Yo lo del 30% del compañero creo que es porque acaba de cambiar de pantalla y va a ir subiendo poco a poco, no lo veo mal. Yo doble los watios de mi acuario de golpe sin ir poco a poco y queme la.mitad de las plantas y llene el acuario fe algas.
En cuanto al color, por lo visto el rojo y el azul son los espectros que mas utilizan las plantas en la fotosíntesi

corregirme si me equivocó
Añado :
Blue Light
The most important blue wavelengths are from 430 to 450 nm. This part of the spectrum is also known as cool light. These wavelengths encourage vegetative growth through strong root growth and intense photosynthesis. Blue light is often used alone during the early phases of plant growth, such as starting seedlings, when flowering is not desired.
Red Light
The longer wavelengths of light are red in color. The most important wavelengths in the red spectrum are from 640 to 680 nm. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production. The red wavelengths are known as warm light, and they are naturally more prevalent in sunlight during the shorter days of fall and winter.
Green and Yellow Light
Some of the green and yellow light that reaches the plant is reflected, giving the plant a green color. While most of the absorbed wavelengths are in the red and blue ranges, plants do use some green and yellow light in the photosynthesis process. A light source that provides light in the entire visible range will better meet the needs of the plant.
