So a lot of times when I look at the culturing requirements for orchids, I see things such as "bright shade" "light shade" "bright sun", etc. My question is what do these things actually mean. For example, I grow my stuff in 10 gallon tanks right under T8 bulbs. In a setup like this can I even replicate these requirements? It seems since all the orchids are so relatively close to the bulb they would all be in "bright sun" or something similar. Here is a photo of one of the tanks to show you, I just want to be able to replicate these conditions for the benefit of the orchids.
