James:
When you can grow the red pigmented plants which you see in mm's tank you will definitely have a green thumb (I do not have one yet)!
Folks:
Some of you may not be aware that green chlorophyll is much more efficient than red chlorophyll in the generation of chemical energy from electromagnetic radiation.
For the naysayers of 7100K bulbs in a freshwater aquarium blue light as well as non-visible energy emitted by 7100K bulbs are very efficient in the generation of chlorophyll and the generation of chemical energy by the chlorophyll.
