Yeah it is a common practice if you don't have room for a big garden. And there is lots of info here about it the search will pull up in addition to the discussions Rodney linked above. However in Texas it is weeks late to be trying to plant potatoes.

I know it's late, but you have to play the hand that's dealt. Instead of watermelon on the Fourth of July maybe we'll have some fresh potatoes. Yes, I was talking wooden boxes/bins.

It'll be interesting to see what yields you will have planting this late in the season. Tubers normally develop under short day lengths. And the best temps for the tubers to initiate are in the 60's (soil temp). I don;t think the plant itself would grow very well with prolonged temps (air) in the 80's and 90's. I'm not familiar with growing in boxes however. Hope it works out.

You could try planting for a fall crop once the hot weather breaks. On about the same latitude here and it works for me. Not as productive as spring planting but you still get some. What's you earliest frost date in N. Texas?

Anytime you grow potatoes in anything other than the ground they never get enough water. They need tons of water. they never produce as much as in the ground. Search the mother earth news article on testing different methods.
