Hypochlorous acid irrigation and root-zone maintenance — safe at every growth stage.
Athena Blended Cleanse is a liquid hypochlorous acid (HOCl) solution formulated to descale dripper lines, break down biofilm, and maintain root-zone oxygen levels throughout the entire crop cycle. NPK 0-0-0 and ultra-low TDS mean it runs through your irrigation stack without disturbing EC or mineral balance.
Athena Blended Cleanse is a liquid irrigation and root-zone maintenance product built around hypochlorous acid (HOCl), produced from salt via a proprietary electrochemical process. HOCl is a plant-safe oxidizing agent with no nutritive value — NPK is 0-0-0 — so it contributes virtually no TDS to your solution. The result is a descaling and sanitation tool that integrates into your normal fertigation cadence without requiring a separate flush event or EC adjustment.
Cleanse sits inside the Athena Blended Line alongside Grow A&B, Bloom A&B, PK, CaMg, Balance, and Fade. It appears on the Athena Blended feed schedule as a continuous-use product from propagation through the finish stage, which reflects how it functions: not a one-time corrective intervention, but an ongoing maintenance input that keeps your system clean run after run.
Any licensed indoor or greenhouse cannabis or hemp operation running recirculating hydroponics, RDWC, rockwool, coco, or peat-based media will see consistent returns from a regular Cleanse protocol. Mineral scale and biofilm accumulate gradually in drippers, manifolds, reservoirs, and root zones — often unnoticed until flow rates drop, emitters clog, or plants start showing deficiency symptoms that don't respond to nutrient adjustments. Cleanse is also specifically recommended for use in cloning machines and fresh cutting dips, where its oxidative properties improve cell health and early root development.
For operations running high-frequency fertigation schedules — multiple events per day on coco or rockwool — the risk of mineral precipitation and biofilm formation in emitter heads is elevated. Incorporating Cleanse at maintenance rates in every reservoir fill is a straightforward way to keep fine dripper heads clear and nutrient delivery consistent across the canopy without adding meaningful cost or labor to the protocol.
Descaling and biofilm control: HOCl breaks down mineral scale and organic biofilm that accumulates in lines, manifolds, emitters, and reservoirs. Systems maintained on a regular Cleanse schedule run longer and more efficiently between deep cleans. Elevated Oxidation-Reduction Potential (ORP) in treated water suppresses anaerobic microbial growth and reduces the risk of root pathogens associated with low-oxygen conditions and overwatering.
Non-toxic and non-nutritive: Cleanse is safe on plants at any growth stage. Its neutral pH means it won't destabilize a dialed-in nutrient solution, and its near-zero TDS contribution means it doesn't alter your target EC. The formula is compatible with all common dosing and irrigation hardware, including fine-orifice drippers that would be sensitive to particulate or incompatible chemistry. For final-flush applications, running Cleanse at elevated rates helps strip residual mineral salts from the growing media, which can encourage the plant to fully metabolize stored nutrients in the finishing window.
The 55-gallon drum (SKU: LQB-CL-55G) is the correct format for commercial operations where per-cycle volume makes smaller containers impractical. At a regular-maintenance dose of 2–5 mL per gallon of irrigation water, a 55-gallon drum covers a very large number of reservoir fills before requiring reorder — making this format the standard purchase point for multi-room or multi-tier licensed facilities.
Cleanse integrates cleanly into the full Athena Blended program or can be run alongside the Athena Pro Line since its function is system maintenance rather than nutrition. It is also protocol-compatible with any other nutrient line — operators not running Athena base nutrients can still use Cleanse as a standalone irrigation maintenance product. For multi-site licensed operations standardizing on SOPs, Cleanse's consistent dilution rates (published on the Athena Blended feed schedule) make it easy to train staff and audit dosing across sites.

For routine irrigation maintenance, the published rate is 2–5 mL per gallon of water. For severe reservoir or growing media conditions, increase to 5–10 mL per gallon. For final media and system flush, use 5–10 mL per gallon as well. For cutting dips, Athena recommends 10 mL per gallon. Always refer to the current Athena Blended feed schedule for integration with base nutrients.
Cleanse is designed for continuous use throughout the entire crop cycle, not just end-of-cycle flushes. The Athena Blended feed schedule includes it from propagation through finish. Running it at maintenance rates in every reservoir fill keeps dripper lines clear and root zones aerobic on an ongoing basis, rather than waiting for scale or biofilm to become a visible problem.
No. Cleanse is NPK 0-0-0 with ultra-low TDS. It has a neutral pH and will not meaningfully raise your working EC or destabilize a dialed-in nutrient solution. It is compatible with all dosing and irrigation hardware, including fine-orifice dripper heads.
Yes — recirculating and DWC systems are specifically called out as high-priority use cases. In a recirculating system, mineral complexes with lower solubility ratings can precipitate and lock out nutrients over time. Running Cleanse continuously in a recirculating reservoir suppresses that buildup, keeps ORP elevated, and reduces anaerobic microbial risk in the root zone.
At commercial fertigation volumes — where Cleanse is dosed into every irrigation event across a multi-room facility — the 55-gallon drum significantly reduces per-gallon cost and reorder frequency. For operations running Cleanse as a continuous-maintenance input on the Athena schedule, the 55-gallon format is the practical commercial purchase.
