Hydroponic Corn - Growing Corn from Seed to Harvest with the Kratky Method
ฝัง
- เผยแพร่เมื่อ 29 มิ.ย. 2024
- In this video I'll be growing corn with Kratky hydroponics! We take corn from seed to harvest with this plant, showing all stages of corn growth and doing everything with hydroponics.
We'll be going through all of the following:
Germinate corn seeds
When to feed seedlings
Corn stalk and leaf development
Silks emergence
Hand pollinating corn
When to harvest corn
Let me know your thoughts on this grow in the comments below! I'd love to hear from anyone who has attempted to grow corn with hydroponics. There isn't a ton of video content or information that I've seen of how to grow corn with hydroponics, but I believe we can come together as a community and figure this out to get bigger and better harvests!

Who knew corn would make a stunningly beautiful houseplant.
Yellow and withered leaves
= Nitrogen deficiency.
Suspension of growth, mixed grain sizes (small and large)
= Potassium starvation.
K helps with a firm, healthy stalk.
P helps with big root system. Also results in higher crop quality, faster crop maturity, and increased grain count.
Corn loves lots of sun. The ideal growing temperatures should be from 60 to 95°F.
Leaving the roots soaked all the time does not allow the roots to fully develop.
Ideal pH is between 5.8 to 6.8.
Thanks for sharing 🙏
So would a regular siphon system circulation work with corn?
This type of yellowing is a typical symptom of iron deficiency.
Iron is not able to be remobilized from older to new leaves in a deficient plant, unlike nitrogen or magnesium. Therefore, Fe deficiency is characterized by yellowing of the youngest leaves. When growing corn hydroponically I had the same problem, which I solved by adding DTPA Fe in the solution and the corn leaves turned green in 2 weeks.
So it sounds like he might be able to make it work if he;
1) Gave it more fertilizer (including supplement with iron)
2) Put it in a flood and drain system rather than DWC
3) Got a stronger grow light (and maybe put it in a tent that had reflective walls so that light would be reflected onto all parts of the plant).
95 degrees is almost boiling point by world standard.
Very cool! Try growing with 5-6 stalks or 10 to 12 in the same growing area if you can (as in all getting same water in same tub). Corn is designed to grow in groups, it may grow healthier. The yellow could be due to loneliness of the plant.
Other than that looks good, a fun try. Good on ya.
Thanks for sharing, Draig, that’s an interesting idea!
@@JimmyBHarvests of course. I love your system, so cool in the city. Good, great job! Have a happy
I love you Jimmy B! You've got the scientist spirit that the gardening community needed
Thanks for the kind words! I greatly appreciate it! 🙏🙏😁
Jimmy, you'd make a fun friend. Awesome experiment.
Thanks for the kind words! Glad your enjoying the content!
...also, another mistake I made initially in my 5 gallon home depot buckets was filling the solution too high. By keeping the solution level at only about 70% helped oxygenate the plant better
I used to add like 5ml of hydrogen peroxide per 1 or 2 gallons of water helped keep it oxygenated looking to try this at home too thanks 4 the video !!
Breaking new ground! God bless you, Sire.
At least you tried. That was fun to watch. Thanks🇨🇦🕊️
Super appreciated 🫶🏻
I'm loving all of these experiments! Growing corn indoors!! WOW, you're an innovator
🙏🙏
thanks for sharing the information.
As always, very fascinating!!
Thanks brotha! 🙏🙏
I love this video. Very open and honest with your experience. I’m new to your channel so I want to tell you that’s it’s great to watch a you tuber that is giving the details with time lapse and the final product.
Thanks so much! Happy to hear you enjoyed it and found it valuable! 🙏🙏
Hey Jimmy - had the same exact problems you had when I did the same exact set-up in my condo 3 years ago. The second go around, I bought a clip on light on Amazon for under $20 bucks that had 4 separate wands. I used the 4 wands on the lower leaves. On the 3rd go around I started spraying the leaves with folige fertilizer spray every 10-14 days. I used the same spray recommended for indoor meyer lemon trees. I think it’s called dyno grow foliage spray
...keep in mind there are different kinds of foliage sprays “M-P-K” and there is a difference between indoor sprays vs outdoor sprays
Very cool! How did the second attempt turn out after implementing those changes?
