Are lenses necessary?

  1. I'm growing in a reflective tent. If I don't put a lense on my cobs I assume they'll spread their light. I think lenses would only be helpful for cobs closest to the walls because I also think light reflected off of mylar walls reduces it's efficiency when it finally gets too the plant.

    Anyone use cobs without lenses?
  2. Also Im going to scrog as always. I believe lenses would allow for better penetration in the areas it's focused on. But for scrog I can't picture a benefit during vegetation. Maybe there is a benefit during flowing.
