What I believe is the easiest way to garden, the Kratky Method still requires some understanding of general hydroponics and a few tools for measuring the waters Ph and EC. If you want to know how to grow plants in mason jars in your window, watch this video. There is also the dreaded algae to watch out for so be sure to watch to the end to get my algae beating tips for your Kratky jar garden setup.

Nice video. I was thinking for a second you were going to skip the algae issue. Covered it nicely.
Very well explained. I like to see the roots as well.
I jumped on board with you and I hope you keep at this.
Thank you so much! Glad you jumped onboard, I'll definitely be keeping at it! thank you for your sub!
Can I just say; you have an amazing smile :D Thanks for adding that bit of flair to the video - and thanks for the info! I'm looking forward to trying this method later!
Thank you so much! That just made my day! Enjoy the ease of the Kratky method. 😁
This video was great! Great method and teaching as well.
You're a really good teacher! I'm brand new to this world but am rarin' to go with a Tower Garden soon! Thank you!
Thank you so much! That really means a lot! ( I'm also seeing that this comment was 3 months ago, sorry for the late response)
Never tried that har method still i made one from an old pickle jar it seems fine but i havent put anything in it yet waiting for the seeds to crackle and grow .
I mostly grow with dwc setups easy and gives alot growth and fruit . Good explanations !!
I’m a beginner and have been watching different videos seeing different ideas and I have to say I enjoyed yours a lot so thank you for your knowledge!
Great straightforward explanation
Thank you so much!
nice video informative and straight to the point I'm planning to do this
Thank you greatly! I wish you well on your hydroponic endeavors 🌱
Hello friend. I grow houseplants in hydropony and I do it as much naturaly as possible. To avoid green water, the perfect algae eater is Daphnia magna. Iam not sure if it can survive in such a concetration of nutrients, as I dose it weekly. Another possibilities to oxygenate the water if we want to avoid electric oxygenating or using H2O2 is to add moss ball, or just part of it . This plant is super slow growing but the best oxygenator I know. It will not consume nutrients but it will produce tons of oxygen. To lower PH is possilbe to use peat moss as bottom of jar. I know this wont be Kratky anymore, but its more natural way. Enjoy guys.
I'm about to jump in! Just testing the waters, so to speak.
I'm starting my seeds on cotton balls.
As for covering jars, how about socks or a long sleeve shirt with elastic on the cuff. (This could get really decorative! Lol)
Thanks for videos. I just watched my first 2, so I have more to checking up!
*I love how shirt & to-the-point your videos are as well!
Thanks so much! Really glad you're gaining value from my content 🙏
When I was in the vegetable industry, we ALWAYS used EC meters. I bought one today actually but it's both ppm and EC. You showed it on the screen as TDS&EC, the one in the middle. Cost me half the price of a McDonald's meal.
Quart large mouth canning jars and screw on lids are the perfect size to drop the little slotted pots in.
Thsnk uou. Really helpful. My first time. Def subbed 😊
Thanks for the info. You might benefit by having Amazon associates links in description for meters and supplies that you mentioned. 👍🍻
I LOVE YOUR CHANNEL!!! New to growing veggies and I have never heard of the Kratkey method until I saw this video. I love how you drilled the hole in the lid of the jar for a perfect sized pot insert.....now I know what to do with all my jars that I have been holding on to! Thanks so much for the tips
Thank you so much for this comment, it made my day!!! I'll keep making videos if you keep watching 🙏 watch out for rust on those lids, I recommend a little tape or flex seal around the hole. 😉
who inented the term "Kratky", it is a stupid word.
@@seanleith5312lol it’s a method founded by Bernard Kratky, a researcher at the University of Hawaii who came across this way in his work there 😅 don’t think he meant to invent anything for the mainstream or even thought his name would be slapped on its label…
Hello, was that the 3 bottle bloom nutrients? If so how much of each for that gallon size jar? thank you
Make a sleeve from construction paper and resealable tape Uncover when desired.
What nutrients are you using for the plants.
I grew for 14 yra and I learned some things new from you. Hydro is the best way to grew anything atip for you and air bubbler from fish tank shop does wonders I really like the airponics setup that produces a mist in the space between the plant cup and the surface of the water. I also love the ebb and flow system because I can automate the system with a simple timer and a pump. Love and kisses Bob
Glad to know you took some valuable info from my vid 👏
This is a really cool way of growing plants. Are there any worries for pests, or are pests not so much of an issue with this method due to there being no soil media for them to lay their eggs?
thanks, just starting. i wonder can there be something more for this system to stimulate nature (like some minimal structure for roots since growing in soil vs water is so polar opposite) to make it even better, or might be just too minimal min maxing because it seems too good to be true in itself :p
Thank you
So what about how much nutrients, what kind, do you cycle the water at some point, does it chamge depending on what you're growing, etc???
