Very nice Gnome, thanks for the post! You may also want to try adding a black light or reptile bulb instead as an experiment because they emit uvb which is what causes the noticeable increase in trichromes and are much cheaper to run. I'm sure there are other benefits to the MH with increase in the blue spectrum keeping the nodes a little tighter and more compact. I'm thinking of supplementing with a MH or something else just to see myself.
