My apartment doesn't have a big enough deck to utilize my full size garden barrel, so I designed a miniature version for herbs. The base of the barrel collects excess water that can be reused to water the garden. The little side pockets are a great way to seperate your different herbs. The pot design is also stack-able if you wanted to do that. If gardening is really your thing then you may also like the full sized 30 gallon barrel version seen here: http://www.instructables.com/id/Barrel-Gardens-Big-Value-in-a-Small-Package/
