I would enjoy viewing that case study.
For myself, this would be great, as I use small hydro bubblers with expanded clay (earthright) substrate, in hexigon containers for my families herbs, such as cilantro. Even lettuce does very well, I've done chilli's as well. So this device could very well suit my situation.
Using fish oil in the house is never a good idea, however if you have dozens of feeders swimming around down there, that I'm interested in. And it looks nice as well.
