A grow light is an electric light to help plants grow.Grow lights either attempt to provide a light spectrum similar to that of the sun

Or to provide a spectrum that is more tailored to the needs of the plants being cultivated.Outdoor conditions are mimicked with varying colour temperatures and spectral outputs from the grow light

As well as varying the intensity of the lamps.Depending on the type of plant being cultivated

And the photoperiod required by the plants

Specific ranges of spectrum

Luminous efficacy and color temperature are desirable for use with specific plants and time periods.

His middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart

And is sometimes characterized as heroic.During this time

He began to grow increasingly deaf.In his late period

He extended his innovations in musical form and expression.

The portraits of Vincent van Gogh (1853–1890) include

Portraits of him by other artists

And photographs—one of which is dubious—of the Dutch artist.Van Gogh's dozens of self-portraits were an important part of his œuvre as a painter.Most probably

Van Gogh's self-portraits are depicting the face as it appeared in the mirror he used to reproduce his face

I.e. his right side in the image is in reality the left side of his face.
