Same thing, different brand names, both work on the same principle.
I have found them to be excellent for growing, just don't skimp on size, 10-15 litres for autos and 20-35 litres (or bigger) for photoperiod plants.
They certainly do what they claim, once you empty them after harvest, you will be amazed by the root structure.
Looked after, cared for and washed between grows, they will last for years, making them quite economical in the long run.
Hope this helps,......
