To the OP...why in the world would you try and discount decades of research because you read one article that looks pretty? As someone said before...do an experiment and prove yourself wrong. There are grow journals on this very site and all around the internet with side by side comparisons. It has been shown time and again that a CMH bulb is the best bulb to use in any phase...if you can't do that, stick to the conventional, proven way of doing things. Look a few up, then apologize to everyone here at GC.
