Yes, sorry I'm late. I used it in my last two grows along with the then new LEDs. So- my buds were denser, closer together, fragrance lovely. But due to Terpinator or LEDs or both? This time I am not using Terpinator as I have switched my nutrients. Point is I can't say exactly if it enhanced terpines. If I didn't switch nutrients I would use it again and may on the next grow. My go to hydro guy isn't impressed with it but my other hydro person is.
no help I know. If you have the bucks I would suggest trying it.
