Like I said before in this thread, I finally found duckweed. But I don't have enough space to build a big earthen pond where I'll plant them. so I'm presently keeping them alive in a small basin until I can get sufficient space. I've also harvested some and dry them. I fed some to my broilers.

Some challenges to expect include algae growth and mosquito. Algae are those slimy green things you see on dirty water. You'll find them in gutters and stagnant waters. Some times the algae will try to outgrow the duckweed. I tackle this by either using a stick to get out excess algae or by changing the water. When you change water, wash the duckweed well and put them on the clean water. Add liquid fertilizer and lime to the water. This will help the duckweed to grow faster and cover the water surface - thus blocking sunlight from reaching the algae.
With mosquito, I've not found any solution yet. But I'm considering raising fish in another bowl next to the duckweed bowls. Hopefully, the fish will help cut down mosquito population not only in the duckweed pond, but in the area in general.

That is why it is always good to start everything small and learn. Thanks for sharing.

UPDATE: An effective way to control algae is by shading the duckweed from excessive sunlight. It seems to grow best under this condition.
As for mosquitoes, fish can't do a good job. Better leave it that way or cover with mosquito net. Or plant some lemon grass roung the duckweed pond.

.
Take pictures of it on your phone. Then go to areas close to streams, ponds and ask people if they have seen something like that. Also visit dry season farmers.

The soaking must be done in an open basin for enough oxygen to enter. Else, a toxic liquid will be the end result.

Never heard of duck weed before. Is it a good protein source?

Yes, I've watched videos where they grow it in hactares for carp fish. It can also be fed to pigs, chickens, goats etc. When dried, it contains 20-40% crude protein. The actual amount will depend on how well you fertilize it. You can read more about it here:
