Description
As the name suggests, Odour Neutralising Agent (ONA) Gel is a great way of combating unwanted smells. Available as either gel or block and in a choice of fragrances, ONA has a wide variety of applications and places where it can be used.
Ona Gel is a low-cost way of managing smells and can also be used by drilling a few holes in the lid to extend its lifespan. Some people have also found that by breaking it out of the pot it is possible to smear it inside ductwork and boost the effects of a carbon filter.
The gel can also be used by placing small amounts in various places to maximise the surface area and avoid the crust that can form at the top of an open jar. It can also be incorporated into ducting by using a T-Piece and, if needed, a ducting reducer (the one litre gels are nearly a perfect fit for a four-inch/100mm reducer).
Estimating the lifespan of the ONAs is hard as much will depend on airflow, humidity, and temperature, but an average would be four to six weeks for the ONA Gel 1L.

How to use
Open the jar and leave it where the smell is. A few ways to get more from it:
- Drill a few holes in the lid instead of taking it off: the gel lasts longer.
- Put small amounts in several places. That gives more surface area and avoids the crust that forms on top of an open jar.
- Fit it into the ducting with a T-piece and, if needed, a ducting reducer.
- Some growers smear a little inside the ductwork to back up a carbon filter.
How long it lasts depends on the airflow, humidity and temperature. For quick touch-ups use ONA Spray; ONA Blocks are the solid version.
Questions
How long does ONA Gel last?
It depends on the airflow, humidity and temperature. Drilling holes in the lid rather than opening the jar makes it last longer.
Can I use ONA Gel in my ducting?
Yes. Fit it into the duct run with a T-piece, and a reducer if needed. Some growers also smear a little inside the ductwork to boost a carbon filter.
