Easy to Grow Hydroponic Lettuce Using the Kratky Method
HTML-код
- Опубликовано: 16 мар 2018
- This video shows how to grow lettuce in glass mason jars hydroponically, meaning in water instead of in soil. I use the Kratky method, which does not need an air pump. A simple glass jar is good enough to grow the lettuce as you will see. The seeds sprout very quickly, and in just 5 weeks I have a beautiful harvest! After another 2 weeks the leaves grow back and I am able to harvest a second time! Very delicious both times!

Tikki O. Hi I am new sub on your channel I lake to know if you check the PH on the kratky method if you do how thanks
I would like to go to the links but this phone is not very good .
Hi, thanks for the nice informative video. One question I have to ask is, after the first harvest the nutrient liquid was about half finished right? So at that point do you refill it to the original level or can we just keep the jars with that left amount of liquid and continue for the 2nd harvest? and so on?
Awaiting for your kind reply!
Cheers!
Tikki O. I thank you, much love to you

I've gone through dozens of videos on hydroponics. THIS IS LITERALLY THE BEST MOST INFORMATIVE VIDEO I'VE SEEN. THANK YOU!!!
I was thinking EXACTLY the same!!
Same boat! There are so many that leave out little details. Like lights, harvesting etc etc....
I am glad I found this channel. THX
You can say that again - aye aye
She doesn't keep a secret
And she is painfully meticulous in explaining the minute details
I love this thorough attitude
I hate those videos that take forever to say what could be said in a few minutes. Lots of sizzle but little sausage.
I love how you present this information. There wasn’t a lot of subterfuge or fluff. Everything you said served a purpose for me the Viewer, and I appreciate that immensely. Not once did I find myself saying: “Would you get to the point?” Because everything that was presented was to the point. Thank you for that. I also appreciated the information because I want to start growing using this method and after having watched your video I feel confident that I can do so successfully.
I am glad people like you exist !!!
Yeah me too .. In. Like she tell me whe she do like that n this
I watch a lot of RUclips gardening videos, and this has to be one of the most informative ones I've seen. Your presentation was extremely concise, and well structured. LOVED IT
muddywaters, thank you so much, it means a lot to me! I am trying to do better each time I make a video, its a learning process.....I appreciate the comment!
You took the words right out of my mouth with your comment.
muddywaters, she does a great job on her vids.
If you have watched other videos and compared it to this one, you can easily spot the nuggets of information. I agree that this video is very valuable to those starting off in hydrops.
Agree.
Finally a simple and to the point video. I swear most of them are just trying to brag up their huge setups. Thank you for some common sense!
There are so many videos on hydroponic growing, and I found myself overwhelmed. Everything is on such a big scale and seems to require so much start up money. I feel blessed that I found your video. The way you presented the information and reasons why things needed to be done a certain way was SO easy to follow and understand. I plan to get started using the method you've demoed immediately. Thank you so much!
Thank you for sharing as I am trying lettuce myself
I watch a lot of hydroponic videos on RUclips and yours are by far my favorite because of your production, your commentary and clear instructions, and the fact that you follow up for weeks and show how the plants grow! Well done!
Wow, thank you, I really appreciate your comment!
I love that you showed the plants step by step and really explained the how and why! Thanks!!
This has to be one of the most informative videos that I have watched on RUclips in a very long time.
Thank you, I appreciate that!
Very thorough and detailed, making the Kratky method simple to understand with no questions needed to get going. thanks!

Nice job Tikki. Definitely going to look into this as alternative to compost and a small outdoors greenhouse.
Well done.
Thanks for making an easily understood video for a beginner!
Good luck! Thanks for the nice comment!
Great job!!! I love the simplicity of your setup with the jars and paper covers. Great job I learned a lot. Thanks
I just decided to try hydroponics and found your video. All the information I was looking for, clearly presented without without distracting chatter, great video. Thanks!!
Thanks for the comment Carol, good luck growing!
You are the first one I’ve seen to explain the air gap and the need/reason to cover the glass.
You get a like and a new follower.
Good job.
This is amazing. I love that you showed the progression of them growing.
Thanks Steelroo...good eye!
Yes! That was very encouraging!
This is by far the best hydroponic video I’ve seen. Thank you so much!
A.V. I appreciate that! But I think there are many good videos out there better than mine, and I will keep trying to do better. Thanks for the comment!
...they grow back faster after your first harvest because the plant has already established its root system and so the energy is going directly to producing leaves.
Ken, thanks for explaining that!
the larger jars were closer to the light source? (higher)
The larger jars have more oxygen at the root zone which is why I suppose they grew better. If these net posts were planted over a large reservoir with an aerator pumping oxygen to the roots instead of individual glass jars they would do even better.
