Popping my forum cherry here. I started with a Vivosun 4x2x5 tent with Spider SF2000. I realized that the tent is too small so I'm upgrading to 4x4 and keep the 4x2 for seedlings/clones. Definitely looking at my lighting options. Thoughts on 2 more SF2000's? or is the 600W Kingbrite @Billyjob007...
