You can go cmh or you can buld 600W (12 diodes) of vero cobs for that price and get more light/spread if you are into a "light" project. :fire: get half 3500k and half 3000k should be good, will give you more headspace to grow vertical. keeping plants too short in a tent with too much blue can also hurt yield. thats my 2 cents.
those 50v cobs need active cooling for sure.I've thought about this and decided instead on building some lights based of the Citizen 1818. I will build the first half for a 5x5 now with no tent (expensive all at once), then build the second half. I will base them off the MeanwellHLG-600H-54B. Half will be 600w and the other half later will be 600w giving me 60w/sf in a 5x5 tent. I checked spectrum and 3500k is very good for what I should need. This driver is dimmable with a 1000k pot too. I will run each chip with a reflector instead of a lense. I'm just wondering if I should go with active or passive cooling for each cob if I plan on running them at around 75w each
Someone from here told me about growmau5' 100w qb "pucks" last night and I am looking at them now too. supposed to be cob killers
