Warm growing orchids prefer the higher temperatures, light, and humidity that most closely relate to tropical and subtropical climates year-round. That means at night, the winter temperatures don’t drop below 64ᵒ F (17.7ᵒ C) and during any season during the day, they remain steady around 70ᵒ F to 90ᵒ F (21ᵒ C to 32ᵒ C) in sun. In their natural habitat, these orchids do see a slight temperature variation along with a diminished light, so we need to mimic those conditions when cultivating them indoors. Heating mats for orchids simulate these conditions and facilitate cultivating orchids in winter. Why would I need a heating pad for orchids? Bottom heat on orchids during the winter months is proven to be a necessity for warm-growing orchids and not just a luxury. The best way to provide heat for orchids year-round is with a heating pad for orchids. By increasing the moisture and evaporation after watering, a heating mat placed under the orchid’s pot will raise overall relative humidity (RH) in the environment. Seedling mats for orchids also induce root growth and supply perfect conditions for orchid seedlings to thrive until they are more mature plants.
