Korean Natural Farming How to : FPJ

Hello. Welcome. And this is a How to: Fermented Plant Juice. This is a simple video step on how to make it. If you want the details and the scientific facts, check out my other video: All About Fermented Plant Juice For the rest of the video we will call this FPJ. The first thing you want to do in making Fermented Plant Juice or FPJ is get your materials together. Here is a list for getting all your tools
on hand. Otherwise you’ll be running around, searching for things when you have your hands dirty. The second thing you want to do is get up early before the sun rises or a little after to collect your plants. You want to get them when the dew is still on them This is best. Next step is to cut them. Today we are going to be using banana flowers. This doesn’t hinder your production of your banana. This I take off after the banana tree makes all the bananas it’s going to make. When you cut banana flowers you want to cut them about, or any plant for that matter, you want to cut them about the length of a man’s thumb, the last knuckle there. You can go a little bigger, or a little smaller, that’s fine. This is to increase the surface area when we mix it with brown sugar. So next you want to weigh and mix your material that you have chopped so nicely with brown sugar. You need a scale and a container to weigh in. I have zeroed out my scale so that container is about zero. The red marks here are the pounds. So what I’m going to do now is drop all my banana flower into my container. We have about 4 pounds. So the next thing I need to do is add to it 4 pounds of sugar. So the total weight of my container will be 8 pounds. I use brown sugar. If you don’t have any of the things in this video, see the video All About FPJ video. There are a lot of details No scale? There are work arounds. So check that out. Today we are just showing what I’ve got here. All right. That is about 8 pounds there. So now we have 4 pounds of banana flower and 4 pounds of brown sugar. This bucket is a little small for mixing. If I started getting in there and turning it
all over I’d have trouble. I’d spill a bunch. So I’m gonna use a larger bucket for mixing. Now what I want to do is I want to thoroughly turn this into itself, completely covering all the banana flower in brown sugar. It’s okay to be a little rough but
you’re not trying to smash it. When the sugar starts to appear wet overall or you feel like you’ve got a good mix. That should be plenty Next we want to place our mixed material in our fermenting jar. Banana flowers, since I’ve made it before, I know if I fill it all the way to the top it will end up about half full. You want to fill your fermenting jar
about three-quarters full. If you know it’s going to drop, you can
fill it to the top and it should go down about here. Today to show you that, I’m going to use the small jar for fermenting. Now that you filled it to the top, you can press down a little bit. Take a little more sugar and we’re going to add a cap. So what that looks like is just a little bit of sugar and it goes on top and it helps regulate some of the oxygen and that’s the way to get it to ferment just right. That looks about right. So now with this sugar I just go ahead
and evenly pat it down. Distribute it all the way to the edges of my container. Now that we have finished here, we want to go ahead and clean off the whole outside of your container. So I like to thoroughly clean both the lid and the outside of the container of any stickiness. Sometimes what I’ll do is I’ll use a little vinegar and that just helps to get rid of the last residue of sugar. The last thing you want is a bunch of ants all over your place where you make FPJ. Vinegar is great in natural farming for cleaning. It is safe and doesn’t mess with any of your fermentation and it is a good cleaning agent. Go ahead and get the bottom and move it to a clean spot. All right. Now we’re ready to put
the cap. What I do use for a cap is paper, or you can use a paper towel. Try not to use cotton cloth or or rags because they can build up with moisture and dust and create a situation for your Fermented Plant Juice that you don’t like. So I use butcher paper. This one I’ve already molded to the top of the lid here. And to cover it I use a link of rubber bands. You don’t need rubber bands and you
don’t need butcher paper. Whatever you have paper-wise, like paper towel and if you have twine or even a strip of plant material you could tie off your lid. What you do want to do is make sure that the edges are pretty secure so the ants can’t get in there. Now your Fermented Plant Juice is ready to go. In 5 to 7 days you want to check that out and the fermentation should be complete. It kind of depends on your environment. 5 days of its fairly warm. 7 days if you’re in pretty cold place. And that can vary. Check out all about FPJ. It’s already starting to liquefy there,
dropping down. We’ll see more of that. Now i’m going to show you a finished FPJ. This one I made in a two gallon jar. It was all the way full when I fermented it or when I began. See how it settled down here. There’s all of this liquid, the plant material and then our cap, the residue of our sugar cap I covered this one with the paper towel. Let’s go ahead and extract! Today to extract I’m going to use a big old funnel and just some mesh that will take out the bulk of the big material. After I extract the big material we will go ahead and strain it down finer. Don’t worry about getting all the little bits of sugar in here. We are going to use those for vinegar. The plant juice takes a minute to drip all of the drippings out of the material. Leave it sit with a cover for a period of time or if you have plenty for what you need, don’t worry about it and all of the remaining FPJ in this material can be used for making vinegar. So if you’re interested in vinegar, watch my other video How to Make Vinegar. Now that we have extracted FPJ into this big container and strained out the bulk of the big stuff we probably want to go through and get the fine stuff. This part isn’t necessary. If you don’t have anyway to strain it finer than what you’ve got. Don’t worry about it. I use a fine gauge stainless mesh. Throw it into my funnel that was made for that little piece. All that finer mesh does is gets out the remaining chunks and bits. Sometimes it’s helpful to store your FPJ in a few small containers. I store all mine in the same big container. This is now ready to go. You have finished your FPJ. Now what you want to do is put a cover on it that’s breathable. This is still going to be pretty active. And if it bubbles a day or 2 later, if
you see a bubbling and active, add a little more sugar. More about that in the All About FPJ video. Now you have your finished FPJ. Thank you for watching How to FPJ. Make sure you check out the next video : How to Vinegar where we’ll use the remainder or the leftovers of your FPJ; the waste. And we’ll turn that into a couple of gallons of vinegar with one ingredient, water. Thanks for watching.

