The temperature and humidity requirements of these plants differ slightly, but the reality is, they can both live just fine within each other’s preferred growing environment. • Philodendron plants prefer temperatures that range between 70 and 80 degrees Fahrenheit with average household humidity levels. • Pothos plants prefer temperatures that range between 65 and 80 degrees Fahrenheit with humidity levels between 50% and 70%.   • It is an easy solution to provide extra heat and humidity for all your tropical plants by using either a Pebble tray or a Plant humidifier to provide extra humidity and a Plant Heat Mat to provide extra heat.
