VISIBLE LIGHT METER

 Plant Growth

• The red band of the photosynthetic radiation action spectrum (PAR).

• The light can be measured directly or the instrument can measure the light transmitted through a leaf, thereby providing a means to estimate the leaf's photosynthetic/phototropic pigment concentration.