    Good morning Chris! I was looking at Dr. Cho's FFJ recipe, do you use the fruit skin? For instance, use the whole banana, don't peel it first? With a mango, would I remove the seed? Should all FPJ and FFJ be stored in an open container? I can cover it but dont seal it with a cap?

  2. tickpicker Author

    Hello Chris, can a person use a head of cabbage you would buy from a farmers market, or does it need to be harvested from the wild to get the wild yeast.

  3. bizfactory Author

    Thanks dude, just followed it to a T for some fenugreek. Have you ever fermented fenugreek? I'm curious about the NPK but haven't been able to find an estimate.

  4. DisplayName01 Author

    Hi Chris, hope you're having a good day. Where is the all about FPJ video? I'd like to understand why more sugar is needed if the extract is still fermenting after a couple of days, the science behind it. Also, can you ferment for too long a period, lets say it was finished in 6 days but you let it sit 10, is that a problem?

  5. Christopher Cataclysm Author

    Hey Chris I'm going to make some of this today. We have lots of sage and jasmine, birds of paradise and palm in our yard, would that be good? Does it all have to be the same plant?

  6. Jeff LaPorte Author

    There's no all about video that I can find so not sure what you would use this for. Is this a marinade for chicken and pork? 🙂

  7. Dr. Vivek Author

    Great video Chris. The choice of material for FPJ-banana flower was great for orchards to induce flowering. Maybe a small discussion on suitable FPJ material depending on stage of plant dealt with will be helpful to readers, like leaves/bamboo shoots for vegetative state, unripe fruits for cross over, flowers for flowering, fruits for fruiting can get viewers thinking on what local material to use for this wonderful product!!

  8. Sahara Lopez Author

    HI Chris, may you please give us a substitute for banana flower? I live in the Southern California area. Also, can this FPJ be added during any stages of the plants life? Thank you for the videos!

  9. Noah Author

    Would the FPJ be harmful to fish if introduced to an aquaponics system in about a 1:500 ratio? And if it would be okay, how frequently do you feel that could happen? Thanks for the great video.

  10. The Things I Get Myself Into Author

    I've seen recipes that require an equal amount of either brown sugar or molasses to be added after the FPJ is strained. Is that just for long periods of storage? If so, roughly how long will an FPJ last without the added sugar or molasses at the end? A few of my sources for the added sugar recipe are: and

  11. weedbright Author

    I have always fermented different flowers and new growth leaves for different purposes but have always used molasses, whats the difference with using brown sugar. Self taught so I do things the way that works for me, but great videos and always trying to correct a few of my problems. Your LAB video was best I can find. I use old bubble bags (90 micro) instead of paper and they double as a strainer. They work great and clean easy.

  12. B Goodner Author

    Do you think this will still work with fresh Organic store bought banana peels? Does it have to be a fresh cuts off the plant? Would I be better off using Comfrey or something else I have growing? thanks

  13. Nielle Custodio Author

    Hello Chris Trump, I would like to ask is I can use any parts of the plants like leaves and fruits of vegetables on making fermented plant juice? I am still kinda confused because some info didn't tell what part of the plants to be used, while the other said that only shoots of the plants is to be used. I'm kinda stuck on making treatments for my thesis about fermented plant juice. Thank you very much in advance…

  14. Sahara Lopez Author

    HI Chris, is it okay in involve the stem with the plant that i will be using to make FPJ? Also, can LAB be used along with FPJ when treating plants throughout the plants life?

  15. Georga Thomas Author

    Great Video! Didn't learn the metric system and need to know how many cc per gallon of water for FPJ. Could you please just tell me? My old brain hurts trying to figure out L vs G. thanks.

  16. MsFredwina Author

    I have another question in trying to find suitable plants this year for this. I am trying to find comfrey to plant for later. Anyway, can I use bindweed? It creeps everywhere and the bugs don't seem to eat them. Thank you!! These videos are most helpful!

  17. Chris De Witte Author

    I just made some fpj from banana flower. I think it sat a bit too long as it smells alcoholic and is thick almost sludge like. It's this still good? Or should I start over?

  18. Georga Thomas Author

    Thanks for the reply Chris….I have been using only 4cc per gallon and my plants are growing like crazy. They are going to love a double dose! Another question please: Can I spray this on the leaves as a bug deterrent? You are so smart…great videos. Thank you for sharing!!!

  19. JustinaLindeman Author

    Hi, I just found your channel and i really like it so far! Thank you for all the very thorough explanations!

