I saw your grow log, and I'm interested in how well those panels do. That height recommendation seems high to me. That's 4.5' to 6' above the plants, I am not sure you are going to get enough light energy to the plants from so far away. I realize that will give a very large footprint but at what light level?
Do you know how many diodes are in it and how many watts each they are?

You can post your answer on your grow log thread, and I'll catch up with you there.
