I just purchased some Zero Tolerance from my local hydro store and I was told to cut it in half because it would work just as well and that it would last longer. I waited to apply it because you are supposed to apply it shortly before the lights go off to prevent burning. Has anyone ever used it? Good stuff? What did you use it for/results? I was trying to search around for some ideas on strength of dosage. I've got 6 ak47 I want to use it on for fungus gnats and what ever else I may or may not have. Thanks!
