Its a very "stretchy" website because you don't have to buy his book, he gives you the plans and instructions. He gives suggestions on how to make your 12'x12' squares within the 4'x4' containers with things like recycled venetian blinds etc.
Its also "stretchy" because you get instructions on how many seeds to plant etc.
We were out running errands this past spring, and saw a sign for rototilers on sale...my husband started to turn in to check out the sale and then proceeded to have a broad grin because he remembered with container veggie gardens, no more rototiling! The rototiler we had was an ancient, stubbon hand-me-down. If we hadn't discovered the website, we were considering the $900 for a new one. Glad we didn't, I like the veggie container gardening philosophy.
We are having a wonderful strong summer rainshower right now. Now that we have a garden that I hand water using rainwater from our evestroughs, I never complain about the rain. 
I can't wait for my first beefsteak tomato sandwich. Yum.
