"How much sunlight do my plants need?"
          Most orchids do not handle direct afternoon sun well.  Both the heat and UV (ultraviolet) rays are too strong.  The best conditions are morning sunlight or indirect afternoon sunlight.  Usually, a southern or eastern exposure will provide the light you are looking for.  Filtered sunlight using a screen or tinted window can also work.
          There are exceptions, Vandas can handle direct afternoon sunlight.  Vandas should do well in a West window that gets a lot of afternoon sun.
          Many customers ask us, "How many hours of sunlight do I need?".  That question is difficult to answer since we don't know the quality of your light or how much light your particular orchid might require.  With that disclaimer, we suggest at least 4 or 5 hours of bright light (not necessarily direct sunlight) to see decent plant growth.  More sunlight should increase the rate of growth.

What to do if your orchid gets too much or too little sun
          There are a couple of things you can do if your orchid plant is receiving either too much or too little sun. For too much sun, try is moving your plant a few inches away from the sunlight.  For too little sun, move your plant into a sunnier location.
          If this is not enough, you should probably try finding a different window or locationfor your orchid.  We have heard many happy stories from customers who found success by simply finding a new, better location to grow their orchid.
