Growing Duckweed

This is how we have had good luck with growing duckweed. You need good fresh nutrient rich water, oxygen, and sunlight. You can use aerator pumps and stones we are just trying to cut out as much cost as possible and are trying to run everything one 1 pump. You can also grow it separate from the system. We did it with the system to help with fish/water/plant ratio and we know that it is always getting everything it needs to grow without any extra steps.
