Yep thats exactly the same stuff. Need 4 sets or 8 columns to provide the growing space I mentioned but you could easily start with just that.

My son from London is visiting me. He will be back next April and I showed him that set up and said he has to put that in when he comes in April (that pipe has to be stuck fairly deep in the ground and some part has to be exactly straight - better he do that than I do it). He laughed.

One reason he laughed is because he won a science fair when he was in high school and it was growing beans by hydroponics. As a result, he got to present that in the big show in Houston.
