Different types of orchids can be found growing everywhere from deep shade to full sun. The most commonly available orchids we grow at home need bright indirect light at a minimum, and in some case direct sunlight. We photographed this Brassvola orchid is growing in dappled sunlight along a riverbank in Belize.
Below are a few tips to keep in mind: 1  Temperature: Make sure the temperature isnât too hotâmost orchid blooms enjoy temperatures up to 75Â°F (24Â°C). 2  Lighting: Keep orchids out of direct sunlight, which can cause sunburn. 3  Humidity: Avoid overly humid conditions because rot can set in.
