- How Fast Does Duckweed Grow? I put it to the test in this video we test how long it takes before the duckweed takes over a Aquaponics grow bed.
For those of you who don't know what duckweed is, it is a small floating plant that grows on still ponds. It can cover an area rapidly and because of this can cause problems. Now however, duckweed is being touted as a miracle plant for many reasons including the following:
•Cost effective renewable energy, biofuel
•Water filter
•Mosquito prevention
•Prevents algae growth
•Reduces evaporation on bodies of water
•Virtually free animal feed
•Food for humans
Duckweed as a Water Filter
Duckweed loves muck. It can clean the water from farms which are rearing cows, hogs, chickens etc. The run-off from these farms can cause an ecological nightmare if left untreated and allowed to leech down into the water table. Duckweed can clean this water by absorbing the resulting chemicals.
In Palestine, they are looking at using duckweed to clean their water systems as they have very limited fresh water available. Using this natural low cost water treatment is not only good for the country but the environment as well.
Control of Mosquitoes
Mosquitoes love shallow still pools of water to lay their eggs in. This is a major problem in many countries, not just third world countries. Duckweed could be the solution.
Because duckweed covers the surface like a thick blanket, it blocks the mosquito from laying eggs. Malaria, dengue fever, and the Zika virus are three of the diseases spread by mosquitoes here in Brazil and other parts of the world.
Stop mosquitoes breeding and you drastically reduce the number of illnesses and deaths attributed to them.
Duckweed as Tilapia Food
A massive savings when you are feeding several thousand fish.
We are growing the duckweed to use as a supplemental feed for the fish. The high protein content of it makes this an ideal food for them
It isn't just fish that eat duckweed though. When fed to chickens they produce more white meat.

I got two leaves of duck weed accidentally from Petco with my guppies!!
I didn’t know what they were but I left them in the tank anyway, 10 weeks later, now my 20 gallon tank is completely covered with duckweed!!! There are thousands of them and they look awesome!
"All you need is a Table Spoon sized amount"
Adds a Net full
All you need is one pieces
actually you only need 1. first came in contact with duckweed years ago when it was just a pest. and if you left 1 piece in your tank it took over. Now we have chooks and i dont mind
It really was it compacts lol
four weeks, and it's turned into a little jungle! Impressive stuff, TFS
We are going to try to make a feed for our other animals also
En qué clima se produce
Grows fast...but that was way more than a tea spoon that started it.
teamhex it was about a table spoon not much more than that Thanks
goforgreenliving do you know what a table spoon is? Mate that was a lot
Mmmh mmh that was at least 2 & 1/2 tablespoons
A spoon the size of a small table.
That was a table spoon for a Giant 😂
Gives a whole new meaning to "duck and cover" 😉
Lol your right my friend
awesome video... thank you for sharing. hope you continue to make videos like this..cheers!
Wow... Faster than I thought... We have some wild sources... Might have to try this... Thanks for sharing !
Its one of those wow plants that we grow its worth a try!
What kinda tea spoon is that, that was like half a cup lol, call that a county tea spoon
Lol it spreads out alot
If I made it inside the house
How much plant needs an hour in light
!!
What is the appropriate climate for its growth?
Great fella
I've never heard of duckweed. Amazing how fast that grows! I wonder what it would do to our pond? We did get some grass carp a couple of months ago so I guess they could control it if it got out of hand.
I'm sure it will work duckweed will benefit your pond in many different way's Thank you for watching
carp will eat it all. need a base grower to grow it and put it in pond. great for fish
Great video, thank you for posting; Do you use a greenhouse or have any issues with mosquitoes?
During the dog days of summer they are every where but the rest of the year its fine Thank you
The more nutrients the fast it grows. It's why it takes over ponds blindingly fast because the sediment is likely highly nutritional, and fish poo is very good.
Got to be careful on a pond though, it can get so tight it stops the water oxygenating and boom, you have a stagnant bowl of water. If you have plants in the pond, they can die from lack of light and then the last source of oxygenation is gone so your fish won't last much long after.
Some of the stuff made it into my fish tank, it murdered my floating lettuces in short order. But it can't full take over as I have a agitation filter. So I just let the little patches of it go.
Lol that was big table spoon thanks for the vid bud
It was about right believe it or not it takes a lot to make a table spoon
Thanks!
Hey no problem thanks for stopping by. Do you know how much duckweed I have now lol things change but my fish and chickens enjoy it so much I grow plenty
@@goforgreenliving so awesome
A creek near me has this stuff and I didn't see it larger in diameter than a basketball so this is surprising. I'm glad I didn't put it in my aquarium
its great for aquariums! =D
I am really into water in any way or form. So thank you for putting up this video my friend.
GOD'S LOVE and JOY.
Its easy to grow and helps the water
It was nearly half full to start with with that teaspoonful you put in haha.
No they spread their wings in the water. It was the right amount lol
Fantastico video 📹 😍
“I’ll just have one shot”
*downs whole bottle* 😭😂😭
Lol it looked like alot but it wasn't
trying my hand at growing duckweed...some of mine is turning white and im not sure why
Thats a lot of duckweed :)
And it is still growing lol
Is fish waste enough to supply this with nutrients in a aquarium setting?
nice my koi fish will love them he he
I bet they will
Hello i wanna ask you a question. if i am right you use the aquaponic water to grow duckweed but the duckweed will be use ammonia instead of your grow bed plats .??
It mostly likes the solid waste more that the ammonia
you should have added a bunch of leaves, twigs and other natural stuff in the tank first. We grow duckweed in a pond and it grows much faster than that. We found out it is because of all the leaves and stuff like that in the bottom of the pond.
Our pond is about 100' by 50' and it just keeps full of duckweed with all the leaves to feed on.
What area do you live?