Beautiful
Right Shawn - Oxygen is a huge key as to how well a plant will do in the Kratky Method. Dr. B A Kratky explains this in his wonderful document. I like the 4 page version. www.ctahr.hawaii.edu/hawaii/downloads/A_Suspended_Pot_Non-circulating_Hydroponic_method.pdf
This is by far the easiest to follow hydroponic video I’ve ever seen. Thank you.
I watched your video back in August and you made everything so easy to understand, you inspired me to try this method. It worked! I’ve harvested a fair bit of lettuce as well as arugula, kale, rapini and herbs. Thanks so much for the valuable instruction.
Thank you so much! This makes it seem so much easier! I can’t wait to get started!
Great to hear that Mr. Kat. My suggestion is to try different varieties of lettuce to see which you like best. Good luck!
I love your presentation and the way you get to the point and don't bother with idle chatter. Your videos are very informative and I've subscribed as I don't want to miss any. I'm excited to start a Kratky garden due to your easy-to-understand videos.
Thanks for the quick response. Happy gardening!
you too!
I agree with the comment section. This is the second video I watched from this channel. It's always so informative. Thank you so much for this.
This was the best video for a newbie. Thank you for doing such a well made video.
Shakti, thank you!!!
This video is fantastic and very easy to understand for beginners. Thank you so much 😊👏
Dyastri Intan, thank you, I appreciate the comment!
Truly one of the most concise and informative Hydroponics videos I have seen, for a beginner to start with. Subscribed!
You've inspired me to try to grow lettuce. THANKS!
Very clear and informative. Thanks for sharing!
Wow it must have taken lots of days to make this video,
Thanks for being patient
I just started growing my herbs and I have them in the window . I did not realize the root system should not be in the Sun. Your video has helped me more than anything that I have seen on RUclips yet. Thank you so much for sharing I learned a lot!!
Thank you Toni for the feedback, and good luck with the herbs!
I am as novice as a novice can be when it comes to gardening and have been watching dozens of similar videos. You pretty much covered everything I need to know in a very clear and concise manner, and left no stone uncovered or left any gaps in the process like many other videos do. The only minor thing not mentioned is whether you had to refill the liquid after your first growth cycle.
Thanks for helping me decide to go with “grow big” as opposed to Masterblend. I wasn’t looking forward to measuring the 3 separate portions.
Thanks Chainsaw cruz. If the container is big enough you don't have to refill. But if your container is small, or if you live in a very dry environment then you will need to refill. There is no rule, it depends on your growing environment and container size. If your water evaporated or it was in a small container, then toss out the remaining liquid and give the plant a fresh drink of hydroponic nutrients midway through the growing cycle. Thanks for the comment, I appreciate it!
Great video Tikki! I just started Kratky Hydro for lettuce! I do 5 things different that will save you time and money: 1.) skip the hydronton pebbles 2.) poke 5 holes in your rock wool cube with 1-2 seeds in each 3.) no need to remove seedlings and transplant 4.) stick rock wool with seeds in netcup in solution directly under CFL bulb (hood lamp) - about 5-10 inches. 5.) leave on 24 hr light cycle
you will have lettuce in about 2 weeks! : )
Good luck! and I hope this helps you save money and time! (I use romaine lettuce, so you can leave multiple plants in one rock wool versus buttercrunch where there is only room for one)
nonetheless - you dont have to buy expensive LED or grow light bulbs....cfl only costs about $3-4 dollars. i use master blend as well!
Hope this helps your harvest and your wallet!
Zin Min, thanks for the tips! I leave the seedlings in the rockwool, I don't transplant. But I have the lights on for 16 hours a day, not 24. I wonder if that makes a big difference in growing time? In nature the plants have daylight and then night time, so it makes sense to have the lights off for a period of time. I will experiment with your way and see what happens, thanks again!
@@TikkiOOO sorry - i meant "transplant" the extras out and leave the single in. i thought they would prefer a break too! but, i saw an experiment on jeb gardner and he did it with basil...so i figured i would try with lettuce. i think he did lettuce too! lol this way really is as mhpgardner says, "set it and forget it" - i only do leg work in the hole punch, cutting neck for powerade bottle, aluminum foil, and mixing solution. after i put the seeds in - i sit it under the hood clamp with cfl 6 inches or so (the closer the better because the seeds should be short and fat - not so leggy in the beginning) - you can slowly adjust afterwards an inch or 2. i only touch them to admire the white roots! lol : )best to you tikki! you look like you are having as much fun as i am!
