There are a ton of led’s out there and some are better quality then most.
Me and @Graysin also suggest kingbrite from Alibaba, they are one of the few knockoff QB’s that have a strong reputation and produce great results.
Most led’s will grow but a true bang for your buck on quality and performance is kingbrite it seems to be unbeatable.
If you build your one from scratch it will be cheaper but most like to buy, HLG’s are high quality but you’ll pay for that American made high quality.
Close to them in quality as far as I’ve been able to gather, yet much more value since they are Chinese made with South Korean Samsung diodes. Are kingbrites.
So kingbrite is my recommendation.
A 4x4 bar kit would be ideal.
Otherwise. Two 320w boards.
You want 3500k option and the reds.
UV/IR is not needed but it’s nice.
I would avoid anything on amazon to be honest.
If you need something that’s trusted spec’s but still costs more but is easy to get because you can’t stand Alibaba. Then spider farmer is is good, but you’ll pay for the marketing.
