Not everyone loves the smell of growing plants, especially indoors, under intense growing conditions. ONA (Odor Neutralizing Agent ) gel doesn’t just cover up odors: through the amazing power of diffusion, volatile compounds that make dank aromas are destroyed, or converted to lower levels of a much more acceptable aroma. ONA gel will mellow out the worst, cattiest green aromas to levels that even the most sensitive visitors won’t mind.

Environmentally safe and non-toxic, ONA gel neutralizes a wide spectrum of organic and inorganic odors, effectively, efficiently, and permanently.

ONA Gel is saturated with ONA liquid concentrate; gardeners simply remove the lid from the jar or pail to expose it to the air and remove odors from the source. Choose from Polar Crystal, professional-strength ONA PRO, or Fresh Linen scent.
