I've been doing the exact thing you've been wanting to do for 3 years now Pipe Novelist. lol
Outside my apt I have two plastic tubs on the back porch that I filled with soil and planted whatever I wanted to see if it worked.
I've planted jalepeno peppers, serano peppers, cherry tomatoes, flowers, right now there's some cucumber growing by accident because when I'm not planting stuff I'll use them as mini compost piles and turn the soil every so often so all the organic matter and incorporate itself into the dirt.
I don't have any earthworms... which I've been thinking of, but there are plenty of ants and roly-polies everywhere lol
I don't take it too seriously so I let the bugs do what they may because it's where I smoke so it makes things interesting when I'm out there with a pipe watching the biodiversity interact with eachother.
While I was doing the compost thing and I turned the soil to see how well everything was breaking down I was expecting a horrible rotting smell, but I only through in fruits and veggies, and I was surprized by a very sweet smell. Not great, but definately not horrible.
Will post pics in a few min here.
