Yep! I have a small setup with just some used food grade pickle buckets, and have been growing greens and things for a bit over a year. Going to get some more and expand them this year. It literally uses no power as pumps are not used, and water usage is very minimal. I live in the desert so low water usage is very important.
It's an interesting hobby, as you have to adapt it to the area you live, and where you grow the plants.
