Choosing
the right lamp for you:
Contrary
to popular belief, it is a well documented fact that the use
of smaller lamps for hydroponics/indoor growing is the most
effective and also the most efficient light source. The distance
between the light source and the plant is crucial. A slightly
higher number of smaller lamps close up is much more effective
than a lot of light far away. Use of larger lamps in this way
will only serve to scorch the tops of your beloved plants.
The
Inverse Square Law
The
most significant consideration in lighting is the 'Inverse Square
Law'. This law of physics says that the light energy available
is in inverse proportion to the distance it has travelled. Or,
put another way, if an object is twice as far from a light source,
it will receive a quarter as much light. If it is four times
away it will recieve a sixteenth as much light.
If
your plants are valuable you can't afford to economise.
