Ona Natural Odor Neutralizing Gel
Have a question?
Popular, Practical & Powerful. ONA Gel is a best seller with hydroponics and indoor gardeners. It permanently eliminates any airborne odors, cleanly and effectively and is environmentally friendly, non-toxic and easy-to-use.
PRO: Has virtually NO fragrance but is very powerful. It has a light scent in its container but leaves the air merely smelling fresh — like after a summer rain.
