/B/Bloom base nutrients, PhosZyme, and Triologic — can consolidate procurement through HSC for consistent supply across the line.

Triologic is formulated as a liquid concentrate compatible with reservoir-based application. It is best applied as a root zone drench and should not be pre-mixed into concentrated stock solutions (A/B/Bloom tanks). For fertigation setups, it can be added directly to the diluted feed reservoir at the 1–2 mL/gal rate before injection, or applied as a dedicated weekly drench event separate from base fertigation.
Yes. Triologic is part of the Front Row Ag product ecosystem and is designed to complement the A/B/Bloom base system. Front Row Ag's own feed charts and resources reference Triologic as a weekly supplement running alongside the base nutrient stack through both veg and bloom phases.
At 1 mL per gallon of feed water, one 2.5-gallon (approximately 9,463 mL) container yields roughly 9,463 gallons of treated feed solution. A 100-gallon reservoir treated weekly uses about 100 mL per application — approximately 94 weekly doses from one jug. Actual duration depends on your reservoir volume and how many zones you're treating per week.
Triologic is effective in inert substrates including coco and rockwool, where the rhizobacteria colonize the media and cycle nutrients directly in the root zone. It also works in living soil programs, though operators with heavily amended soils should confirm compatibility with any existing microbial inoculants already present in the substrate.
Front Row Ag recommends applying Triologic early in plant development to establish rhizobacteria colonies before the plant's peak nutrient demand. Early inoculation allows the bacteria to become established in the substrate and begin cycling nitrogen and phosphorus before canopy development accelerates in mid-veg and early flower. Applications continue weekly through the end of bloom.
