I would like to find out what you think "indirect light" means. Be as specific as possible.

1 Indirect Light:
A better discription would be "second hand" light. A brightly lit area where light that has come into the room, but not directly in a path from the sun. Bounced of a wall for instance.

2. Low Light:
Light from a southern facing window, or a ways away from any reflected light.

3.Diffused Light:
Light that has been filtered by some source. Blinds or tree branches for example
Low light or shade:
A area where you would want to turn on a light to read.

4. No light, (as in what Christmas Cactus needs to flower):
Means absolutly total darkness for what ever specified amount of time. Light from a street light down the block could be enough light to keep certain plants from blooming. Perhaps tucked away in a closet, or under a black painted box.

5. Full or direct Light:
An area that can cast a shadow for more the 3 hours a day, the rest of the day being in at least indirect light.

6.Partial shade:
An area that recieves less then 3 hours of morning or evening light (No noon day direct sun) Most plants the require partial shade will do well in difused or filtered light as well.

Hope this helps

For those of you who are interested, I have written a short article on light for indoor plants. It includes comprehensive descriptions of direct light, indirect light, low light, et. al. that I hope takes some of the confusion out of these terms.
