i ran Terpinator for a few years, and used to swear by the stuff, heres the issues i had, it seemed like the plants stopped bulking up and started to frost up....i had some of the stickiest chronic ever, but the weight wasnt there....i actually ran outta Terpinator, and didnt have the extra cash at the time to get it and ran with out it....that run was 10 OZs heavier if i remember right......never went back to using it. its a organic stressor than stresses the plant on a molecular level. also bewarned that stress did cause a few strains to herm out at full strength ...i always used it at 10MLS a gallon and nit the recommended dose.
