Thanks for that info, what if I were to use the hlg-480-24b for the Samsung strips in parallel, and then separate drivers for the reds, far reds, and blues? From my understanding, which idk if I’m right, but in order to be on a separate channel for those controllers you need a separate driver for each channel?

Yepp! Instead of one HLG-600h-24 you could use for instance a HLG-480H-24(for white) and a HLG-120H-C700(for colored strings). That way each colored diode gets the same current and you don't need to worry about thermal runaways.
Or if you want each color controlled separately you could use a HLG-120H-48 as main driver and small dimmable Meanwell LDD driver for each color channel. These LDD's are available with 350-1500mA and with 38 or 52v input voltage, offer pwm dimming(5v) and can be dimmed to 0/off.

But you'll lost some effiency with such a driver set up. The HLG-120 is 93% efficient and the LDD's up to 96 or 97% if I remember that correctly, so 89,3% or 90,2% driver effiency in the best case, which is still pretty good.

is there a more efficient power supply for the ldd drivers? i dont really understand how these ldd drivers work and cant seem to find any videos on them

also, can i dim a hlg-480h-24b on a bluefish controller?

I usually find 5 to 6 geniuses on here a day... I try to keep up with the things you all are doing and are talking about, but then the Einstein thing starts to kick in and Im a stranger in a strange land... I think thats an Iron Maiden song... Anyway, you guys have a lot of knowledge about this stuff and to me that makes you all geniuses... Mad props to you all from Frank Nitty!!!

thats a vague question

certain wavelength ranges of uv and blue can stress a plant to create more resin but need to be applied sparingly

wow.
some guy put high quality uvs on this flowering stage and he got crystal buds st the top but 30% reduced quantity
