Colour of light
In photosynthetic plants the pigments are very important.

These pigments absorb some colours of
light and reflect others, for example, the green chlorophylls absorb
light from the blue-violet and the red regions of the visible spectrum

Part of light spectrum used in photosynthesis ..
Yet the red and blue parts of thelight spectrum are the most important energy sources for plants, and plantsrequire more rays from the red range than from the blue.
the effect of different parts of the light spectrum in photosynthesis
Until recently, fluorescent grow lights have had a low output and have been too big and bulky to be of much use as a grow light for anything more than starting seedlings. CFL and T5 full spectrum fluorescent lights have changed that. At 75 to 90 lumens per watt, these lights are energy efficient and extremely effective especially when used in numbers. Fluorescent grow lights also have better color rendering properties (more of the light emitted is used by the plant) and produce much less heat than incandescent and HID grow lights. This allows them to be placed closer to plants (within a few inches) greatly decreasing lumen loss from the bulb to the plant. It is recommended that these lights be placed no more than a couple feet from the plants for best results. 2700k to 3000k bulbs provide higher output in the red spectrum which promotes flowering. 5000k to 6500k bulbs are full spectrum with much of the light in the blue spectrum which promote overall green plant growth. ,
Through photosynthesis, plants use light ..
The standard T12 bulbs full spectrum tubes are fine for starts and seedlings and are popular for growing low-light plants like herbs and African violets. These lights are inefficient and are be replaced with high efficiency T5 lights which are a better light source for flowering and budding applications as well.
