Anyone run 3k in 4x8s, started off with 2000s which are sunsystem yield masters, just wasnt enough intensity per square ft for the yields im use to, so i added a 3rd 1000w cooltube instead of my ducting connecting the 2 air cooled hoods , has 6" inline as intake and 8in outake for exhaust temps stay 76-81 tops....ps. The pic that shows the lights was when i wasnt dialed in, diff between 2k and 3k in 4x8 is nite 20201204_090841_HDR.jpgScreenshot_2021-02-04-15-25-02.png20201030_125620_HDR.jpg20210125_084751_HDR.jpg

I actually didnt get any better results from 3000w compared to 2000w , around 20-24oz is my best ... the heat works against yield too much for me ...id suggest 3000w without the tent imo in 5x10 area or 5x10 tent would work was just too much for 4x8....running a growers choice 720 roi and a hlg 550 rspec right now in 4x8 w damn near same results as 3000w hps ditching the 550 for another 720 roi asap though

I run 2 QB LEDs like the sf4000s and a 600 on half of my room heat isn't that big of an issue. but 3 1000w way to much heat I couldn't imagine that.

I'm kinda new so I'm not dissing but 24 ozs seem kinda low for that much light even 2000w I would be aiming for 32 a run but I will sacrifice some quality for weight
