Ozona odour control products neutralise grow room and grow tent smells at the molecular level, rather than masking them with fragrance. This Australian-made range covers solid Odour Blocks, Natural Air Freshener sprays, and the electronic Mistral Odour Neutraliser with Vapour Gel — suited to hydroponic setups, drying rooms and any home grower wanting discreet, ongoing odour management.
For natural, non-toxic grow room odour control
Strong-smelling crops are one of the fastest ways to draw unwanted attention to a home grow, and carbon filtration alone doesn't always keep pace with peak flowering odours. Ozona tackles the problem at its source, using natural plant-based agents that react with and neutralise odour molecules rather than covering them up. That means fresher air in your grow tent without a heavy synthetic fragrance lingering over your plants.

How to choose
Passive vs powered odour control
If you're just starting out, an Odour Block or Natural Air Freshener spray is the simplest option — no power source needed, just place it in your tent or grow space. For larger rooms or persistent odours, the Mistral unit runs continuously on 12V DC power, using Vapour Gel to maintain steady odour neutralisation across roughly 3m³ to 10m³.
Choosing a scent
Lavender and vanilla suit a calming, softer background aroma, eucalyptus brings a sharper, fresher note, and talc is closest to a neutral, low-fragrance option for growers who prefer minimal scent.
Blocks vs sprays
Odour Blocks provide slow, continuous release over weeks, while the Natural Air Freshener spray is better for a quick refresh or for targeting a specific area.
All Ozona products are proudly Australian made and owned, tested and stocked by A-Grade Hydroponics' Melbourne-based team. Need help matching odour control to your grow room size? Contact our horticultural support team or browse the full Ozona range.
