The only reason I say that is because a buddy of mine uses one UFO for veg(a cheap chinese one too), and in 3 weeks to a month hell have 15"-18" plants easy, maybe a little bigger, and he stretchs that things light coverage area so thin too, he puts like 6-12 plants or more under one in 5 inch pots...once they hit 15-18" they either go outside, or he transplants them to 3 gallon pots and mothers them out to take clones, and once in 3G pots, he can fit 4 full size plants(18-28") under one UFO....to have two UFOs AND 2 cfls to me for two little plants just seems like a complete waste to me, redirect that electricity torwards proper ventilation....but my buddy has great air movement & ventilation with a proper exhaust/intake system, he also uses a soil less medium(sunshine#4) and adds his own nutrients though....which is the way to go in my opinion.
