What I’m saying is that if you had a lamp that was under powered most of what any meter would see is red. Because it takes less energy to power the red spectrum thus giving a false sense of power to spectrum ratio. So let me give you an example. If you had two reading one a 1000 watts and the other 600watts same lamp. Reflector and ballast. The 600watt being a 1000 watt lamp underpowered. You MM reading would show a higher par per watt reading. Because the par-meter is picking up more red. Red is easier to deliver because it takes less power and heat (K) to achieve/ I should have been more clear. But it seems like you wanted to prove your lighting knowledge which is true but you did misunderstand me. I was addressing a par meter because it had been a common topic in the last few pages as most home growers or even commercial growers cannot afford the 10k-100,000 k light testing equipment. I still think a par meter is a great way to keep an eye on your canopy saturation and light on target. As long as you know the technology you running is powered to its potential."any light with higher reds will read higher on a par meter."
don't think that's true, as you would first have to take into account the par meter, and how off or not it is in a certain area / region as no par meter is 100% accurate, but the LI-cor is what all "scientists" use, and is the most accurate picture.
in one definition of your statement, yes a more wattage bulb is going to read higher par, but I think you were meaning red counts for more on a par meter then the other colors, and that's not true.
If I were to give you a par reading of 2000, and asked if it was a good light, what would you say? now what if I told you it was a all green led... any range from ( I'm simplifying here as meters are not accurate ) 400 - 700 get's counted the same on the meter, that's why a par reading is worthless as I mentioned above, but really only useful to use as a basis to say, ok that's the PAR number and this is the plant growth I'm seeing, or to see what different areas of the canopy are getting.
a high par number doesn't mean squat, without a spectrum chart / spectrophotometer reading. PAR has got way too hyped up since it's take over from lumens, but people need to understand it's one part of thee picture, not the whole picture.. and even then what you can do with a par meter, you can do with any meter, as all your after is a base line to go off of.. but it's not as cool to say 8000 lumen vs. saying I have 1000 par....
looking good bro
Looks great, coloradoe! I'm obviously going to have to break my screen back out after I get tired of experimenting around with full-sized plants.

Are you flowering under the CMH too?
not YET, but YES i plan on it
