Ona Liquid can be diluted in water or connected directly to a sprayer to quickly, and safety, neutralise any unwanted grow room odours.

The molecules that make up Ona Liquid, when dispersed into the air will react with unwanted odour molecules, effectively neutralising them and leaving the surrounding air clean and fresh, with hint of either Fresh Linen or Polar Crystal.

The formula of Ona Liquid is organic, non-toxic, bio-gradable as well as eco-friendly making it safe to use around people, pets and plants, meaning it can be used in and around grow rooms with no adverse effects.

Although Ona Liquid is used by many to rejuvenate Ona Gel, it’s not something that’s recommended due to the different formulas and not being suitable to be used as an evaporator.
