Temperature: Being a tropical crop minimum temperature is 15o C to 17o C and maximum temperature is 32o C to 35o C. For good quality flowers and production fluctuation in low and high temperature is detrimental. However if relative humidity is maintained then most of the problems are avoided.
Humidity: This is an important factor for growing Anthuriums 65 to 85% humidity is ideal for quality and production of flowers. In greenhouses / shade houses fogging system or misters would be ideal. For open cultivation the surrounding area can be sprayed to maintain required humidity in addition to use of gravel/coconut husk etc.
Sunlight: Anthurium is a shade loving plant it requires 75% shade. Too much light/sun causes the flower to fade and the leaves show signs of scorching or burning effect.
