title_body: How to grow coffee at home?
upvoted_answer: It is possible to grow coffee indoors. If allowed to grow as a tree they can reach 8 feet tall but if trimmed occasionally you can get the plant to grow more like a bush around 3-4 feet. This will change some based on the exact type.
  
  Coffee plants prefer shade with a couple hours of direct sunlight in the morning. Keeping it by a window should be about right. Depending on your climate you want to be careful taking it outside during winter.
  
  As J Musser mentioned, this will be a long process that will yield very little, but it can be done.
  
  On the plus side, coffee plants are evergreens and look very nice as indoor plants.

    One large apartment plant will only produce enough coffee for a few cups worth each year, and that's after years of growth. They do look good, though. My point was, indoor coffee plants aren't that effective. Outdoors, a good plant will produce around 2-3 lbs. of grean beans per year. They are usually planted about 8'x8' apart, or a near equivalent, so 680 plants per acre, = around 1700 lbs of green coffee per acre per year, under good conditions.
