Here is how I made a upside down or topsy turvy planter for tomatoes or strawberries from a 50 cent Wal-Mart bag. I have not seen anyone else do this , however, I got the idea of using Wal-Mart bags as planters or grow bags from Larry hall.
Larry has a great garden channel, if you subscribe to him, tell him I sent you.
The bag is super easy to make, just cut a hole big enough to pass the plant through and use thin soft packing foam sheets cut into 2 circles to cover the hole for the plant to keep the dirt inside the bag.
The open weave of the bag seems to make plants grow better than in a plain solid container as the roots get more air.
I have had a lot of luck making my own grow bags from landscape cloth and actual dirt bags by poking hundreds of small holes as seen in my videos.
