LIGHT BANDS
Light can be separated into a spectrum, which form the colors
of the rainbow. Red, Orange, Yellow, Green, Blue, Indigo, Violet.
Each of these lights mix down to give white light. Artificial lights,
because of their nature, tend to lean towards a tint of one of these
colors when they mix down to form white light.
The electro-magnetic spectrum is a term used in lighting to
123
describe the distribution of electro-magnetic radiation by reference to
energy. This Cause And Effects Smoking Granddaddy Spice table roughly gives wavelengths, frequencies and energies
for parts of the spectrum.
There is also the color part of the spectrum
that is very important for plants.
Plants are green, which means that Plants absorb light at the
middle of the spectrum (Orange to Indigo). Cannabis plants need this
part of the light spectrum to reach full growing potential. The intensity
of the light is also important. A light that feeds the full bandwidth with
all light spectrums will work very well - like sunlight. When dealing
with artificial lights it is better to choose a light that concentrates its
intensity on the top part of the spectrum. The most common indoor
light systems are called HID lights. We will discuss the full range of
lights that you may come across in some grow rooms.

POOR LIGHTING SYSTEMS
Domestic Lights:
Figure 5.6 oaksterdam clones for sale - A domestic bulb. Also called
an incandescent light source.
These are the lights you find in use around your house. These
lights come in all sizes and wattage - 15 watts to 150 watt. These
lights are not suitable for growing because of their low light intensity
and bad color spectrum.

AVERAGE LIGHTING SYSTEMS
Fluorescent Tube Lights:
Figure 5.7 and 5.8 - These are examples of some fluro fixtures and
bulbs that can be bought in most hardware stores.

These lights are the long industrial lights that are found in
many a school and work place. These lights come in nearly all lengths
and sizes. 2 to 10 feet are the main sizes that are out there. They also
run between 10 watts and 300 watts. These lights are okay for growing
but they provide little light and are hard oaksterdam clones for sale to set up properly. They also
are not in best light spectrum for Cannabis plants to grow in.
Halogen Lights:
Figure 5.9 - A Halogen light.
Halogen lights are the small lights that can be seen on the
outside of factories for flood lighting the grounds during the night.
They are usually small and black. These lights can range anywhere
127
between 75watts and 4000watts.
Halogens get extremely hot and can provide an unsuitable
condition for growing Cannabis under. They are not recommended
because they are dangerous to use indoors for growing. They are also
not in the best light spectrum for growing Cannabis.
Fluorescent White Tube Lights:
These are not in use much and are very similar to the
Fluorescent lights except they are in the correct growing spectrum.
These lights are not very strong and do not range much above
100w
