Im realizing i might not be able to control my temps and was wondering what thoughts anyone with knowledge may have on light output and spectrometry, color range. If i Underclock a 1k to 65 % 70 % to find my heat limitations. I was hoping to have four 4×8 banks each lit by two 1k ac hoods. But fear i may have to go with two 600 watters in my 4×8 banks. I know hortilux doesn't recommend underclocking they're bulbs but a 600W ballast costs the same as a 1k and if i get proper air conditioning im hoping i can bring up to 1k per 4×4 area, ie 2k W per 4×8 bank. Any suggestions help or feedback is greatly appreciated.
