FERTox, PATHox, AIRRox -- which one do we need?

CLEANTheory · FERTox, PATHox, AIRRox, product selection, vector matching

The short answer

FERTox™, PATHox™, and AIRRox™ are purpose-built for specific contamination vectors -- they are not interchangeable. FERTox treats water systems. PATHox treats surfaces. AIRRox manages odor and VOC pressure at air handling areas and entry points. Which one you need depends on where your contamination pressure is coming from. Most facilities start with FERTox because the irrigation system is the lifeblood of the grow. Biofilm, pathogens, and reduced water flow are constant headaches that FERTox can begin resolving on Day 1. Some need all three. CLEANTheory's on-site assessment identifies where pressure is highest and prescribes accordingly.

FERTox™ -- the water pathway

FERTox treats the irrigation loop: reservoirs, lines, drip emitters, and root-zone media. It is installed at a single choke point between the reservoir and the manifold -- upstream of everything that reaches a root -- and doses continuously at calibrated concentrations throughout the crop cycle.

FERTox is the right starting point for facilities experiencing:

FERTox is the most immediately demonstrable product in the CLEANTheory program. Biofilm reduction in reservoirs and emitters is visible within the first 30 to 60 days of treatment. Most facilities that start with FERTox see measurable improvement within one grow cycle.

PATHox™ -- the surface pathway

PATHox is an EPA-registered surface sanitizer for high-contact points: benches, tools, shears, trellis clips, harvest trays, door handles, floors. It is set up for push-button dilution and deployed alongside documented SOPs and team training.

PATHox is the right product for facilities experiencing:

PATHox is as much a protocol system as it is a chemistry. The SOPs and training are the part most facilities are missing.

AIRRox™ -- odor and environmental pressure at air handling areas

AIRRox is an automated, timed-release ClO₂ system deployed at entry points and air handling surfaces. It runs on its own schedule, operates within OSHA, NIOSH, and EPA safety thresholds, and reduces odor and VOC pressure without masking agents or operational downtime. Terpene and chemical profiles are unaffected.

AIRRox is the right product for facilities experiencing:

AIRRox is typically the third product added to a CLEANTheory program, after water and surface vectors have been addressed, though facilities with specific odor compliance needs may prioritize it earlier.

How to figure out which one you need

Start with the on-site assessment. CLEANTheory walks your facility, reviews your COA history, evaluates your current sanitation program, and scores the facility against all three contamination vectors. The assessment identifies where pressure is highest and where to start.

For a quick frame before the assessment: where is the contamination showing up? Root zone and irrigation issues point to FERTox. Botrytis, surface mold, and cross-contamination between rooms point to PATHox. Odor pressure and VOC accumulation point to AIRRox. Most real-world contamination patterns involve more than one vector, which is why three separate products exist.
