You should keep the light at least 12 inches from your plants to help prevent burns. The average grow light does produce heat so you don't want it so close as to damage the plants leaves.
makes them grow. keep them as close as possible without burning them/ drying them out. Lights can be closer if plants are kept cool. ie fan or the natural temperature of say an unheated basement. If your only growing a few plants i'd use cfls. Constantly readjusting them can be annoying but you get far far far far far far far better results with the right combo of cfls. You can't have any other bulb for as cheap as they are as close to your plants giving them as much usable light than the cfl. Please try and prove this wrong i beg u
Arborvitae plants should be spaced about 3 to 6 feet apart when planting them.
Some plants can be planted close together and others must be farther apart. When you plant seeds, the package will tell you how far apart the plants should be. When you plant live plants, there should be a tag that tells you how far apart the plants should be.
chlorophyll pigment consists of antenna and reaction centres to absorb light energy.there are two regions in this pigment that is-pigment system I which absorbs far red light at 700nm and another is pigment system II which absorbs red light at 680nm.
it not because some plants are far away from the sun so they get less light if they get less light the day will be short
What has to be done is to judge the temperature of the heat emitted by the light bulb. This temperature should be adjusted by the distance from the bulb to the plant. As long as the leaves do not get hot and burn then this should be considered a proper distance. The key is not to damage the leaves.
You should plant them arond 3-4m apart
Tomato plants should be planted 36-60" apart from each other. If you plant them closer it increases the risk of disease.
Basil plants should be planted about 12 to 18 inches apart to ensure optimal growth and development.
Basil plants should be spaced about 12 to 18 inches apart in a garden for optimal growth and development.
Bougainvillea plants should be planted about 3 to 5 feet apart from each other to allow for proper growth and spacing.
Elderberry plants should be planted about 6-10 feet apart to ensure optimal growth and yield.
