I'm growing 2-3 plants in my basement in 5 gallon pales with DWC. I have the Lumatek 600 Watt Ballast http://www.progressive-growth.com/proddetail.php?prod=lumatek600-swtch, if I'm growing 1-3 plants should I just set it at 360 or 400 watts instead of 600? Or should I set it at 600, what would be the difference in growth rate? I don't mind the power difference as I'm only running one light anyways. Is it worth running on 600 or 600 Super Mode, will I gain anytime/bud size from doing this?
