ONA Gel 732g – Odour Neutraliser for Grow Rooms

Industrial-Strength Odour Neutralising, By The Scent

ONA Gel is the odour neutraliser the hydroponics industry has used since 1995 — a blend of naturally derived essential oils that reacts with airborne odour molecules rather than covering them with fragrance. The 732g tub sits between our smaller 426g jar and the 3.8kg pail, giving enough capacity for a grow tent, a drying room or a small commercial space without committing to a bulk size.

Key Benefits

• Neutralises at the source — the gel reacts with odour compounds instead of masking them with scent
• 32 naturally derived essential oils in a proven, industry-standard formula
• Lasts 30–90 days depending on airflow and room temperature
• Safe around people, pets and plants, with no wiring or power required
• A choice of scents so you can match the room, not just mask it

Covering The Gap Between A Small Jar And A Bulk Pail

A small jar runs out fast in anything bigger than a single tent, while a 20kg pail is more capacity than a single room needs. The 732g tub is sized for a tent, a small drying room or an office, giving weeks of coverage without the up-front cost or the storage footprint of the largest sizes.

How to Use

Peel back the foil seal and leave the tub open in the area you want to treat, positioning it where air naturally moves past it — near an intake, a doorway or a fan. Increase airflow across the surface to speed up coverage in a larger space, and reseal the lid when not in active use to extend the life of the gel.
