Ona Liquid Odour Neutraliser for Grow Rooms

Neutralise grow room odour instead of covering it up

Ona Liquid is the concentrated form of Ona's industrial-strength odour control formula, built on plant-derived essential oils rather than heavy perfume. Most air fresheners lay a scent over the top of the problem; Ona's neutralising agents bind to odour molecules and destroy them, which is why the brand is the reference point for odour control in small to medium grow rooms. Dilute it for a sprayer or feed it into an Ona dispersal unit for continuous cover. It is non-toxic, eco-friendly and available in Fresh Linen, Pro, Polar Crystal, Tropics, Apple Crumble and Fruit Fusion.

Key Benefits

• Destroys rather than masks - the agents react with airborne odour compounds instead of hiding them.
• Plant-based formula - essential oils, non-toxic and a sound alternative to chemical fresheners.
• Covers small to medium rooms - spreads on normal air movement to treat the whole space.
• Six scents - from the near-neutral Pro through to Apple Crumble and Fruit Fusion.

When Odour Escapes the Tent

Carbon filters handle extracted air, but odour still leaks from door zips, passive intakes and every inspection, and no amount of extra airflow fully fixes that. Ona works on the air in the room the smell escapes into, neutralising it at the point it becomes a problem. Used alongside a filter it closes the gap that ducting alone leaves open.

How to Use

• Dispersal unit: fill a compatible Ona unit and let it release the neutralising agents continuously.
• Spray application: dilute in water in a hand sprayer and aim a short burst high into the centre of the room.
• Placement: treat the room the tent sits in, near intakes and doorways, not inside the tent or filter.
• Top up: replenish as the scent fades, more often through late flower when odour peaks.
• Handling: keep off plants and away from the reservoir, and store sealed out of direct sunlight.
