Best cxb3590 color combo

For a flowering tent, what would be the best combination of color temperatures, and at what ratios? I've read through a couple threads and can only find people suggesting 3000k for flower. Well looking at the spectral graphs why not mix them?
I was thinking at a rate of 4 3000k : 1 4000k
OR something similar.
Please feel free to share your opinion or suggestions. Thanks

In truth I don't think we really know the answer to the question of which K offers best because its all still very much in the experimental stages and what we know about what plants need in regards to light is still very limited and unproven as well as constantly evolving.
The idea of a mix seems like a great idea, my thoughts would be that the closer we can come to an all over full spectrum as close to the sun as possible the better since that is what plants have evolved with over millions of years. What deviations to that and its consequences are not fully understood.
My guess would be thanks to legalisation in some places in the world the next ten years our knowledge on this subject will come on leaps and bounds. Nobody seems keener than the MJ community to strive for improvements and knowledge.
In general all COBs seem to offer an amazing range of spectrum compared to what we had over the last several decades.

I say go for it, rig something up and test it many times, one bonus is there's no wrong combination as they will all grow some nice plants.

Awesome, thank you for the reply.
I totally agree the drive for better cannabis will also drive the lighting industry for better spectra and efficiency. My plan is to do a 5 light 250 watt cxb with 3000k around the perimeter and 1 4000k light in the center.
I made this decision by looking at the cxb3590 spectral graphs. In my opinion, 4000 offered the high amount of blue and green light than the rest, and obviously 3000 went the deepest into red.
The overlap of these two colors on the graph made for a pretty curve. That's how I made my decision. I'll keep everyone updated as I get my light and grow with it. No plans for diy, I don't want the house to burn down. I see timber has a kit in just the design I want. Hmmmm

Soon cobkits will be having the cxm-22 in different kelvins i would go with those to keep more money in you pocket.they are 19$ compare to $30+ for cxb3590. you can tech get double the amount this way and get more light over your plants.

Interesting, thank you. I can't like people's posts yet apparently but thanks for the replies