The next go around worked great. I think giving all the leaves/lower leaves more grow lights helped turn my leaves greener
So neat!! Going to try this with both aquaponics (fish) and soil, indoors!
Good luck!
Thanks for the idea never thought to try corn. Going to put some in rockwool right now.
Love it! Best of luck with your plants!
‼️Jimmy B. MacGyver‼️
Thank you 👍 for showing us.
Since we don't have a long sunny summer periods here in the North of the Netherlands, we should give it a try starting indoors and let the corn grow further outside in our garden. 🌽
Did you ever use the Kratky method outside for saving water?
Greetings from the Netherlands
👋👋
Cute corn! I'm guessing you had a nitrogen and/or magnesium deficiency , judging by the leaves. Great experiment! Very fun!
🙏🙏😁
@@JimmyBHarvests Just put some banana leaves in water in a closed lid box for 15 days and use as fertilizer 10 to 30 ml
@@sagaspace Where does one get banana leaves?
@@scott98390 from a banana tree farm
@@scott98390 You don't need banana leaves, you can just use the old banana peel. Personally I don't buy any feed, I just put all my kitchen scrap in a bucket of water and it rots and turns the water black> I then dilute the black water with the water in the hydroponic setup. The spare pulp can be left in and keep going, but the competitive inhibition of bacteria on it kind of slows down the decomposition so instead I feed it to a worm farm. I use the soil from the worm farm for in soil planting like potatoes, or sometimes dilute a little bit of it in a kratky style hydroponic setup for the nutrition, but soil makes the water viscous so it won't work in any hydroponic system that uses a pump.
Which brings up the other factor that aeration of the solution may be why the corn wasn't doing well. Even if roots above are exposed to air, plants do much better when the solution itself is aerated.
I did this but outside, last year. It was very stunted and had stripes like yours also, i think mag deficiency but my nutes never fixed it with more. Prob need differnt nutes. Great vid
What do you use to create air flow? That makes good, heard stalks. What you had was an ear of corn that would have been more adapted to hydroponics. Next time, get open pollinated dwarf (like Bantam) and save the seeds. You also need more nitrogen and potassium, and perhaps more phosphorus. I like water from worm beds.
maybe could have benefited from some fans, its a good point!
I hope you're trying this again this year! With a few changes I think it can work!
Vertigo by the window
Really cool video I didn’t know anything about corn until now lol, it would be really cool to see you do a hydroponic pumpkin on your balcony, I just bought some heirloom seeds off amazon that are supposed to produce giants and was thinking about trying to do it in some kind of hydro medium in my grandmas yard. I wouldn’t suggest using these particular seeds on your balcony though you won’t have any way to dispose of the pumpkin when your done other than drop it lmao.
😂😂 glad you enjoyed it! I just did a pumpkin grow with hydroponics, you can watch it here: th-cam.com/video/PkreRrS-YcE/w-d-xo.html this plant was super fun to grow and I think it did well in the hydroponic environment! Next summer I definitely want to grow another one outside, either on the balcony or in someone’s yard. Super excited to give it another try!
Jimmy's next experiment.. "growing General Sherman tree indoor.. hydroponically"
😂😂😂 I like where your heads at! I’m really interested in trying a few hydroponic trees
this is what the first Mars colony will be eating
😂 agreed
Again another great video . You should try to grow potatoes using kratky . I've always wondered if it'd work
That’d be a fun idea! I’ve wondered that myself!
U use wool cubes!? Cool!
Awesome video as usual!
Lack of light my friend. An HLG Scorpion Diablo would pump out some nice corn I bet! A fan blowing a slight breeze on them would also cause them to build up tougher stalks to be able to support themselves. How high did it end up getting? Did you swap nutrients to more of a bloom cycle when it started flowering and silking?
