Meijiu quantum board advice

[charlie_andrews]

Evening all. Currently using meijiu 550 v2 rpec 550+660nm. Had light on around 50% all through veg. Looking great. Should I wack them up to 100% straight away now I’ve flipped to 12/12? Or gradually up? Appreciate any advice.

Thanks in advance

Maybe someone will chime in soon, but I got the 320 watt running at 260w. I'll have to turn it down some more during summer to get rid of some heat. Or upgrade exhaust, but this is what I got so far.

In a 2x4x5. Purple punch bag seed.

I've used my 480w version of that fixture in my 4x4. Seemed to work best @ 20". I just poured the coals to it when I flipped.
