@Growmau5 Awesome brother!!! Driver control box is on point. IP65+ baby...now you can hose that side of the room off if you wanted after a run(or just for fun). Maybe just a dab of silicon in the wire through holes if you really wanted to get picky.
I support one more bar if you can do it. Should get you to ~865µmols PPFD...right in the money zone IMEO.
I've never made definitive actual comparisons between AT and cobs. AT causing a more purple/pink fade is the only thing that I've shown/proven. Apaches flowers look very good, and by personal preferences could "look better" to someone. That is all.
The one run they were all together...the apaches got UVB for 2 weeks...go check the pics...reason being because I knew that my apache flowers were getting entered in the cup. While the 4k only got it for 1 day(so none in my book)...and 3k got some slight UVB crossover, but never direct....Plus the whole garden was getting all kinds of crossover. There was nothing about that run that would validate any kind of comparison, there were far too many variable and no controls.
