sure it is.. ona just stands for odor neutralizing agent.. it is perfectly safe.. i am pretty sure that a superstore doesn't sell this stuff.. if you think about it, who uses this stuff... mainly just peps who are growing mj and trying to cover up the smell.. i know that you can get it online, but i know that you said you want it like yesterday, so i guess that will not help too much..
what is wrong with hydro stores?
