Awwww quantum or go home love my board

Hi all,

I am new here. I am going QB and DIY for my first grow. My 4x4 tent just arrived and I have decided on using 2x HLG 260W (QB with Samsung LM301B diodes).

Question: They come in both 3k and 4k spectrum. I was thinking of getting one in each spectrum but not sure if this is best idea. Erik at LEDlightsdepot said 3k for yield and 4k for quality. My goal is quality more than quantity but ideally, of course, I would like to find the golden mean :)

Any thoughts, suggestions? All are most appreciated as I this is my first indoor cannabis grow after years of outdoors organic heirloom veg/herb growing!

Thanks very much Chris Scorpio.

I'm leaning that way. My only pause is that I have a new Mars Epistar Pro II 400W with plenty of red so I thought of getting one of each spectrum and using the Mars as supplemental red for flower.

But, I am barely a seedling now in terms of grow knowledge so happy to get more experienced advice/feedback, suggestions.

And btw, fine looking pooch you have there.
