It’s difficult to say with certainty which type of light—white or red/blue—is better for plant growth.
Red and blue light are the two most useful for photosynthesis. However, other pigments found in plants absorb various light wavelengths and subsequently convert that energy to chlorophyll.
This indicates that while red/blue light is necessary for photosynthesis, white light also contains other wavelengths that are somewhat helpful.
Besides, the ideal option also depends on factors like heat, intensity, and efficiency.
All in all, one thing is for sure, red/blue LED lights are the best value for money since they are long-lasting, highly efficient, and low heat.