Thanks Tom! Plant was probably 4 feet tall at the end, after I had cut off the tassel completely. And yes, I added a ton of flowering additives while it was sulking and the ear was beginning to develop. Was up around 1400ppm which I thought was high. There’s a very broad range listed online as ideal. I look forward to trying this again with some summer sunshine!!
If you add an airstone to the bottom of your 5 gallon bucket you will have healthier roots and much better results in all your hydro growing
Good🌹
"If you don't know what doesn't work then how can you know what works best".
Amen!
This was actually pretty successful and I think if you planted more you'd have done better. Corn apparently likes to grow in clusters as opposed to the traditional rows. I had a lot of success with an outdoor grow due to a very tightly packed row that I planted. I intend to try this but to put four netcups on one bucket and a chickenwire support cylinder around it. You have a good proof of concept, either way. I think you may have just harvested a little too early, since I had some cobs like that from my outdoor grow.
Thanks for the tips. Best of luck with your grow! Please share you’re results
Just put a multicolor corn 2 weeks ago, will try with combining the nutrients from GHE flora series to try to make it stop growing to tall and flower earlier instead.
Best of luck with your plant! Be sure to let me know how it turns out! I went heavy with flowering additives once silks showed, but it didn’t seem to be enough
@@JimmyBHarvests Ok I will, maybe I'm gonna buy dwarf variety seeds in the future as well. Thanks for the input!
If you put it in a reflective tent thing, it would have done better. Yellow leaves mean bad nutrients, nitrogen probably.
Hello Jimmy B., Greetings from N. Kentucky! I stumbled upon this video, while attempting to find one specifically for growing Bantam Corn, Hydroponically, so I watched this from beginning to end. I'm just learning about hydroponics, and recently purchased a basic setup (Hydroponic tank with 5 inserts) from Menard's, here in Florence, KY. I've never heard of Kratky hydroponics, so I'll need to learn more about it. My biggest challenge is how exactly do your go about doing the pollination, for indoor growing? My main reason for choosing the Bantam variety, is because they are the perfect size, for confined spaces, as they grow a maximum of 6 feet in height. I'd really appreciate any information you might be able to provide, regarding indoor pollination. Incidentally, the video was so informative, that I went on to watch a few more of them! Thank you!
Pollinating corn is pretty straightforward! When the tassel opens up top, grab it off and rub it on the plant down below where the leaves emerge from the stalks. The tassels are full of pollen. I think i demonstrate this in the video.
Best of luck with your grow! I will have to check out this bantam variety!
My comment is 2 years after the video posted and the video poped up on a Google search of all things..
I'm looking into corn as a candidate for a hydroponics/aquaponics greenhouse I want to set up. The nitrogen deficiency might be covered by the fish side of the aquaponics system. Fish waste and certain bacteria make nitrates.
It's also good to know that an all around uv setup would likely work better than just overhead. I don't know if I will have transparent walls on the greenhouse or go straight UV only with solar panels. Thanks for the proof of concept video and I appreciate the propagation portion.
Best of luck with your set up!
I'm trying some veggies in dwc for the first time. All in doors. I'm trying to do three corn some kale some lettuce tomatoes peas and green beans. I don't know how it will work but I'm trying to use that liquid fish fertilizer for nutrients I'm just using quite a bit less than what it recommends when your spraying and on the soil I can always add more later
Thats awesome! Best of luck with your plants, you've got a great variety there. Should be lots to learn!
that a hardcore Nitrogen and magnesium deficiency , you could use a aquarium air pump roots like aeration, that why more professional avoid getting the roots 24/7 under water , one method spray them from time to time
Here you go... Fertilize the plants with a 16-16-8 liquid fertilizer when the corn plants have reached a height of 4 inches, but before it reaches 8 inches tall.
