Care - Temperature
Temperatures for growing orchids is different from temperatures for
The good news is most orchids do
not require the hot,
steamy weather found in the tropics.
They'll do just fine in the temperatures found
in most homes. So if you feel comfortable with the
temperatures in your home, your orchids probably will too.
orchids are comfortable in the same temperatures we live in
You can easliy tell whether a room is hot or cold by simply standing in
it. Understanding temperatures from a plant's perspective isn't quite
that simple however.
Temperature and Humdity
From a Plant's Point of View
Temperatures throughout a typical room can vary a lot. Most rooms
have areas that get more or less sun, more or less heat, and more or
than the rest of the room. This is
especially true near windows where
plants grow. These small spaces are called "micro-climates".
Conditions in micro-climates can
from the rest of the room.
For example, take a closer look at the micro-climate
near a window. When the weather outside
drops below freezing in the winter, the temperature next to the window
could be in the 40's. On a hot summer day, the temperature in that
spot can soar to over 100 degrees!
A good way to identify the temperature range in micro-climates
is with a "Hi/Lo Thermometor (also called a "maximum/minimum
thermometer). Our Hi/Lo Thermometors show the current
highest and lowest over time, and the relative humidity. I use
orchids grow in the same temperatures that we live in. Getting
them to bloom, however, means simulating the
big difference between
night temperatures they
experience growing outside in
least a 15-20 degree difference between day and
night temperatures to initate the flowering cycle. They
won't bloom without it.
Don't worry, you don't have set the thermostat for a 20 degree drop in
temperatures every night to get your orchids to bloom!
Understanding the micro-climates
in your home will solve the problem. Learn about the temperature range
your orchids are growing in by placing a Min/Max
themometer in your growing area.
You might be surprised!
Temperatures in a sunny window can reach 90
degrees (or more) during the day. In winter,
temperatures near that same window can drop into
the 50's at night. That's a 40
degree variation - perfect for orchids!
