Which light makes the flowers grow the best?
I’m always amazed that people think sunlight is full spectrum light. Stars (our sun) each have a distinct spectrum of light that astronomers use for identification. In addition, a planets atmosphere will filter out various wavelengths. Finally the amount of atmosphere light travels through makes a big difference. Light is bluest at noon, on a mountain, at the equator. Light is reddest at sunrise or sunset, on a beach, near one of the poles. New technology can produce lighting superior to sunlight for plant growth but it’s expensive. As to the second part of your question, “other lights around the house”. A four foot shop light lamped with one cool white and one warm white bulb produce more usable light than expensive “grow lights”. CFs (compact fluorescent) are the new kid on the block and come in many different “flavors” of light. One, called ‘Sunlight’ by Lights of America, is a very good plant light.
