Mixing colorspectrum samsung diodes.

Hi, I want to customize two 1000w fixtures and my Idea is to mix
3000k lm301h evo chips with
5000k lm301b chips
with added 660 and some 730nm.

but what ratio between 3k and 5k is ideal? how many % of white led should be at what kelvin?
Would appreciate any input! I want to flower under this fixture mainly, I dont care about veg specific spectrum!

Thanks

50-50 3k to 5k is exactly the same as 100% 4k

@Rocket Soul , any concensus on the subject?
I know it's been discussed many times

As far as i know youre correct but might be a bit different if using different make diodes.
This is based on some tests posted long time ago from hlg: 4k and 3k 50-50 results in exact 3500k.

I think the reason we see 5k/3k mix is for fabrication/comercial purposes: if you buy 5k and 3k as a company you can then make something closer to 5k or 3k by mixing proportions. If you go straight for 4k you cant play with the spectrum in the same way.
But there is no extension of spectrum, or "5k for veg/3k for flower" validity; the plant cant chose which light hits its leaves for obvious reasons.


Though reading back to OPS post, its evos veraus regs: id probably go for something with a bit more 3k evo than 5k regs to equalize the blue peaks, maybe around 60-40 to 70-30.

But at the same time id say that if i were making a custom spectrum id probably use different whites, im not super happy with how approx 4k + reds grow to be honest. Buds get nice and dense but not the same flavours as otger of my lights.
