Not everyone loves the smell of growing plants, especially indoors, under intense growing conditions. ONA gel is an Odor Neutralizing Agent (see what they did there?) that doesn’t just cover up odors: through the amazing power of terpene diffusion, volatile compounds (that smell) are destroyed, or converted to lower levels of a much more acceptable aroma.

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

Pro-tip: ONA Fresh Linen Gel is a light, clean scent of fresh laundry. If that’s not your style, try Polar Crystal. For a quick blast of spray to rapidly knock out the worst odors instantly, choose ONA Pro Mist.
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.
