Athosanswered grow question 5 years ago Let's see. Your area is 32" * 32" = 2.67' * 2.67' = 7.12 sq ft. You need 30 to 40 real led watts per sq ft; so you need between 213 to 285 real watts. Two of those 1000 watt giixer will give you 220 real watts, which will be just over 30 watts. So no it is not overkill, it is barely enough as it is.
