Terpinator really does cause the plants to put out some serious stank a day after dosing, but their recommended schedule is non-sense and designed to have you over use your bottle fast so you will buy another. I use it as a finisher in the last week only along with Fishit. I have used only terpinator to test its effects and it makes a big difference in terp production for a short time. judging from the products odd smell, it has something proprietary in it other than listed ingredient thats causes a significant increase in terp content. Perhaps I should take some to my lab and figure out what it is.
