I am setting up a 4x8 tent with 2 600 watt lights. I was wondering if the Super Sun 2s are still considered one of the best performers? Or should I go with something else? Xtrasun 6", Radiant 6", Daystar 6"? This is my first grow, so I am currently trying to absorb a ton of info and trying to make sure I try to get things off on the right foot and not waste money in the long run by buyig crap.
