I want to correct something i said i oversimplified. You can grow more than herbs and greens in a 4-6" grow bed. Tomatoes and peppers, squash, broccoli, cucumbers, watermellons.. For some of these things you may need to train them or setup trellis but you could grow anything really. It's just might be a little more to consider. Plus, generally more biofiltration the better.
Yah, rubbermaid tubs can work. I have seen people use those cement mixing tubs. they are shallow but like you say, it's temporary. you could even use the 110 galoon stock tank as a grow bed.
