Ok CFL lighting will never be equal to HID lighting. I have seen some people use CFLs with great results so dont get me wrong; but HID is going to give you more quanity and denser buds. A dayton fan would cool that Hut. As far as a scrubber only use one if you are consered about odor. And if you are but dont want to use a scrubber than get a strain that has low odor. Northern Lights has little to no odor at all. But if you need to mask odor than get a scrubber, but also i would suggest getting a inline fan instead of a dayton if using a scrubber. Does this answer your questions???
