And good breeders will label those conditions right with thier product. So the consumer knows that’s the ideal area the strain is used to.Yes it should if the breeder nailed the parameters before breeding.

You mean outdoors. Sunlight is sunlight whether you're in the US or the Hindu Kush
I think what you are referring to is photoperiod which has nothing to do with spectrum
Now you're confusing me. I thought I had a grasp on Kelvin, 3000ish for flower and 6000ish for veg, regardless of cmh or hps?Im not. Im saying that my hps grown and bred seeds that were bred starting 15 years ago with hps bred old classic strains and hybrids from a decade earlier. Grown with hps.
Sorry for that paragraph. :)
Im saying i will likely get the potential of these plants with hps. Any gains from spectrum may be nominal.
And with cmh 315 vs 600 hps for me it was mostly hype in practice.
Except for the effects of higher blue range in flower. They were noticeable.

Well that sucks, yet another thing I thought I understood shot to shit. When bulb shopping the only info I ever see is watts and Kelvin.No spectrum mix is way more complex than that and is measured in NM not kelvin. All Kelvin is, is when you take a black carbon rod and heat it, it glows certain colours at certain temperatures. Degrees Kelvin actually tells you nothing about spectrum

This growers view on things can be found on post #89 of this thread!;)Lol you've just actually confirmed what I said with "Except for the effects of higher blue range in flower. They were noticeable."
Its good chatting btw because I appreciate getting growers views on things. It gives me better insight into where people are coming from with their views and yes there's a chunk of hype getting around about the 315 W CMH punching out as much light (PAR) as a 600 HPS. They don't. This has been demonstrated. Did you btw notice better resin production with the 315 CMH?
True you do get what is called phenotypic plasticity; however deep in the DNA key things remain the same or thereabouts. Certainly you noting HPS raises this because if you haven't noticed HPS makes plants stretch and results in less than optimal yields which is why combining MH and HPS helps with yields and quality. Now new lamp types such as CMH are emerging etc. All studies actually show that in growth chambers for optimum plant health HPS requires about 30% more blue light (which is typically added through MH).

I believe this to be true e
Yes that is the best combination for compact leafy veg and good flower response. But it is just like using mh and hps really.
That's what I like about CMH - its 2 in one with spectral uniformity so no overlaps and all light is equally as good. Thanks for the feedback on that. I'm impressed with CMH myself but run 630 watt. For now I think CMH is the future of indoor lighting but let's see what else appears on the scene in the coming years.
I read back and saw the kelvin comments. It is true different lamps with the same kelvin temp can have very different spectrums.
But spectrum charts dont show intensity. Most are set at the bulbs max so the graph doesnt show how strong the peak really is relative to other lamps.
Light companies are trickier in marketing than even cannabis specific nute companies.
I think multiple 315’s would be great and maybe overcome the lower output with overlap but i really like the phillips 3100k combined with the 600 hortilux super hps better.
Even the 3100k has a little too much blue to flower for me.
I may try the ceramic hps.
Why not run the 630 watt CMH? They pack a punch - a lot more PAR watts than a 600 HPS
