Plant canopy penetration & reflection demo | Does green light or Far Red light penetrate the leaves?

I demonstrate the amount of light passing through leaves and being reflected by them.

Green and yellow wavelengths pass through the leaves and are then absorbed by leaves lower down.
Green and yellow wavelengths are also reflected but it is only a small amount.
Far Red is more likely to pass through the leaves and be absorbed lower down or be reflected upwards and lost.

Sensor/spectroradiometer used: Asensetek Passport


Grow light used: MIGRO 4000K CMH
