I've run blue lamps for the past four days consecutively and have seen the Asian anubias sprout three leaf nodes on each stem where it previously would have taken approximately a week to grow one leaf node. I have shifted now to running red only light to see it's effects. My tests are on a shrimp tank with only the Asian anubias, crypts and hm both floating and carpeting with no ferts or co2 atm.
Just adding a photo of my test setup:
The results are remarkable.
Peacock moss has grown new buds in a matter of days, crypts have stopped melting and new growth seen in the past three weeks. unfortunately my timer has gone on the fritz so my lighting schedule revolves around my work schedule which is fairly erratic so the test is on haitus for now.
