This is wonderful, and I see how it is a great family affair. The little-peppers being put to work makes my heart sing as every hand needs to be used to make it work in a task like this. Makes me wish we had the land to be able to use a shipping container. Though, you mentioned once it outlives it's usefulness.

I have looked into many alternative options for shipping containers, and one of the most interesting ones I have found, is a year round hydroponics growing container, which could be powered by solar panels on the roof. The possibilities for these are endless, and I don't think you will run out of use for this puppy!
