Artificial Lighting
If you do not have a window that provides
sufficient natural sunlight, consider supplementing
with grow lights or completely going to artificial
lighting. One advantage of growing under lights is
that you are able to grow in any room in your house.
Complete light carts are available and come
equipped with lighting and humidity trays.
To receive the proper intensity, orchids will need
to be within 3-6 inches of regular florescent lights.
When using high intensity lights carefully follow the
manufacturer’s instructions regarding the proper
distance from your plants to prevent burning the
foliage. Most lights will also produce a certain
amount of heat so be sure to have good ventilation
and air movement.
In order for your orchid plants to flower
consistently, you will need to adjust your light
timers to replicate natural daylight. We suggest
increasing one hour each month from January (11
hrs) until June (16 hrs) then decreasing one hour
starting in July (15 hrs) until December (10 hrs).
The basement is an excellent choice for a
growing area because it will stay at a uniform
temperature and will have sufficient humidity.
Heavy duty plastic or reflective aluminum can be
used to insulate ceiling joists and curtain off an
area. By hanging florescent light fixtures over plant
tables and adding an oscillating fan for air
movement, you will have your very own subterranean
greenhouse.
