Plants & Light
Controlling the light quality and knowing which part of
Light is electromagnetic radiation transmitted as
photons. In plants light is absorbed by pigments and
photoreceptors. Plants use light for photosynthesis
in a reaction chain, in which light energy is
converted into chemical energy. Light is also
conveying information to the plant about its growth
environment.
the spectrum and which combinations of the spectrum
areas are involved in different processes enables plant
growth steering and production of plants with desired
characteristics i.e. germination, flower induction, stem,
elongation etc. Single peaks of light do not grow plants
in the optimal way and energy is wasted on boosting
micromoles in the peaks. When the light conditions
are optimal throughout the breeding cycle, the cycle
can be shortened dramatically together with improved
quality of plants in each step of the way.
