SAD therapy lights emit daylight colors, such as 5000K or above. The essential term is « lux, » as the right Kelvin and lux are required to have the desired effect on the human eyes and brain.
Plants have a distinct « need » because their goal is to grow and carry out photosynthesis. Blue light encourages a plant’s root growth, whereas red light encourages flowering. The key term is PAR.
You can use a SAD light early on in the seed growth phase, but you will need more red, bleu, and violet light for the following stage of growth.
