Hey guys so I just set up a new planted tank 20g long and I have two light fixtures running on my setup:

• Current USA Satellite Plus Pro
• Current USA Serene Sun LE Pro

As the spectrum for both is programmable, what is a good balance for the most optimal growth? They have adjustable White, Green, Blue, and Red but I don't know what percentages to have each color running during the photo period. Currently have them at 100% W, 75% Red, 50% Blue and 25% green. Should I Just crank up all colors to 100% for daylight?

Your expertise is greatly appreciated. Thanks in advance!

Highest PAR/watt in general is red/blue, then white, then green.
They all are used.

Choice depends more on what your system can balance out, not ultimate level of PAR.

But to answer it yes the most par is w/ 100%.
If one wanted to maximise watts to par skip green.
Again if the most is good or bad depends on CO2 and nutrients.

Don't forget about looks and there are some things one can change like tall ve short growth w/ light "shaping" but not part. important.
