Lumens is not the same as photon count (uMols or PPF). Lumens value is heavily biased toward green light. A light can have a higher lumen value but lower photon count if it has a lot of green in it. Plants use photons not lumens. You simply cannot really compare the lumen values of different CCT spectrums.
Well that is EXACTLY what I said and indeed what researchers have been investigating. They conclude that "quality of spectrum" has little to no impact. Not theorizing like you do though, but cold hard facts.
If one spectrum grows/flowers better then the other then indeed it is more efficient at what it's job is no matter the data #'s & theories.
And you, see what I have to deal w/ when you pop up telling truths n shit. Then your gone, back to growing mad bomb w/ your Amares n I'm here listening to guys like that spin everything around so they can look like they saved the day.
Thing is, there is no reliable evidence that any spectrum really is "the best". At best there is some anecdotal evidence showing one spectrum is slightly better than one or more others and then there is other anecdotal evidence showing completely different results.
You sure sound like someone who spins everything around so you can pretend you saved the day ...
Si, but it gives you an idea of the light's efficiency and output. As previously stated, green at high intensity can replace red. A fact proven by the "inefficient" HPS, according to the "experts", test and research often referred to as facts. If you can accept the HPS is effective at growing cannabis, then you have to try to understand and accept on how and why it works.
You actually believe this nonsense? Hope others do not based their lighting purchase decisions on these misguided facts . If the "quality of spectrum" has little or no impact then why did the original "efficient" dual 440/630nm or 470/660nm blurple spectrum failed so miserably hence why they started adding whites to fill in the spectrum? Also, if this is true, why did you mentioned previously that the HPS spectrum was "inefficient"? Again, you're basing your assumptions on misinterpreted and generic "research"as "facts".
No, it REALLY DOESN'T. Not with different CCT's. If you want to compare different luminaires of similar CCT spectrums, then its a useful yardstick. But because of the strong green bias of Lumen measurement, "a little (green light) goes a long way", and pushes the lumen value much higher than it pushes the PPF or PAR value. So a higher CCT luminaire may look more efficient in terms of lumens per watt, but may actually have a lower photon count in uMols/s.
There's certainly plenty of threads on various forum w/ side by sides showing one spectrum outperforming another by a considerable amount.Thing is, there is no reliable evidence that any spectrum really is "the best". At best there is some anecdotal evidence showing one spectrum is slightly better than one or more others and then there is other anecdotal evidence showing completely different results.

It's hilarious how you, yet again, do the exact thing which you accuse me of. You provide no facts other than your opinion.
Yes and then others showing the opposite. A hobby grower doing a side-by side is anecdotal anyway. There are way to many variables involved.
Again, I agree with what you're saying, but I was referring to a white spectrum at high intensity that green plays a major role in the spectrum efficiency and overall results. This is why HID also refers to lumens. Was not referring to comparison. I think we beat this one up pretty bad already. It's time to let it die in peace. Cheers!
Not a lot.. It just floods the floor and drys out in between waterings..
Damn DH sorry to hear your still having issues.. Are you still doing PPK? My nutes do stay stable as hell, and i like my PH 6.0 to 6.2..
I did the same shit went from 12 to 9 plants was still a little too much with the 16 day veg. Now I'm moving to 6 per 4x4 I was going to give it an extra week veg but after hearing this they are just getting the 2 weeks. I love jacks nutes all the organic growers I know always comment on how good my nug tastes compared to their organic nug.
im getting back on track finally! its been bad luck after bad luck lately. tried out some coco trying to see if simplifying was the answer but i got a bad batch of coco that was salty as hell and caused lockout. took me a while to figure out what the hell was going on. first is lightened the feed and they got worse so i stepped the food up. still got worse. someone told me to check the runoff and it was sky high. been flushing every few days pretty heavy and they have absolutely done a 180. new healthy green growth on all plants. went through and defoliated and removed all the damaged stuff i could get to yesterday. today im gonna go through and lollipop. these are getting flowered in about a week. ive been too ashamed to post pics until they recovered lol. it got bad there for a while and i was questioning all my life choices lol. at least this happened in veg and not flower! from now on i am logging my ph/ppm in and out on a weekly basis to look for trends.
I had to back off from 200 to about 80. the plants still look a tiny bit shy on Mg but no more calcium problems.
Jacks is the simplest I dip my clones in full strength jacks 321 it doesn't burn them and the same ratio gets you to the end of flower.
