This is an awesome idea!
I don't think that I have the space for this but I will definitely remember this for any time I need to do something similar. I have some stuff about my own home vegetable/herb gardening in one of my Journal posts.
Remember to post something when you start planting!
It is really amazing what people are doing with pallets...
Maybe you could try vertical pallet gardening like this one...
That's really cool. I can go for that.
