Hello Bud, Sharing a first look at my L2 Rev4 Setup. It has been running for 14days. The first 7 days I had running at 50% for 12hrs on and 12hrs off. Didn't see any growth until I raised the intensity to the 6:00 clock position. I left the duration the same 12 on and 12 off. I saw growth on the 9th day and here is the growth on the 14th day. I raise the intensity to 7:00 clock today after lightly cleaning the screen. Please let me know if this method is the right steps to seeing awesome growth?
