Its actually an opinion and a claim - based on an observation. Here is another observation - the vast majority of people who have read the poll and taken it are not - and are not planning to use MH lighting. Why do you think this is? Not a rhetorical question - I'm just wondering if you can step outside your opinion - and try to think about why others don't agree?
I know this is not a question at me, however I do have a great example of someone who went MH recently then away. In our local forum he posted about lighting options and we talked in some detail but he was pretty convinced to switch off his lighting at the time to MH 100% because of a few very convincing people here on reef2reef despite my best intentions trying to warn him it may not be quite so cut and dry.
Well about 2 months later they were all for sale - heated his office up far too much without any noticeable improvements. Granted 2 months may not have been long enough to see any presumed improvement, but was long enough to experience disadvantages. Don't know if he ever sold his nearly new equipment, I'm sure was am expensive lesson.
