Unfortunately we live in a time where we need bars on our studio windows. However bars equals lots of hanging space for those weird tomato hanging planters as seen on TV.
We have tried using ground based pots but we have the cutest squirrel. I named him Rocky heĀ loves tomatoes, cute little rascal.
So we combined the two and now hopefully we will be overwhelmed in tomatoes this year. The super market ones are getting more and more tasteless every year

Container or bucket gardens are pretty easy to get started with.
I elected to go with a simple approach..For instance, I created an upside down bucket planter within 10 minutes.
It only cost be a $1.50 and is working nicely. You can take a look at my step by step pictures if interested.

Genius! I wish I had enough sun for tomatoes because indeed, the supermarket ones are terrible.
