Bullshit. Nothing more than conjecture and anecdotal evidence. As Roach pointed out, you have no scientific evidence to back up any of your chest beating bullshit. Now who looks ASSinine and desperate to win an argument?
Back to the spectral graphs posted. Since reading comprehension is not your strongest suit, I'll reiterate my point - both MH and HPS are full spectrum lamps. Also, if you think I'm going to believe any one of the sales pitches from folks like Hortilux, you're crazy. Mama didn't raise no fool.
Years ago when I was researching and sharing my stuff in some of the old forums like OG, I kind of pioneered the incorporation of 600W HPS...nobody was using them but me, and then it caught on. I asked the techs at Osram Sylvania who were the FIRST developer and marketer of the 600W HPS to share their spectral graphs for their regular HPS and their so called "enhanced" HPS, the one with the "added blues". Guess what? Both graphs are the same. I've posted talking points on this stuff over 15 years ago, probably while you was still messin' in your drawers. Their enhanced lamp was called "PlantA-T". Here's the graph:

Now, being that this has taken the path of another RIU pissing contest headed up by some know-it-all kid, I'm not gonna hash it out for the hundredth time, which happens over the years with every new crop of newbies. YOU do the research. Start with photomorphogenesis and check out the blue side reflecting panels in some of my garden photos. You don't own the rights to "experiments". I've done more experiments on cannabis than Heinz has got pickles.