@@TheZinminjr Thank you for explaining!...and yes, it is fun with a healthy purpose....the best kind of fun!
HI CAN YOU ALSO MAKE A VIDEO FOR US?! THANK YOU
Hi Tikki! Did you want me to make a video? I would love to! :)
Thanks so much for sharing ! ! This answered a lot of my questions. I believe some of these tips will help me get a lot more success from my own system. Keep sharing.
Glad it was helpful!
This is a very informative video and I appreciate how rapidly you move along. Thanks for making this!
Wow, best video I’ve seen so far +1!!
This is one of the best intro to hydroponic videos I've found, thanks for being so clear, concise and informative!
Scott, THANK YOU for such a nice comment....putting videos together is a learning process.....appreciate your feedback!
Lettuce hydropon
Have you ever tried to trim the roots back a bit to slow the regrowth of the plant to see if this reduces the bitterness of the 3rd and subsequent growths?
Thanks for this video! I love that you went from start to finish in a clear, concise way... awesome!
Thank you Paul!
Very helpful! This video is great, thank you for sharing your knowledge! I want to try this come winter!
Marissa, thank you for the comment! Try growing microgreens as well, its great to have fresh greens growing right in your kitchen! If you are new to microgreens, start with sunflowers and/or broccoli. They are very easy to grow!
You rock! Thanks for another awesome video!
Jason, thank you for the nice comment!
The larger mason jar lettuce plants could also have been growing faster because they were closer to the light source as those jars were taller
That was very informative and probably the first hydroponics video I watched start till end without skipping. Thank you!
Wow, thanks for the nice comment Sriram, I appreciate it!
I have watched several hydroponic videos, but. This video is much easier to understand than all those i have gone through.
Thanks again for another very informative video.
One question, do you refill the jars for second and third harvest with plain water or still add the fertilizer?
I'm going to grow some "lettuce" too.
Z Phish....go for it!
You mean broccoli 😁
🍠
This is exactly what I was looking for. Just purchased everything! THANK YOU!!
Don't forget, use Rain Water or Spring Water. DO NOT use Tap / City Water !!!
Thank you !!! I especially appreciated you comparisons between soil/smaller /larger jars !!! Hope to see some more ...
also - i just use 32 oz Powerade bottles - wrap them in aluminum foil to keep algae growth from blooming. so far - great, fast results. i use brita filtered water as well
Thanks Zin Min! If you make a video can you post on RUclips and leave a link here so we can see your results?
Zin Min Jr how often do you add water in or in between harvest?
@@meakascott4701 Hi! That's the beauty - you don't have to change it out - the life cycle almost exactly matches the 32 oz!
@@TikkiOOO ruclips.net/video/IEY5wsdDnyI/видео.html
Hi, thank you for taking time to post this for us all. Did you add any grow big solution for the 2nd and 3rd growth time frames? or was there enough to last through to when those finished?
I also want to know this
Me too.
If you add the 2 teaspoons of Grow Big to 1 gallon of water (measurements stated in the video) you can continue to add this water to the mason jar reservoir whenever it becomes low in water.
Thank you Tikki - your video is very thorough and you provided a lot of excellent points. After watching your video you've given me the confidence to give this a try.
Thank you Milo, good luck with your efforts!
Wow, I just found your channel today and I’m totally impressed. Your videos are clear and concise and really well done. Thank you for your work.
Bev Currie, wow for the nice comment, I appreciate it!
love love love this video! thank you! just wondering what happens when the water gets low? do you just refill it?
Usually that happens just when I'm ready to harvest. If it needs water then give it some, but leave a gap for the air roots, about an inch below the net cup. My mason jars are enough for the grow cycle, so I don't normally have to refill with water. Thanks for the comment!
@@TikkiOOO Do u have a video on how u mix your water solutions? Tks.
When doing the 2nd/3rd harvests do you add more of the growth water medium if the water is low?
I Do !!
Great harvest and thanks for this review 😀
I love your detailed step-by-step videos. I have a lot to learn. I haven't begun my hydroponic gardening yet. I just ordered an AeroGarden Bounty and haven't received it yet. I am looking forward to learning all I can from all the wonderful information on your videos, including mistakes to avoid. Thank you so much.
This was so helpful and easy to understand. Thanks a lot, however I wanted to ask if you did not follow temperature instructions
Yes that's what I want to know too.....and also about the atmospheric moisture content and most importantly the aseptic conditions....can I get the answer??