    I am wondering if potatoes would be good to use since they have a lot of potassium. Everything I've learned so far seems to use the leafy green.

  20. lolo Mk Author

    can i use refined sugar and molasses to it ? brown sugar is really expensive here ? and the plant can i use guava?? and can i add lab to it so if finish the process faster ? and what if the fruit are in the fridge i didnt pick it in the morning isit gone work ?? and can i do with liquid fpj after fermenting and if am gone dilute it what the ratio ? sorry for too much q

  21. lolo Mk Author

    too bad am limited to use only flowers not the fruit it self – a great gay made me realize this… great video … thank you for sharing

  22. aintskairt olskol Author

    hey chris,,love the vid's and im off to making them,question though,finding these ingrediants arent working out so well in the city and forget about banna flower,lol,,is it possible to use store bought fruit ,like apple and pears to make the FPJ

  23. Joel Macpherson Author

    Chris, thank you for saving my life. your teaching of master cho's methods are instrumental to the healing of mine and my best friends health. I one day hope to take your classes and become natural farming certified. but being so new, I have a question. my first three rounds of banana FFJ, they have developed a slight white molding atop the liquid, it was properly strained and a clear liquid that was stored in a cool dark location, with correct amount of brown sugar added, and is less than 2 months old, should I be including a microphotograph of the slide of said FFJ for better reference? did I just not ferment long enough. or too many variables to mention, just keep trying and keep following the directions? any help on clearing up my FFJ's so I can move onto making my OHN and everything else would be a huge help. your time and efforts are greatly appreciated. namaste.

  24. Joy Baisden Author

    Hello, I am not in a tropical area (Ohio). For the plants, can I use cabbage, artichokes, nasturtiums, wild amaranth, etc? Can you give me some more ideas? Thank you, Joy

  25. Creci Elens Author

    Hey Chris, calculating how much fpj i need for 10 hectares for the whole growing season, 7 beweekly final applications, so i need to make at least 35 liters of fpj ? is my calculation correct?

  26. AdamRDuke Author

    I live in the Permian Basin area of Texas, and the only things that grow abundantly, with little or no help, are weeds. Can I use weeds for FPJ? Most of the weeds are also toxic to animals, so I would rather not use those. Do I need to grow something to use? If so, what would you recommend?

  27. Ed Tripodi Author

    hey cris thanks so much for all your rockin videos  i watched all of them at least 5 times   one question i have  is  for FPJ  i live in ny what plants can i use

  28. V A Author

    Hi Chris, just checking. I know you don't have a how to video for FAA, but can you please confirm that the lid for FAA once finish is the same, i.e. breathable?

  29. douglas cassle Author

    Thank you Chris for teaching the language of living soil! Your videos are so helpful and straightforward, I am grateful for your time and dedication!

  30. Ahmed Alshaabiny Author

    Greetings . this is very useful indeed , where i live , middle east , the brown sugar is very expensive , may i use Molasses instead or white sugar + molasses using high temperatures? thank you

  32. Shaun Masi Author

    Thanks Chris. Just finished LAB now I'm moving on to this. It's pretty fun and fascinating stuff, i must say. Lol

    Much love all the way from Botswana.

  33. Sticky Sat Author

    Thanks a lot for offering the world these great how-to vids Chris ! 🙂

    I have one question :

    When brown sugar is added to the finished FPJ for outside of the fridge conservation, is the ratio for use still 1:1000 ? As the concentration in plant's elements should be weaker due to the added sugar, shouldn't the ration be something like 1:800 ?

    Maybe it has no importance but i'm wondering…

    Thanks in advance for your answer but no problem if you don't have the time, i'll know you're busy making the world a better place 🙂

  34. cantstopsg Author

    Do u personally recommend turbinado cane sugar like RAW or a brown sugar //light or dark? Ive been using raw cane sugar from costco but am buying 100 lbs and was thinking brown because its more accessible

  35. The panny P Author

    Yo! I'm making FFJ with some rich in K fruits and I wonder if it's bad that the brown sugar sediments in the bottom, it was all well mixed and now it seems that isn't. This didn't happen with the FPJ tho.

  36. Ben Van de Geyn Author

    I'm making FPJ using a cantaloupe and all the sugar and liquid are sinking to the bottom – will this be a problem and how can I do it differently?

  37. SAGA1MUSIQ Author

    Hey Chris, BIG UPS!!! I love your videos and appreciate you putting out this KNF series…great work! I just did my first FPJ . I mixed equal parts brown sugar to plant material after chopping up leaves and stems into smaller pieces and let it sit for 2 weeks and when I opened it, it smelled fine but there was no juice (about 10 pounds plant material) , just the solid sugar cap & the plant material, which was very wet but no juice. Can I add more plant material and sugar? What can I do? Why do you think this happened? Any insights or suggestions would be appreciated.

  38. Create Synergistic Transformations Author

    Excellent tutorial Chris, thanks for sharing. I just made a small batch of FPJ from winter cress (barbarea vulgaris). First dynamic plant here in spring. It came out like syrup and actually tastes really good. Not sure if I made enough for the plants🍀
