Depending on the wattage and type of the light, they are used as an alternative to the sun. Using grow lights can maximize the time your plants spend growing underneath them. Be careful, though, some plants do not like certain types of lighting and can be burned by them.
It is technically impossible to grow hydroponicly without grow lights.
it depends on the use
no it will not, you have to use "cool lights" or "flourecent lights"
With the use of fertilizer and grow lights.
high pressure sodium lights or led grow lights
You need grow lights which are in another light spectrum. Regular lights won't do as well to help your plants.
This is a good question. Garden grow lights are used when for indoor gardens that do not have access to natural sunlight. For a 5 X 5 garden you would need to use at least 3 grow lights.
yes i have purchased LED Grow lights and really these lights are too good.
green spectrum
You can, but it's not a great idea. Halogen lights, as with incandescent lights, use lots of electricity, and most of this generates heat rather than light.I would suggest using fluorescent, HID or LEDs for grow lighting.
Yes it is. You can use grow lamps on a plug in timer. Or you can now get LED grow lamps which use less power.
LEDs can be customized to emit only the light the plant uses for photosynthesis making it is a very efficient grow light. They also use very little electricity, create very little heat, and have a longer lifespan then other types of grow lights.
