Home / GreenPlanet Product Support Forum / I’m running the gp3 in Coco running to waste / Reply To: Hey guys how’s it going? 🤙 Chasing a bit of advice, I’m running the gp3 in Coco running to waste. I’ve also used all the goodies ( resin, massive, liquid, etc). But I’ve been looking into Horti rawK and bud booster and was wondering if there is one you would recommend over the other to use? Maybe use both 🤷 Also is it normal to not use any PK and run massive instead?
