About ONA

How ONA works

ONA's blend of essential oils binds with odour molecules in the air and cancels them. A tub of gel works passively for weeks; a block does the same in a smaller space; the spray is for an instant fix. None of it should go inside the grow room itself, where the same chemistry would reach the plants.

Where to use it

By the exhaust outlet, in the hallway, in the car. A carbon filter deals with the room; ONA deals with what escapes.
