Contrary to popular belief, orchids are easy to grow and maintain. There are some orchid gardening species that are definitely difficult to take care of but there are more species that can be tended to in the same way that you would care for a plant or a cactus.
The main concern in growing orchids is humidity. In the tropics, looking for humidity won't be a problem since the climate is generally humid. The western hemisphere, on the other hand, has less humidity. This is why, more often than not, you will only find orchids in a greenhouse or enclosed gardening structure.
You can cultivate an orchid inside your house as long s you maintain the correct temperature and correct humidity levels. The humidity problem can be solved by placing a water tray near the plant together with a humidifier.
As long as the humidity is maintained at a proper range, the orchids will thrive. Typically, orchids will need 40 to 70% humidity. Other orchid species will require more while some will require even less.
The amount of light that hits the orchid can also hold sway over its growth. Orchids grow in the wild as parasites clinging to trees. They are used to being under a forest canopy. Too much light such as direct sunlight will definitely make life harder for orchids. You can use black spots near the tips of the leaves as a signal that you orchid is receiving too much light.
Shading the orchid is very easy. However, putting the orchid near a window is really non-sensical. You already know that the orchid likes places with low lighting. Why put them near a window where light from outside shines inside?
Some species of orchids require more light. Using an incandescent bulb to provide extra light will help an indoor orchid flourish. Don't use heat lamps. Heat lamps have infrared that can burn the orchid.
When you're dealing with orchid gardening, avoid sunlight as much as you can. They like the shady areas better. Just remember that there are exceptions to the rule. Make sure to know your orchids' requirements as you buy them.
