I do a little of both , I have good luck with grow bags and tomatoes so I like to play with them. Nothing fancy, I either use 2x4s or 4x4 landscape timbers or even dirt to make a basin and lay the plastic sheeting over it . Last year I used an old wagon wheel rim and plastic and it worked good. Amazing how forgiving of a system it is, leave the garden hose that drips a little and walk away for a month. (Leaky hose ends are a dime a dozen) Larry Hall from Brainard is a well rounded guy from Worms to gardens I have learned a lot from his videos.
I ordered some of his recycled plastic grow bags, They were well made, This is the start of year 3 and they are fading but still holding up good. What I like about Larry is that he is not in it for the money. He sells grow bags but yet he will stand there and brag up a 50 cent walmart grow bag and tell you it works just as good. Lots of ways to garden and it doesn't take a very big area to feed a family.

Bugs me that he goes through all that work to use a rain gutter and those cups when a plastic drop cloth does the same thing and you set the bags right in the water, Look better too.