I would like advice on what to do with plants that move to the cold for the winter, stop watering,....they should have their own winter biorhythm. I am in Europe where the plants are allowed to "rest" for the winter. What should I do if I convert them to hydroponics?
Hello!! Love all of your videos! Im looking to start a moving air fogponics system, because of how cool I think it is. I would really love to use clear walls of some kind to see the roots as the develop, but that makes me a little nervous... I'm designing it now and would love your thoughts! Would love to link up over messages if you ever have the chance to do a design review!
What is the nutrient solution that is used ?
is weed also compactible with the kratky method? And if so can it replace my 25x9.6l airpots? (5x5 in a 120x120cm tent with mars hydro ts3000)
I'm hoping to answer this question soon! But having never grown weed in a Kratky setup, I can't really speak to it much. That will change soon.
I'm trying it as soon as my supplies get here
I think it is but you'd be best to give it a new batch of nutrients every month or two. Apparently hydroponics with pumps is far better than kratky resulting in better quality.
Spell EVERYTHING out for those of us who wouldn't know the obvious things.
Yeah where can I find an accurate list of ppm and ph for each vegetable is their a main book for this?
Would the light reflection from the aquarium be safe enough not to get algae in your glass?
Great question! yes, it totally would, I ended up moving the jar near a window and covering the glass with a piece of construction paper :)
Hi how long do plants need for light under a hydroponics system?
I recommend starting with 12 on 12 off then switching to 16-18on once they start flowing.
Hello from Turkey. Kanalinizi yeni keşfettim. Sayenizde cracky method ile bitkilerimi yetiştirmeye başlayacağim. I am preparing to do list. Turkiye'de bu sistem çok yaygin değil. Sizden ricam, 1 LT lik cam kavanozlar için uygun karişim oranini paylaşir misiniz? Videolarinizin devamini sabirsizlikla bekliyorum.
You have to look at the fertiliser packaging. Honestly most lettuce will take 3 to 6 litres each. You're best with a larger jar. And make sure that they're painted black or covered with fabric or something to block the light to the water. Or it will grow algae.
@@OffGridInvestor thank you very much
@SuperiorZebra. A really cheap solution is to buy a packet of black construction paper, cut it the right height, encircle the jar and use a paper clip to hold in place.
I havent grown food in water but I have grown ornamental plants this way. When they get algae, I just add hydrogen peroxide. Would that work in this situation?
You got it! however now, you will want to switch to food grade H202 :) You can get it here amzn.to/3QQx111 Hope that helps .Thanks for the comment.
🎉
Do you never refill the water?
Nope, not In a kratky setup. You can certainly transfer the plant to a larger kratky setup if you want to continue growing, and so on.
Only if you get problems like the EC level (used to check nutrient concentration) or ph goes miles off. But generally not.
🥂
Has anyone tried amber jars to stop algae?
Absolutely! I actually give them a quick mention In the video I released today, top 5 kratky mistakes, But I call them uv jars.
Most people use solid dark buckets or paint the jars black.
@@OffGridInvestor I like to be able to see the water level at a glance. Just lazy...
Don't you need to change/top-up the water? I imagine PH goes up meaning less nutrient absorption, also without a pump there is less oxygen in the water..
nutrints...ha. still, great video!
Hahaha I was hoping nobody would notice. Thanks!
So it’s not for seeds??
For starting seeds, not really. But you can definitely grow seedlings once they’ve sprouted. Probably depends on the growing medium though, for seedlings I’d say rockwool is best.
I put my mason jars in old black socks. 😅
That is a fantastic idea!!
Yeah lol
Man I really don't wanna buy that expensive ass ph pen. Lol advanced nutrients ph perfect is better to me. Takes all the guess work out for a super easy grow. I jus haven't tried kratky though
So you NEVER check your Ph? I'll have to look into that, thanks! 😁 p.s the ph pen is only 10-15$$ but I understand "expensive" is a relative term. 🤙
@@humblegrowth never. Well I did just to see and it's around 7ish . No idea to really tell other than my moisture meter that has ph on it. But that is not accurate at all. Close but no cigar. That ph perfect really is that simple. It's a must if u love to grow. Not expensive for the 3 part system 20$ for maybe 5 to 6 plants. Start to finish.
@@humblegrowth the apeara pen is like 90$ I was told not to even look at that Amazon junk ph pen cause it's all over the place. I say no thank u to that
@@dmo848 Totally, that pen is quite expensive. But TBH cheap amazon pens have worked for me for years. The set I show in the video is for a EC and PH meter for like $12. 🤙
@@dmo848 Wow, that's interesting, I'm going to pick some up for sure!! thank you!
