Yes, I understand! There is quite a bit of literature on duckweed. I have several duckweed (different species) experiments going right now. Nothing fancy, I am playing with many variables that affect their plant growth (things not touched on by available literature). For instance, recent studies have starting delving into the microbial ecology interacting with duckweed that affect the growth. Because this is such a niche area of science, they are areas lacking research with agricultural applications.

Back to the farm use, duckweed grows and can grow to the established rates of growth in the literature. People have been growing it for use in commercial applications for decades worldwide. It feels like we're beating a dead horse at this point...

How deep down the rabbit hole do you want to go?
