Plants have photoreceptors that can trigger different growth characteristics when activated by photons of specific wavelengths. So by controlling your light spectrum you can affect powerful changes in plant growth. Growth characteristics that can be affected using spectrum are listed below:
> Fruiting
> Flowering yield
> Rate of growth
> Fresh weight
> Compactness
> Root development
> Plant health
> Color
> Flavor
> Nutrition
It’s important to note that activating plant response using light spectrum is one component of a larger process and results are heavily dependent on many factors such as light intensity, photoperiod, growth environment, plant species, and even plant variety.
