Yes it stinks, I've used it in soil. It gave me the tastiest buds to date. Its hard to come by in my area though. It takes a good 2 hour drive to anywhere that carries advanced. I was skeptical of using it in hydro the employee at the store said no, and someone here said to never use organics in hydro. So i called advanced and they said as long as its not in aero its fine. Adjust to 5.6 every couple days if its in the rez and top up with plain water. I'm gonna give it a try in the E&F and see how it does. I may do the second tray in sensi a & b though. Just to see side by side which works for me better.
