🌱 Destroys odors, doesn't mask them
Unlike standard air fresheners, ONA uses an essential oil complex that chemically binds with odor molecules to neutralize them at the source. Perfect for the flowering stage when odors are most intense.
⏱️ Up to 6 weeks autonomy
A single 500 ml jar protects your space throughout an entire flowering cycle. Open it, place it near your grow tent or extraction outlet, and forget about it.
💪 High-concentration PRO formula
Stronger than the Fresh Linen version, the PRO formula is specifically designed for larger spaces and high-odor crops. Developed by ONA since 1992, it's the reference among professional growers.
How long does an ONA Gel PRO 500ml jar last?
Between 4 and 6 weeks depending on temperature, humidity and ventilation. In warm, ventilated areas, expect 4 weeks; in a cool cellar, up to 6 weeks.
Where should I place the ONA Gel PRO jar in my grow room?Place it OUTSIDE your grow chamber, ideally near the extractor outlet or in the adjacent room. ONA must never be in direct contact with your plants as it will also neutralize the flowers' aromas.
💡 BloomLED tip: pair the ONA Gel PRO with an activated carbon filter for total discretion — the filter captures 95% of odors, ONA eliminates the remaining 5%.
