Depends on what kinda light..Well what i want is at least 250watt's on at least one plant ...and i use compact fluro's ..to me grows just as well as HID'S and so on ...But i also have about 45 4ft compact fluro's gorwing 35 plants in my den that might be the reason why they grow so well ...(Yes i have an outragous lightbill i think like 350 a month)...But past coupl weeks i been replaceing the 4ft's with this http://www.wormsway.com/detail.asp?sku=CFSD110#....i mean there just awsome lights you could probally buy 1 and probally survive veg state..But 65 watts man i dont think so with 5 plants...Hope what i do will answer your qustion...And if your just a kid save up your money man and buy 400watt HID
