Hey welcome to the forum. Its apparent you have some skills. The person that posted about the mylar is spot on in this case, you have a fair amount of bulbs there, instead of putting individual reflectors on them to direct them, you could construst a sort of tent around the outside and install mylar (90% reflective) or Panda Plastic (85% reflective) to reflect all that nice light back to your plants. You should also check the thread Garden Knowm (SeeMoreBuds) posted about light proximaty with the clf's.
Please change this to a journal, more folks will view it, I know I will watch this one. VV
