I've got one SOL Nano over my tank and it so far has done a great job with the SPS I've added - all of which came from tanks that utilized halide lighting.
I don't think the truck hauling a boat is really a fair analogy because there are so many more variables at play while growing a living creature in a glass box vs simply pulling x amount of weight with a machine.
I would also add that SPS frags can change color, growth speed and pattern and/or look different under MH lighting when placed in different parts of a tank. Merely snipping off two frags from a colony and placing one on the left side of a 120 gallon and 1 on the right side of a 120 gallon tank could result in two different variations of color/growth in the same exact species of SPS.
I've seen a red planet before under 250w halides that was all red with no green...then a piece gets fragged off the colony and moved to the other side of the tank, (almost the same exact height), and it turned green with just a tinge of red/pink near the polyps.
Same thing with other frags taken from one tank placed in another tank under similar mh lights.
My buddy got a frag of some sps that was purple under the other guys lights and it turned turquoise in his tank. Both have metal halide 250's.
There are so many factors at play here - between chemistry/calcium/dkh/phosphates/magnesium/ph, salt mix, bulb, ballast, lighting schedule, light height, coral placement, food, flow, temperature - all of which having an effect on the coloration and growth of a coral - that I find it difficult to place all blame on the AI's. Especially since I, the brownest thumb (ok opposite of green, whatever lol) in the world, can grow SPS under AI lights...
