The benefits of Duckweed/ or lack of benefits???.

[Agroregeneration]

I have read through this thread, and maybe this sounds dumb, but what is wrong with setting up a $3 plastic kid pond that I can buy at walmart and adding some water and duckweed, in a space of 3x3? Every 2 days, I scoop out some duckweed and supplement the diet of the fish. If I bought commercial feed, even $1 or $2 worth, I have to actually come up with $2. This way, I just scoop it up, plop it in, and come back in 2 days for some more. I don't mean it as a miracle food, but simply to lower my over all cost of feeding my growing fish. How does this not make sense to do?

Exactly what I do with duckweed. But I have about 50 square feet of surface area I grow it on.

You use the BSFL effluent correct? I sent you a message about that if you wouldn't mind checking your in box.
