I have been kicking around some other lighting options in my pc case growboxes. I currently use 2-23w 6500k & 2-26w 6500k cfl's in my veg box & 3-26w 2700k cfl's in my flower box. I would like to update the lights so to maximize my yield. I have to grow the way I do cuz of personal family reasons so upgrading my grow space is out of the question.

What should I use? LED or cfl?
