ARTIFICIAL LIGHT - Illumination that comes from a man-made source, such as electronic flash.
Artificial lighting is crucial for successful indoor gardening, but not just any indoor garden lights will do. Inadequate lighting will result in tall spindly plants, yellowing leaves and failure to bloom or set fruit.
Artificial Light
Usually, natural sunlight is used for this important job. However, during the shorter and darker days of winter, many growers use artificial lights to increase the intensity of light (for ) or to expand the daylight length.
artificial light should also be supplemented.

Using fans and artificial light, you can create a hospitable plant environment in a piece of furniture-an idea that dates back to Victorian times, as witnessed by the archival illustration at right.

You can dictate many of your plants functions by giving them supplemental artificial light. There are 'grow lights' on the market today that successfully imitate natural sun.
If artificial lights are to be used as the only source of light for growing plants, the quality of light (wavelength) must be considered. For photosynthesis, plants require mostly blues and reds but for flowering, infrared light is also needed.
How to Grow Houseplants in Artificial Light
If you're trying to grow houseplants indoors, you'll find that some rooms of your house are low in natural light.
Another problem with container plants of all sizes is that they've been overstimulated by artificial light, too much fertilizer or a combination of the two.

"You must have a well lit window or use artificial light to keep indoor gardens alive," says Gretchen Lindgren, owner of Gardens by Gretchen in St. Cloud, Minn.
When using artificial lighting, attempt to simulate daylight by giving plants regular periods of light and dark. Most plants do best with 12-16 hours of light per day.
If you do not have a south-facing window, you will need to use artificial lights. When growing seedlings under lights, you can use a combination of cool and warm fluorescents, or full-spectrum fluorescent bulbs.
The sun or artificial lights provide the light plants need. Moisture comes from rain or you watering them. Fertilizer can come from compost, manure or commercial fertilizer.
If you don't have a greenhouse, you can still grow good transplants with artificial lights. Before we got a greenhouse, we grew thousands of transplants every year in a space no bigger than a refrigerator.
Incandescent is the most common and least expensive form of artificial light you can use as plant grow lights. It is also the least efficient in terms of converting electricity to light and the poorest source of light for plants.
Although they will grow under artificial light they do best with natural light. A sunny kitchen or entrance area is a good spot to place the Flamingo flower.
Place plants near windows during the day or install artificial lights. Ordinary light bulbs give off too much heat and may scorch foliage, instead use cool white or daylight strip lighting and position the lights at least 45cm for the plants.
You want to balance artificial light with natural light. Take note of where natural light is prevalent in your room and where you may need ambient light, task lighting and even accent lighting.
This may seem extreme, but artificial light and even the low rays of the winter sun are not as intense as full summer sun.
Wilting, lifeless: pot too small, needs cooler location, more sun or artificial light.
Not producing blooms: try more sun, keep evenly moist, reduce fertilizer.
Once they've germinated, place them under a grow light or in a sunny, south-facing window and provide extra artificial light in the evening (they need 14 hours of light per day).
No need to use artificial light with plenty of black dripping candles (used with adult supervision) and a variety of jack-o-lanterns. Black streamers can also be useful on the floors and walls to transform your cheery home into a dreary dungeon.
Plant chrysanthemums in full sun. Do not plant mums near street or night lights as the artificial lighting will disturb their photoperiod cycle. Do not overcrowd chrysanthemums -- good air circulation helps prevent disease.
Willdampier formosa, Sturt's Dessert Pea, have also been raised in readiness for the show. They have been grown under artificial light designed to mimic inland conditions, and will flower in October, four months before they usually do.
If your home does not receive a lot of natural light, consider incorporating artificial light, such as fluorescent lamps to aid in your plants growth.

Growing asparagus indoors successfully will be a matter light. A sunroom, a good skylight, artificial light, or some combination of those assets will be required.
You also can start zinnias from seed indoors, planting them in flats or a seed starting medium 4 to 6 weeks before the last expected frost date. Keep them under artificial lights at a temperature between 75 and 80 degrees Fahrenheit.
The plants like lots of sunshine. Place them in a sunny window, but avoid hot rays coming in during summer months. Provide artificial lighting if little sunshine is available.
Artificial lights confuse the insect response, since these lights are so close (an unnatural situation). Trying to maintain the flight angle to these close light sources cause the insects to spiral to the source.
Choose a spot in your house that you want to dedicate to growing herbs. If you have access to sunlight, chose the spot near a window, if not you can always use artificial lighting.