Great video, thanks for sharing. Re: question at 10:20, could be the extra space for roots like you suggest, or also the fact that the 32oz jars are taller and thus the plants are a little closer to the lights
Tom H.....Good Question, is the slower growth due to the smaller resevoir, or the distance from the lights, I see an experiment here....two groups of plants, one set of smaller jars vs. larger jars, but placed at the same distance from the light. If the plants in the smaller jars still grow slower even when they are the same distance from the light, maybe we would have an answer....If anyone wants to do this experiment and let us know the results, please do.
I thought about this part of the video as well; I suspect that the amount of “air space” for the plants is significantly greater in the wide mouth jars. That slightly larger diameter could be a big deal for the plants, and perhaps they feel they have more space to grow?
Especially as the water level depletes, the overall volume of space that frees up for the roots grows more for a wider jar.
But, who knows; I’m just a math nerd, not a hydroponics expert
I did have a tutoring client whose parent constructed a large solid wood grow box for lettuce, lined it with food safe lining, and hoisted about 20 lettuce plants similar to this method.
He left it outside in the back yard during spring and had amazing lettuce in a month! Your result reminds me very much of the quality his plants produced. A very solid green color, tho I’m not sure exactly what type of lettuce he grew
Excellently done. A steady and worthwhile flow of information for a new grower like myself. Thank you.
So worth watching again! Got even more out of it. Thank you!
Thank you Just Floating!!!
Two quick questions:
1) Do you keep the light on for 24 hours or less ?
2) Do you refill the hydroponic water only after it gets over or do you replace it after some specific intervals irrespective of it's quantity left?
P.s : your video is very informative otherwise, great job!
She's using a 16-hour light cycle, according to her comment I saw. I'm not sure about the re-fill.
That’s a lot of electricity to use for growing lettuce. It’s almost a dollar per day so it’s $30. I think you can buy more lettuce from stores than growing yourself...
@@dvdgalutube But at least you know what your lettuce has grown in.
It would depend on her area but still those 2 light bulbs wouldn't cost a dollar a day to run. At the most maybe, 10 to 15 dollars for the full growth cycles. At the end of the day it's also her passion and hobby, which we all spend money on what we enjoy.
I dont have single money
I use cloth instead of rock wool
How do you do that? What kind of cloth?
@@davidaforgione5709 dont know, its just an idea, i asked a u tuber he said its bad
I am looking into either pool noodles and craft sponges. But the hunt goes on. Thanks for replying though.
@@davidaforgione5709 please respond to us with your results from sponge! I am looking at this solution too as I want to use things I already have in the house without purchasing new things. There are fiber sponges and rubber sponges in the makeup world. Eager to understand the results.
@@p_roduct9211 I tried with standard kitchen sponge - I had excess tomato seedlings from my aerogarden. The roots never grew (after 12 days) Today I have transferred the seedlings to rock wool to see if the seedlings recover..
thank you 🙏🏼 it took me some time to get to your video on hydroponic buttercrunch lettuce. looking forward to the results!
The best how to video ive come across about hydro. I'll be using this method. Thank you very much for sharing your info and ideas
Greetings from India. I was looking for ideas and inspiration on Hydroponics and chanced upon your video. I think I need not see any more videos for inspiration. Never seen a video as informative and simple as yours. I am inspired.
Thanks for making this video. Been preparing for teaching my children about the different way of planting (hydroponics, aeroponics and geoponics). Your video is really informative!
Thanks Hannalyn....kids love planting and watching things grow. Good luck!
I have been watching a lot of videos and learning about hydroponics. This video has been the most informative and educational then all the others. Thank you for sharing your experience ,its very much appreciate, blessing upon you.
Thank you Guy, I appreciate it!
Such clear video.Thank you for sharing
EXCELLENT video & instruction!!
I'm sold. This looks like a better method than any that I have tried. Nice job presenting a lot of good info in a short amount of time! I will be checking out many more of your video's
Love your videos. Keep em coming. I never can wait until you release another one.
I am so jealous!😮😍😍 beautiful harvest!! They look so delicious! GREAT share!!😊😊

Wow it’s amazing your video it’s so informative. I been watching a lot of videos and this one wins it! Thank you for explaining every single step.
This is so cool it makes me want to try Hydroponics!
I am just getting started and my kids were wanting to plant a lot of fruited plants and you video answers a lot of my questions thank you.
Here is what you can teach your kids. Fruited plants are best with outdoors since they need the bees. It's best to grow things that is edible by leaves, since you are indoor.
Best vid iv seen actually, very well explained & straight forward! Tnx 🙏
You did a very nice job explaining all of this. Thank you!
Good job! I can't wait to try it!
Very explanatory with results. Congrats and thanks for sharing with the world.
