Biomanjcs72,
Yes, this should be plenty.
320 Watts of light on a 110 = ~2.9 watts/gallon.
I had good luck using 3 x 150 watt Iwasaki MH lamps on a 135 (6’)
Which = ~ 3.3 watts/gallon
Also, the same lights over a 180, Which = 2.5 watts/gallon.
I was also using CO2, which made the plants grow like crazy.
Regards,
Scott
