I've been hearing that when it comes to micro growing or cfl's i dont remember right now, that you count lumens and not watts, if i am correct in assuming this how would go about determing how many lumens i need for my cab (48inx36inx24in), i am certain the cfl i am gettin from 1000bulbs.com are enough for this cab, but i need to know what some people are pulling(drybuds) from their cfl cabs......any input would be great, the bulbs are labled at 6900 lumens i think there 125 watts.
