Inside plastic vs- Outside plastic

So, you need a container to grow your plant in.  The solution seems simple enough but before you start filling plastic containers with dirt consider what you are doing.  

A few years ago I filed a plastic tote with soil and placed wheels on the botom.  Thus, makeing a moveable planter.

It was a good idea...for the first few years.  Then the weight of the dirt started to push the sides of the tote, and it looked like the tote was wearing a pool float around its middle.

Then the edges of the tote started to become brittle and chip away.  So in the long run you can help prevent a potential mess by using plastic that has been UV (ultra violet sun protection)  Or you could try to rub sunscreen on the bowls that will be outside.
