The number of hours of light exposure and the intensity and quality of the light have a major impact on a plants growth and overall healthAdequate lighting is also critical in triggering the flowering process. For cool temperature orchids the night temperature should not drop below 45 degrees Fahrenheit and the highest temperature in the daytime should not exceed 70 degrees Fahrenheit.
Forty degrees is the low end of their temperature range.
Lowest temperature for orchids. Orchids are usually classified as either cool- intermediate- or warm-growing depending on their temperature needs and the usual definitions of these ranges are. Warm 80-90F days and 65-70F nights Intermediate 70-80F days and 55-65F nights and Cool 60-70F days and 50-55F nights. Cool orchids tolerate temperature of 50ºF 10ºC during winter.
During the summer the maximum should be 75ºF 24ºF. Intermediate orchids prefer 55º to 86ºF 13º to 30º C. Warm growing orchids range from 64º to 90º F 18º to 32º C.
The lowest temperature that cattleyas can stand is at times down to 32 degF. At others injury occurs at 37 to 38 degF. Flowers may discolor below 45 degF.
Some growers claim virus-free flowers will stand 40 degF or 41 degF. Cool temperature orchids include Cymbidium Dendrobium and Odontoglossum. For cool temperature orchids the night temperature should not drop below 45 degrees Fahrenheit and the highest temperature in the daytime should not exceed 70 degrees Fahrenheit.
Generally temperatures between 50 and 80 F 10 to 27 C are ideal for orchids. But occasional brief periods of temperatures above 100 F 38 C or drops even into the 30s 0 C will not harm most orchids as long as no frost forms on the leaves. Cold injury includes damage from temperatures above and below freezing.

Temperature Protection Orchids prefer daytime temperatures of 75 F or more and nighttime temperatures of 65 F or more. In winter time this is not always practical to achieve temperatures quite this warm. However efforts need to be made to not allow blooming orchids to be exposed to temperatures significantly colder than this.
Zygopetalum orchids grow well in moderate temperatures. The optimal day temperature is between 70F and 75F and it should be about 10F lower during the night. However you should always check what particular species you have.
Those that grow at higher altitudes such as Zygopetalum Maculatum and Zygopetalum Intermedium prefer cooler temperatures. Forty degrees is the low end of their temperature range. Although orchids do like it a little cooler at night just like people do.
Orchids do best when nighttime temperatures drop at least 10 degrees. This temperature fluctuation is necessary for orchids to bloom. Without a day-night fluctuation of 10-15 degrees Fahrenheit the plants will grow plenty of healthy foliage but may stubbornly refuse to flower.
A night temperature of 60-62 degrees F is ideal for optimum growth but temperatures as low as 55 degrees F will not harm your plant. Temperature humidity and watering frequency are all key to having a healthy orchid. However light is probably the most important variable.
The number of hours of light exposure and the intensity and quality of the light have a major impact on a plants growth and overall healthAdequate lighting is also critical in triggering the flowering process. Though most orchids typically prefer temperatures between 50 degrees and 80 degrees Fahrenheit many orchids tolerate temperatures up to 100 degrees and down to 30 degrees Fahrenheit. Daynight temperature differential is key to blooming.
When your Phalaenopsis orchid starts sending up a new shoot place your orchid where nighttime temperatures will be slightly lower than normal ideally 55 to 65 degrees F. Exposing your Phalaenopsis orchid to cooler temperatures for about a month will encourage it to flower. Orchids are often categorized intogeneral temperature groups that are based on the preferred winter night temperaturebelow which growth slows.
The three temperature groups are the warm growers with nights from 60 to 65oF the intermediate growers with nights from 55 to 60oF and the cool growers with nights from 50 to 55oF. There are three temperature zones for orchids and each type of orchid has an ideal temperature zone. Warm growersneed daytime temperatures approximately 70- 85F 20- 30C.
Enjoy a slight temperature drop at night but should not go below 65F. Maintain a temperature of 6075 F 1624 C in your home. Orchids thrive in moderate temperatures and will die if they get too cold.
Though the correct temperature varies based on the species of orchid.
