@Time2grow GreenPlanet Duel Fuel is what Grobo was designed to be used with. They diluted it and resold it to us. I am on my 2nd grow using it undiluted and its going better than any of my Grobo grows have before it.
My current grow (Marley Natural Blue Dream) is hitting the lights, I’ve never had that happen before. Its using Duel Fuel 1 & 2 in Grobo bottles 3 & 4. And GreenPlanets ProCal in bottle 5. (still have plenty of Grobo 1 & 2, PHup & PHdown)