Fertilize the plants again when they are about 10 inches tall. This is best done by side-dressing, rather than applying fertilizer directly on the young plants. For this application use a 46-0-0 (all nitrogen) fertilizer product.
Add nitrogen one last time once the sweet corn ears begin producing silk, using 46-0-0 nitrogen fertilizer according to product application directions.
Hope this helps you out!
Thanks for sharing!!
My hydro is outdoor , I have 18 buckets , I'll try corn, and just corn my peppers morphodited because I mixed them with tomatoes , the tomatoes dominated and starved out the peppers from nutrients. Thanks I'll try this
Sorry to hear about the peppers- live and learn! Good luck with the corn!
This was really neat to watch! By the way Jimbo do you mind letting me know what P.H and TDS your tap water is? If possible please. Im trying to re create your cloning method for my first kratky tomato grow. Happy belated Thanksgiving by the way!
Glad you enjoyed it! My tap water comes in at a ph of 7.2 and TDS of 120. After adding in my nutrients it would ph in the 6-6.1 range, my TDS with this corn was 1100-1300
@@JimmyBHarvests You're the best Jimmy! Thanks so much man!
This was so funnnn. Did you just end up eating the corn?
I sure did!
You did not tell us what hydroponics solution combination you used......
This was a very interesting experiment.......You did succeed
I grew this with nutrients from Future Harvest. These a link and discount code in the video description!
I planted some corn I germinated on soil but some remained so I'm interested to check if they can really grow with kratky method...
Do you used just tap water or also nutrients? What kind of nutrients if so?
I used tap water and nutrients. RO or distilled would be even better if you’ve got it, but not necessary. I used Future Harvest nutrients for this plant, and use Advanced Nutrients often as well. I’ve got links in the video description to where you can find both those products
Calc n mag needed for photosynthesis
the yellowing is beautiful. stop picking on it! It just wants to be itself. Who are you to judge if that's weird
Also... KoRN is not food. its barely even music
...reading the other comments, although initially, most hydrophobic growers think it’s a nutrient issue ie had problems with end rot with indoor tomato & zucchini plants, it usually has more to do with filling your solution too high and not allowing your roots to breathe in oxygen. Assuming, you are using the right portion of your nutrient solution & making sure you mix the ingredients in the correct order....you will eliminate most issues involving the roots inability to draw up the nutrients needed for the vegetable to grow healthy
...and as you already stated, you need to provide enough LED/grow light to green up the leaves. Also foliage spray may help
Thanks for sharing all these tips Todd, great stuff!
Thanks for all the fun videos. They are professionally made. I am too lazy and don’t know how to edit videos. I know that it’s a lot of work making videos and putting them together. It’s enjoyable watching your videos!!!
ph levels checked regularly? if hydroponic then should be in the range of 5.9 to 6.2 (more acidic in hydro setups). the water source also influences the health in hydro; if tap water is used then make sure you've left the water to sit in an open bucket for 24 hours to remove chlorine additives from municipal water sources before adding. adding about a quarter tab of the regular Vitamin C (crushed up) will also remove the chloramine if your water source has that added too. afterwards, do a check on the ec of your water source before adding feed/fertilizer. if using distilled or RO water source then your EC should be near 0. btw, EC is a more universal standard to measure dissolved salts in a solution. Others in the hobby less commercial refer to a TDS measurement when determining the amount of fertilizer in solution but TDS levels can vary from meter to meter (based on how the manufacturer programs their algorithm into their device) so if you have a meter that measures both tds and ec, best to convey EC measurement as it's universal on all meters.
ec levels in hydro should be dependant on the amount of light your plant is exposed to. the more ppfd delivered to the plant, the more EC you can get by without burning. most nutrient/fertilizer feed charts assume you have your plants in direct sunlight (for the ppfd measure) so don't need to feed 100% to the feed chart (more like start at 30% and work up until you notice some tip burn, then scale back a bit and that's your sweet spot). It takes about one/two grow cycles to better understand how your environment is affecting your feedings. we usually grow at an EC of 1.1-1.6 during veg and 1.8 during the flowering of any vegetables and that's under a ppfd level of 1450. any supplemental light source needs to consider the natural light when considering if you need to supplement with a grow light. if growing indoors even next to a window with sunlight, adding blue light to the spectrum will cause the node spacing to be smaller, which is better for the indoor growing of corn.
