Thanks weedhound i have read that thread many times over the last few weeks. It is helpful for sure.

I have checked for light leaks in the past and not found any. I just decided to check again. ONe thing i did not do last time was to let my eyes adjust to the dark. I was in and out in a few minutes, sure it was dark. Well this time was different. I sat in there for a good fifteen minutes and surprise i saw two very very dim places of light. One is coming through a vent fan duct. This one is so far on the other side of the room from where the herms were present. And the plants closest to this SHINER have not turned. The other point is up on a sealing where some time has gotten loose and the top of a window seam is emitting the tiniest bit of light onto the ceiling. The ceiling is 10ft high. This is closer to the herms but still seems to be so dim and at least 8 ft from anything. Can a light that is so dim that the eye can hardly see it, turn a plant???????
