You're gonna be way short on light bro. Check the journal in my signature, (3) 240 watt LEDs plus (6) 2' HO T5 in a 2x4x6 box. That grew fantastic buds. If you check that 180w LED at the plug, it will only be drawing about 100watts. My opinion is you need to get up around 600 real watts. T5s is an inexpensive way to make up the gap, but you should think about 2 or 3 of those LEDS IMHO.
