I'm moving up to a slightly larger tent for my next grow, 3X3 feet. I've got a PG260 LED panel which I suppose is enough, but I'm thinking of adding some extra light. I've come up with two possibilities: add a 150W HPS during flowering, or stick a T5 tube vertically in each corner. Or, I suppose, two foot tubes horizontally on the sides. Which of these makes the most sense? Or do you have an idea that tops both?
