What
size gardening area will a HID light cover?
|
Use the following
charts as a rough guideline for figuring out the area a light will cover
by itself, or when used to supplement natural sunlight. These figures
will vary slightly depending upon the reflector used.
Here is an explanation
of this chart.
Wattage- Wattage of the lighting system.
Appox. lumen output- This is the approximate lumen output of
the bulb when first used. Lumen output is a measure of how much light
is being produced by the bulb.
Garden area covered- This is the area the light will cover as
sole source of light for your indoor garden. You can support lush productive
growth inside of this area.
Garden area covered with sunlight- This is how much area the
light will cover as a supplemental source of light, i.e. in a greenhouse
or sunroom.
