You've come a long way bro, lookin' good.
Just a little FYI for ya.
From the journals I've read using LED, the consensus seems to be you need the same wattage as HID to get good flowering results with the LED. So a 180W LED is not as good as a 400W HID. If you get good results with 400W of HID, then you should get similar results using 400W of LED. LED results are also dependent on the angle, the wider angle 120's cover more sqft but do not get the penetration.
I'm currently watching Setting Suns LED vs HID grow with approx the same wattage. This grow will answer alot of questions. BeIre and IrishBoy have journals using LED with great results.
For me, I just cant see dropping $2000 on a LED when $600 for HID, AC Hood, and Vent Fan do the job.
