Well, u need to remember where ur orchids come from. If they r florida
natives then it's allright to remove the cloth. But if they grow in tropical
rainforests, do those tropicals shed their leaves?



A couple of things to keep in mind:

In the tropics, light intensity is usually higher in the dry season
due to less cloud cover/precipitation. When growing orchids in more
temperate climates the dry season usually corresponds to winter.

As we go further away from the equator the light intensity between
summer and winter varies due to the angle of the sun. Therefore, you
need to give them more light in winter than in summer.

Low light orchids will probably be fine in a evergreen tree but those
which need more light are likely to flower better on a deciduous host.
