LIGHT EXPOSURE - The luminosity is an important factor in the health of the orchids, but they usually do not tolerate direct exposition to the sun. In general, orchids do well in half-shadow: under trees, under wooden stripes or even in varandas or window of an apartment where direct sun does not happen.

The first step for giving the exact amount of light for your plant is to identify the species or genus. Then you may choose the best place for putting it.

The amount of light that each species need differs from plant to plant. Dendrobium, for instance , likes some 60% of light and even some weak sun on the first morning hours. Others, like Paphiopedilum, Miltonia Colombiana and several micro-orchids can not stand high temperatures and sunlight, therefore should always be on shade conditions.

Orchids may grow on shadow, half-shadow, strong sun-light and full sun exposure (some). Should have bright green, healthy leaves. Dark green leaves indicate that a plant is getting insufficient light, and yellowish-green or red leaves indicate that a plant is getting too much light.

Placing them outside under the shade of tall trees during the summer months is very beneficial.

Depending on the orchid species, they can be grown in shade or half shade or can get plenty of light but, even though there are a few exceptions. Usually they should not receive direct sunlight except for the the first sun rays in the morning.
