Red and Blue light are best for plant growth because those two wavelengths are what chlorophyll respond to.
.............if this is tru y not use a black light................it emits purple light
Plants are effectively able to use Violet/ Blue light between 400 and 475 nanometers (wavelength) and Red light between 650 and 700 nanometers (wavelength) - which are absorbed by chlorophyll a and chlorophyll b.
Green light which falls within the 475 to 650 nanometers wavelength, is not used as much as chlorophyll is green in colour and reflects these wavelengths. However, Carotenoids are a group of accessory pigments which occur in all photosynthetic organisms. They contain about forty carbon atoms, often without oxygen atoms and are fat soluble. They are chemically unrelated to chlorophyll and consist of rings connected by long chains of carbon atoms. They absorb light maximally at wavelengths between 460 and 550 nm and are therefore yellow, red or orange in colour as they reflect the wavelengths in this part of the spectrum. Carotenoids are found in all photosynthetic organisms.
The 'blue' wavelength is essential for vegetative growth, and the 'red' wavelength is crucial for flowering/bud growth.
blue - violet light should be used. Violet light is near the end of the visible light spectrum because it has a very low wavelength.
Most of the visible light spectrum except green wavelengths is absorbed by the chlorophyll molecule and is usable in photosynthesis as a source of energy for plants.
Not every plant wants the same color of light. Red and blue light are the most commonly used. The sun gives off a rainbow of colors.
red/orange and violet
every thing except green
It is the most fertile
The three places that growth takes place on a plant is a certain temperature, water, and oxygen.
According to what I have researched most light can make a plant grow, it just depends on the wavelength that the light is flowing. Carl Gelenye has done some work with different wave lengths of light for plants growth and found the violet works the best and blue is the worst.
nitrogen
Gibberellins are growth hormones that control plant height and bud development.
That depends on the composition of the "poop". Poop from ruminant animals could be quite beneficial to plants. -Poop from most humans will not be so good.

Most times, yes

PGPR (= Plant Growth Promoting Rhizobaceria) In the rhizosphere, that is on the plant root or its close vicinity, bacteria are abundantly present, most often organized in microcolonies. Some of these rhizobacteria not only benefit from the nutrients secreted by the plant root but also beneficially influence the plant in a direct or indirect way, resulting in a stimulation of its growth. These plantgrowth- promoting rhizobacteria (PGPRs) can be classified according to their beneficial effects. For instance, biofertilizers can fix nitrogen, which can subsequently be used by the plant, thereby improving plant growth when the amount of nitrogen in the soil is limiting. Phytostimulators can directly promote the growth of plants, usually by the production of hormones. Biocontrol agents are able to protect plants from infection by phyto-pathogenic organisms.
