Growing duckweed

I've been raising duckweed for quite a while now, but with expanded projects, I'd really like to know how to get more out of this plant.

There's plenty of information on feeding duckweed to animals, people on youtube growing thick mats of them that are said to be constantly renewed, and a lot of recommendations for it on forums.

But so far I've found absolutely nothing on what to actually give the duckweed plants themselves. Especially for that much-repeated "doubling in less than 48 hours" thing they can apparently do.

I'm not expecting to get the ideal conditions for that exact result, but certainly more than what I'm getting now which is nowhere near that.

Does anybody know what fertilizer they like best? Comfrey tea? Fish water? Some sort of animal manure maybe?

Also, how often was it added to their water, and how large of an area were you growing the duckweed for that dilution ratio to work?

I tried several small experimental batches with different things last year, but didn't come up with anything conclusive. Thanks!
I will suppress my every urge. But not this shameless plug:
