Ona Block Pro 170 g
ONA Block Pro 170 g is the near-odorless variant in the ONA range, engineered for professionals and serious cultivators. While other ONA Block scents leave a light aroma after neutralization, the Pro formula leaves only clean air — comparable to the freshness after a summer rain. The top choice for growers who need to prevent any aromatic transfer to their plants. Also suited for offices, server rooms and storage facilities. Same proven formula of 32 essential oils in a low-scent composition. One 170-gram block provides up to four weeks of coverage. Fully non-toxic and environmentally safe.
ONA Block Pro 170 g — zero-scent odor neutralization for serious growers and professionals
The ONA Block Pro represents the most refined formulation in the ONA lineup. It deploys the same 32 essential oils as every ONA product, but in a composition specifically balanced to leave virtually no residual scent after neutralization. The end result: odors are eliminated and the air simply smells clean — nothing more, nothing less.
Engineered for terpene-conscious cultivators
Advanced growers know that aromatic compounds in the grow environment can interact with plant terpene profiles. The ONA Block Pro eliminates this concern. Deploy the block outside your grow tent, adjacent to your ventilation system exhaust, and let it handle breakthrough odors without introducing competing aromatics. Of all ONA variants, the Pro has the lowest olfactory signature, making it the safest choice for quality-focused cultivation.
Professional and commercial deployment
The near-odorless characteristic makes the ONA Block Pro uniquely suited for professional environments:
- Offices and server rooms: neutralizes electronic equipment and heated plastic odors without affecting the work environment.
- Warehouses and storage units: eliminates musty and mildew odors in confined spaces with limited ventilation infrastructure.
One 170-gram block delivers up to four weeks of performance. Regulate output by drilling holes in the lid for slower evaporation. Completely non-toxic and safe for occupied spaces.

What makes ONA Block Pro different from the scented versions?
ONA Block Pro uses the same 32 essential oils as all ONA variants but in a formulation that produces virtually no detectable fragrance after neutralization. Fresh Linen, Polar Crystal and Apple Crumble each leave a mild pleasant aroma, while Pro leaves only clean, neutral air. Neutralization capacity is identical across all variants — the difference is purely in residual scent.
Will ONA Block Pro affect my plant terpene profiles?
When used correctly, the risk is negligible. Always position the ONA Block Pro outside the grow tent or cultivation chamber — never directly among your plants. Placed in the adjacent room or corridor, the block neutralizes escaping odors without introducing aromatic compounds into the grow environment. The Pro variant carries the lowest scent signature in the entire ONA range, making it the optimal choice for terpene preservation.