Thanks for the info Ryan. Looking forward to my next corn grow attempt
It needs nitrogen. What do you have in the water?
You need aquaponics not hydroponics for corn probably. amonia > nitrite
Thanks for sharing these tips
Heavy feeders lots of N
Could have been magnesium deficiency. I think I may try this!
Best of luck! Would love to hear if you have success!
For yellowish , you must spray the plant with npk191919
Corn needs a LOT of nitrogen. Maybe plant some beans in the same bucket to help
Great tip, thanks
Great try. But you did get better results than my corn did outside in garden. Im afraid i can be no help at suggestions. My first thought was that it doesnt get enough sun, or correct temps. to be happy. Im thinking yellow sometimes means just too much water. Ebb and flow might produce a better yield instead of it sitting in water. Maybe it needs iron. If its too cool the corn has trouble absorbing nitrogen. 80 to 90 f degrees is best for corn, is what i read. Great project.take care.
Thanks for sharing! Definitely more work to be done trying to crack this code of growing corn with hydroponics.
I'm trying to grow corn inside right now. There's VERY little info online
💯! Best of luck with your corn, keep us posted!
Only sunlight is the problem here
maybe the plant is yellow because the light is on constantly? drying the plant out? it needs a fan for wind as staying still forever is boring and also tone of darkness and coldness it needs at night.
Didn't know corn grow this fast. Sick and tired of 90 days tomatoes, melons and peppers
It was a pretty quick plant! Peas are another fast one
Keep trying!
🙏👍
Those corn plants need sulfur very badly. That's what's causing the green lines on the leaf
Sulfur eh? Thanks for the tip
@@JimmyBHarvests yep. Healthy plants should be dark green with the corn stalk being the diameter of a half dollar. Usually capable of supporting their own weight at maturity without toppling over. By the looks of your the ear, you were also deficient in N&P&k (nitrogen-phosphorus-potassium) the most important nutrients ahead of sulfur. At best you could have 2-3 ears growing on it with each ear counting 16-18 kernels around and 40-60 tall. You're welcome 😊
👍🤙💪🌱🌳✌️
🙏🙏😁
Chelated iron
Some aquaponic youtuber said the stripes in the leaves is typical for nutrient deficiency. See: watch?v=vDjgUz__Ss4&t=1m43s
Thanks for sharing
Its nutrient deficiency, looks like N deficiency
No nitrogen dude
Just seed and water is not enough
It was fed a typical nutrient schedule
Corn needs a lot of nitrogen like every other day
PH issues with the corn.
What ph do you recommend?
I've gotta delete corn porn from my search history now.
😂 don’t be ashamed of it, be proud!
Didn't want to call your neighbors over too enjoy your wonderful harvest? How rude of you!
😂😂😂
The yellow seems to be the result of a nitrogen deficiency
That was my initial thought / finding as well.. I doubled down on nitrogen in my feeding schedule but saw very little change thereafter.
@@JimmyBHarvests Is it possible you have nitrogen lockout? Also, when I grew corn over this past summer, the research I did said that most of the nitrogen the plant would uptake was within the first few weeks of growth, I'll see if I can find a source for that, but it's possible once you identified it, the plant was no longer taking it up and was essentially doomed to be yellow.
www.beckshybrids.com/Blog/ArtMID/841/ArticleID/89/Agronomy-Update-EIndiana-Ohio-Sidedressing-Nitrogen-Rates-In-Corn
From what I can see, it looks like the leaves remained yellow because once it started to tassel out, the plant was using the nitrogen for that and to then produce silks, so the leaves did not get any extra care. I hope this all helps!
