I don't know how many sprayers I've thrown in the trash after two or three uses. Anything sold at the hydro stores is garbage, Lowes, Hone Depot, ACE all carry the same garbage as well. I am beyond frustrated with this. My problem is that they clog a dozen times when trying to spray anything other than plain water. Haven't been able to do a good foliar in a while. Have three of them that I throw at the wall before I give up. Fucking not in a good mood anymore today.
