Low Light = two hours of in direct sunlight per day. Medium Light = four hours of indirect sunlight per day preferably either outside or by a moderately sunny windows or under lights would be suitable. High Light = six hours of indirect sunlight per day preferably in bright, sunny window or outdoors would be ideal for these plants.
How much light do orchids need indoors?
Here are some general guidelines:
For a brightly lit room with few windows – no more than six to eight hours per day
For a brightly lit room with one or two windows – eight to twelve hours per day
For a brightly lit room with many windows- sixteen to twenty four hours per day.
Unfortunately, placing an orchid across the room from a window, or in a room which faces north, is unlikely to provide sufficient sunlight. Depending on the genus, most orchids will suffer with anything more than 1-2 hours of direct sunlight per day.
Can too much light hurt orchids?
– If the foliage of the orchid plant is turning yellow or red, then it is a sign that they are receiving too much sunlight. Too much sunlight exposure causes harm and burns to the foliage. If the leaves are more yellowish, then it is time for you to shift your orchids to a more sun-protected area.
Is your orchid getting the light it needs?
Unlike many other house plants, orchid leaves should be light to medium green in color. Orchids with very dark green leaves are likely not receiving enough light and, as a result, may not bloom. Very light leaves with prominent yellow coloration, the result of too much light, may also be problematic.
The next thing we asked ourselves was; can orchids survive in low light?
While there are orchid varieties that can thrive even in low light conditions — the Paphiopedilum comes to mind — they don’t do well if deprived of sunlight. But they do well under artificial LED grow lights, however.
Yet another question we ran across in our research was “Can an orchid live without light?”.
Without sufficient light, your orchid may fail to bloom, and its leaves will change their color, usually going darker. Luckily, it’s not that difficult to meet orchid light requirements, especially if you don’t mind reaching for artificial lights when they’re needed.
