Almost 3 weeks worth, I know to long but impressive. I can tell you that with the test I was doing with the LED's paid off. The 4 red 660nm side verses the 4 red 660nm with 1 450nm side comparison is now done. The extra blue side blows it away the other side was not growing off the screen as the blue side was. The all red side has about an inch growth past the screen. I was so excited to get these posted I forgot to get the all red side pics. The red had better growth then the CFL that's for SURE.
Pic of screen pulled from Scrubber sump. Notice the credit card beside the pics for size comparison.
Pic of the side scrapped.
Pic of the bottom scrapped to separate huge amount of algae hanging off the screen!!!!
