Grow LightsProper lighting is the most important item in indoor
gardening. Adequate light is the key to photosynthesis. Without
adequate lighting, plants grow weakly, are leggy, and may even die. Our
eyes automatically adjust to varying light conditions, so what seems
like bright lighting can be useless for plant growth. Natural sunlight
is ideal for plant growth. For indoor gardening, it is up to the
gardener to supply proper lighting, in adequate quantities and with the
proper color spectrum, to replace that natural sunlight.
There are many
lighting, but the two most commonly used types of lighting include HID
Fluorescent Grow Lights -
grow lights produce just a fraction of the power of Metal Halide and
High Pressure Sodium grow lights, they are generally unsatisfactory for
general use. They are useful for starting new plants and for some
compact hydroponics projects, but must be placed very close to the
plants. To cover a 2′ by 4′ area, you will need a minimum of four 54-watt
4′ fluorescent bulbs, placed as close to the growing plants as possible.
Even then, results may not be satisfactory and producing fruits and
vegetables will be difficult. Still, fluorescent grow lights are well
suited for the very early stages of plant growth, and are often used to
start new plants.
High Intensity Discharge -
Both Metal Halide (MH) and High
Pressure Sodium (HPS) bulbs fall into this category. Their intensely
bright light makes them ideal for lighting indoor plantings. Both
require Reflector housings and Ballasts to operate. In almost all cases,
the same reflectors and switchable ballasts can be used to for both MN
and HPS bulbs. The area that these forms of lighting can cover depends
on their wattage. Ranging from 150 watts to 1000 watts, a single fixture
can cover from a small self-contained hydroponics garden up to 20-40 sq.
ft. Large installations will require multiple fixtures. Since HID lamps
create a great deal of heat, proper venting or even ducting and fans are
Metal Halide - These bulbs produce an intense light of
blue-white spectrum, excellent for vegetative plant growth. A plant
grown under a metal halide light will often exhibit increased leaf
growth and strong stem and branch development. They are less suited for
the flowering and fruiting stages of most plants
High Pressure Sodium - These lamps
produce an orange light, which simulates the autumn sun. This light is
best for fruiting and flowering flowers and fruit will be larger and
more prolific when these lights are used. Flowers and vegetables
finished off under high-pressure sodium will show tighter, stouter
blossoms with increased yields. High-pressure sodium lights are often
used in commercial greenhouses. If there is to be only one light source
for the entire life of a flowering plant, HPS is the best economical
choice. Many indoor and hydroponics gardeners switch between MH and HPS
bulbs, depending on the growth cycle. Almost all lighting systems we
carry support both types of HID bulbs.
Lights - Grow lights using efficient
LED sources are relatively new. Early versions of these lights had
insufficient power to be effective for most growers. Recently a new
high-density LED array technology was introduced, which packs more LEDs
and offers more power than previous LED Grow Lights.

Choose The Right
When choosing a light source the requirements of the
plant you are growing is important. Most vegetables, herbs and flowering
plants require high levels of light, while some tropical plants
including orchids and African violets will thrive at lower light levels.
Have Enough Light
The biggest mistake people make when
purchasing grow lights is not getting enough light. It is always
possible to reduce the level of light by moving the light farther away,
but its not possible to add light by moving the lamp closer, since the
coverage area decreases.
Maintain the Proper Distance
Fluorescent lights need to be 1 to 4 inches from the plants. High
intensity discharge lights should be 1 to 3 feet from the plant. And
make sure you change your bulbs on a regular basis. Fluorescent and HID
bulbs will last about 15,000 hours, but they lose 25%-35% of their
intensity after 4-6,000 hours. You eyes won't be able to see this loss
of light because they adjust, but your plants can feel it.
