I understand ... you have almost the same setup I have had (4x2x8), I wound up with sixteen 40-watt tubes (total 56,000 lumens), before switching to a 400-watt HPS ... there's no comparison, seriously ... what they don't tell you, 56,000 lumens of fluoro doesn't even equal 40,000 lumens of HPS ... here's why: a fluoro may put out 5000 lumens UP CLOSE, but, drops drastically, even inches away ...that's why we 'float' a fluoro tube an inch above the plant tops ... I had a chart once, that documented the lumens, as they 'fall off', with each inch of increased distance ... it ain't even close ... after reading it, I immediately ordered my first 400 HPS ... not too be badmouthing your setup, or anything ... it's fine :thumbsup: ... I'm just pointing out what works better, and why ... I used to get so pissed at everybody prodding me to drop the tubes, and go HPS, but, I'm thanking those people now ... good growing :thumbsup:
