Voodoo does work, but of course they say you need the tarantula and Pirana to triple the price of the whole ordeal. With much research I decided to buy White Shark, which has most of all the things that Voodoo, Tarantula and Piranha have bug wise. To feed this mess, it is recommended to get a carb-rich element ,which I use Botanicare Original Compost solution, to supply any possible micro-whatevers and carbs the roots may need. Others will say you need AN's Bud Candy. I have no idea what you are growing in but I am experimenting in pro-mix. With the Shark I am also using air pots, a natural way to increase root mass.. What medium are u growing in?
