As part of my creation of a tropical growth room to grow some vanilla orchids, I was wondering if anybody knew the optimal conditions to grow this plant.

I would need:

  1. Humidity
  2. Temperature
  3. Watering levels
  4. Daylight hours

Thank you very much, Tropical.

On the care and requirements of Vanilla planfolia

  • Humidity: Over 50% is optimal. These plants thrive in very high humidity. However, steam is a little much. Try to keep it between 50 and 90% rh. 65-70% is ideal.

  • Temperature: Vanilla planfolia likes a daytime temperature of 80-85 degrees Fahrenheit, while at night, they prefer a temperature of 60-65 degrees Fahrenheit.

  • Watering levels: If the plant is in a potting medium, keep it moist at all times, if growing on a substrate, the plants roots and areal roots should be sprayed often, and never allowed to dry out. The leaves can occasionally be sprayed also.

  • Daylight hours: The plant requires 1500-3000 foot-candles all day, and in nature this will be 12-16 hours per day.