@@understandinghis-story8205 We live near Charleston, SC.
I grow to much lol
What kind of Fertilizers are best for more duck weed and faster production,Animal waste or Poultry waste or Chemicals Fertilizer
Duck weed does nothing to stop mesquitos here. I put minnons in with the duck weed. The mesquito larva have no problem growing in the duck weed, and the minnons easily can find and eat them. What is the best water temps for Duck weed here in Arizona the water temp is 81 F. My duck weed lives but I'm not seeing those results. My Duck weed seems to clump together and sink to the bottom of the pond. I've reduced the movement of the water since then , and the 18' pool has a small airpump in on one sdie. I've added a fertilizer in small quanities to the pool. It only has one cat fish in it now. It's summer time here 105F is normal I won't order any fish until December when it cools off!
I've got the pool under 60% shade cloth, as the garden would burn to a crisp in this area without it.
Troy Brownrigg are duckweed is so tight together the mosquitoes can't find the water I mean I see all kinds of other insects walking on top spiders rolly pollies and in all kinds so once it thickens up I don't think they can get in thanks for the input
put guppies in it ........
I'm in Arizona too, looking into starting this, thanks for your input
Very cool!
Thanks
Chuck
Do you have any growing in your awesome system?
not yet. I will once I complete the fish house build.
Thanks Daniel!
Chuck
Was that a giants teaspoonful?
It really wasn't its spreads one it hit water
Thanks for the video. I would like to buy a teaspoon of cocaine from you, it should last me a long time, lol. Just kidding I don’t do cocaine.
It took me several times reading it I finally got the joke, everyone says it was alot but it was about right a good heaping tablespoon. It produced one heaping gallon jar in one month. How's that?
@@goforgreenliving that’s great! Do you feed it to animals? Do they like it? Thanks
Yes my chickens love it I leave it out for them baby chicks run for it.
@@goforgreenliving thanks!
How fast it multiply?
Let's say if I start with 1 kg of duckweed, when it would grow to 2 kg?
Thanks
In the right conditions 2 weeks doubled in 4
Where does the tub sit? in sun or shade?
Steve Finestone it's in full sun
Ty
Your very welcome
Do you eat your duck weed?
Nofretari I have eaten small amounts several times 😀
Does it ever get to the point that you must 'thin it out'?
We use it so much but sometimes I do throw some in the compost
nice
Thank you
wow never heard of duck weed before..what is it good for?
Lots of stuff but mainly I feed it to my fish its very good for them
tons of stuff, keeps pond water from evaporating too, good for water quality, good for water temps, ect ect
Sure would learn more if I could hear you over the music
Sorry it gets better
Did you plagiarize your description
Or did I not just not see the credits or something
I must’ve plagiarized the first person to search “How fast does duckweed grow”
I apologize to whoever the first person to ever ask this question is, for stealing a thought 💭
You are a very smart man if I don't say so myself!
Wasnt a teaspoon but nicee
Do you add something to the water?
No it produces what it needs
i have duckweed sitting in my aquarium for 3 weeks and it just doesnt multiplly ...
I'm not sure why it's not maybe something is eating it
i am bangladeshi
i cutivate duckweed.
please help me?
you say what can i do
Arifuzzaman arif o que você quer saber sobre duckweed? Ou AZOLLA microphyla? Ou ainda Wolffia arrhiza?
Arifuzzaman arif eu sou engenheiro agrônomo especialista em biologia molecular. Estudo estas plantas a 2 anos. Se eu puder ajudar.
Para cultivar em larga escala estas plantas a altura da lâmina d'água deve ser máximo 30 cm. Azolla eu cultivo a 5 cm de altura de lâmina d'água. Coloque 1 a 2 cm de terra dentro de um recipiente. Se for Azolla cuidado com excesso de esterco ou adubo. Para um tanque plástico de 2 m x 2 m coloque 1 a 2 cm de terra. 2 kg de esterco bovino velho. É 30 gramas de superfosfato. Inocule Azolla no dia seguinte. Revolver o fundo 1 vez ao dia para suspender nutrientes. 1 vez por sema 10 a 30 gramas de superfosfato. A biomassa duplica a cada 24 a 48 horas. Se for duckweed pode usar mesmo protocolo.
I can't even figure out how it multiplies. A couple of plants found their way into one of my aquariums (I have a bowl of duckweed on my windowsill)and within a couple of weeks there are dozens. So, how do they mutiply?
The leaves split
1 hectare de cultivo pode produzi 400 toneladas/hectare/ano.
Ok
What do you do? Mine wont grow
I really don't do anything it grows on its own
I've got my duck weed in Arizona it's not doing great . Water temps are 81F. and the pond is under 60% shade cloth. I'm thinking when it cools off somewhat things will change.
How do you get rid of duck weed my pond is covered
You need to get rid of every piece, if just one individual plant is left it will just start over again. I had it in my 55g aquarium and every water change I would manage it and try get out as much as I could and just kept on top of it
Put some fish in that eat it
אני אוהב אותך. 😊
I bought this hoping it would grow fast but I swear everyday I have less and less. I have shrimps, a beta, and a snail. And I have a theory that maybe the Shrimp and snail are eating it?
I agree with you 🤪
@@goforgreenliving those bastards. I knew it.
Can i feed my poultry eggs laying hens with this?
Anon Pakistani they like it better dried
goforgreenliving So it means it's completely safe right??
Anon Pakistani I have never had a problem with it
That was a lot more than a teaspoon......lol
Table spoon
@@goforgreenliving and tablespoon
Bro I can hear you talking over the music
Sorry the sound gets better later video's. Thanks for watching though
Check out a teaspoon
It was about one
It was about one
my duckweed all dies
Very sorry it grows easy here
I hate to see what he eats with.
Table spoon 😉
