I run 600s at the same distance.I suppose that what it comes down to is how much work you are willing to do. The 3070s are very easy and quick to assemble (except the sanding part if you plan to flatten your heatsinks). There is no doubt that 3000K produces great results on its own. That said, adding some deep red and deep blue may improve the quality of the buds even further but increases complexity. So I settled on something like this (COBs should be spread further apart)

When I was mixing HPS with LED I set them up side by side because the HPS needed to be so far away from the canopy that the LED modules would block the HPS light. Another option is to surround the canopy with LEDs and HPS in the center. So mounting the COBs up high with the HPS would be problematic. For reference my COBs are only 8-12" from the canopy.
complexity isnt an issue, im a service tech by trade so im good there, I just dont know what way I should go. I can pull a pound per 600 pretty steady, id like to bump it up to say a pound and a half with supplimented diy led for the extra frost, im not against going complete led but I dont know. I run my 600s around a foot so the 3070s would work but I guess I dunno if 4 big r-w-b panels would be a better bet than either hid+3070s or all 3070s. I dont ask for advice very often here but this question has me stumped. what would be your ideal set up to pull a pound n a half out of a 4x4?I suppose that what it comes down to is how much work you are willing to do.
