No, not genereally! My results improved the most because I'm using lots of F-strips and low driven COB's now with only 12-14" maximum distance. Without the UVB bulbs I could use them with only 6" and would still have +80% uniformity.
With low driven COB's with or without 660‘s one can for sure reach the same distance and level of efficiency so I would not say 3k is a better spectrum. But what happens when you mix 3,5k/CRI80 COB's and 660's? You come close to 3k/CRI90!
This and the YPF performance of the 3k F-strip spectrum was the main reason I've changed.
@Rahz has done a lot of spectrum tests and 3k vs 4k vs 5k comparisions and he also got the best results with 3k no matter if it was CRI70, 80 or 90. 3k always yields the best.
And I've to agree, 3k seems the most productive spectrum.

Lol!
61°F today and you can already feel the sun...

Enjoy it, go for a polar bear swim...

The funniest part here, we have less than a half inch of snow on the ground and forecast currently shows only another half inch expected....

It’s what happens when you live in a place where you hardly ever see snow on the ground, and it falls at daybreak/sundown (high traffic/black ice)...

And of course additional monos are helpful because the offer the ability to communicate with the plants. Deep red is the most efficent LED color and adding deep red improves over all efficiency and it has positive effects on colours. Far-red gives you control over the stretch and in combo with deep-red you can profit from the emerson effect and better leaf temps. Exspecially with usually used intensities! Blue has a signaling effect and can be used to keep the stem short and increase the number of nodes. Directly directed on the stem you can get up to 10 nodes on a 4" high plant. Purple and UVA wavelength also have effects on nodial spacing but also help to bring out more colors. Especially UVA is known to have a huge impact on the terpene profile and a plant getting UVA can smell much more intense or even completely different.

A perfect lamp would have all these wavelength tunable and of course a white base spectrum. For us hobbiists it depends on which degree of control you want to have. I have already a separated 10w far-red channel for EoD treatments and for the 2nd half of the flowering stage and today I've finally got the 12 Osram Square series diodes in deep-red so I can add another separate string of deep-reds. 60% efficiency at 700mA means 60μMol/s PPF out of only 20w. That's 3μMol/J at 700mA and 3,94 at 350mA. A nice efficiency boost if you ask me!
Imagine a 200w COB light with 2,0μMol/J and add 100w deep-red with 3,0μMol/J and you would have 300w and an efficiency of 2,33μMol/J.

Literally the same here since at least the last 20 years. I remember times in my childhood where we had snow every f..... year enough to ski or toboggan the whole winter. I always had to help clear the yard from snow and that took hours.
Often more like 20" overnight! And today there is almost no snow. The coldest temp this winter was -2°C at night where I life and the little bit what comes down at night was already melted away a few hours later. And I've the feeling it goes faster and faster.
Half of the migratory birds like starlings and so stay already here because they find enough food. We even had some hurricanes this year of course only smaller ones but with enough power to devastate a little town. No house here was built to withstand hurricanes, lol!
The whole climate change is an exponential increasing process and I'm pretty sure we have already reached the point of no return. Even if they reduce the global CO² emissions in halve the process would be unstoppable...
We could maybe slow down it but we can not stop it. For that the world population would have to be cut in half too. For me, it's only a matter of time until we have deprived ourselves the base of life.
Maybe in 400 or 500 years when we have successfully conquered the Mars and maybe IO too we can get the Earth back and make it usable again, LOL!

I hope not, but unfortunately climate change is real and we americans have failed to face up to it...we care more about ourselves than our offspring and theirs...and we elect dishonest buffoons to further ignore it....

Our children will pay for our greed... and stupidity.

I like that it was global warming but now it’s climate change lol.
Anyways though it is snowy on this side. I’m still waiting to see if I work today. The airport is waiting for some radiator part to open.

Global warming, climate change, diff names for same effect in our blue planet’s grow tent....

If any grower doubts the effect of co2 and temp, they don’t understand squat about what they’re doin....

We’ll see, imo, lights like the 96e’s are gonna give this mindset a run for it’s money,they can stop height extension so well (without excessive heat or burn) and bulk up buddage so well, that our obsession with having lights practically at leaftip will not be the same concern as in the past.

Thing is that diy'rs need to understand that running them higher then 130w will leave them in DE then SE hps zone as far as efficiency is concerned & that was the word of the year last year. So realistically 100w pads to be where most of us wanna be.
Got par #'s for 100w?. That'll be like 2.2-3 umol/j if Shanes (MiGro) #'s are correct. Theyre usually a tiny bit lower then advertised.
My Plants reacted well to them.
Need a few more runs to tell if i like the spectrum. The green spike in the 4k makes me nervous & is usually why some mix high & low k temps to achieve the 4k. Then enhance it. We'll see.
