Mason Jar Kratky Method: A Simple, Inexpensive Hydroponics DIY
HTML-код
- Опубликовано: 12 фев 2020
- Growing food year-round in Colorado is a challenge so I'm moving some of my growing indoors during winter. A series of podcasts on the Living Free in Tennessee podcast sparked my interest in the Kratky Method of hydroponics...which requires no complicated setup and offered fairly quick results. Not wanting to research things "to death" I decided to get to the "doing" part. Here's step one in starting your own indoor hydroponics system.
Check out my links for the products I'm actually using!!
UPDATE: I prefer using Rapid Rooter Plugs as the growing medium instead of Rock Wool. The rapid rooter are easier to reuse.

Idea: roll a black sock over your mason jar. Makes it easy to check water.
That's a fantastic idea! Thanks!
Great idea! My husband has a shelf full of different black socks, with no mates or stretchy. Thanks!
Im starting my project this week and im using week one and two as a guide. Very helpful and informative for beginners!
Thanks for watching...let me know how it goes!
I use long black men's socks, I can just pull down the sock a little and see the water level. then wash them and re-use them again for another growing season.
That's so smart!!! Thanks for the idea. ❤
Thank you for sharing. You got to do what you got to do.
Yes we do
By far best tutorial! Ty💕
Great video. Thank you for putting this together. Planning on doing this out here in Minneapolis this winter. Assuming the rock wool is reusable as well? Look fwd to hearing from you.
Hi Lance, Thanks for watching! It is possible to reuse the Rock Wool but I've had better luck with the Rapid Rooter plugs. They seem to hold up to multiple reuses better than the rock wool. Here are the ones I use: amzn.to/33QPovt
Once the plants establish some roots you can actually just use the clay balls instead of both them and the wool. Many people use them in their aquaponics set up. But like I said, don’t do it until they have decently established root systems.
I'm just starting out with the Kratky Method, but I thought the whole basis was to get the correct size of container for whatever you are growing, fill it up with water once, and then never check it again. As the water depletes, it provide air and room for the roots to grow. By refilling your mason jars with additional water, aren't you defeating the entire premise of not needing filters or pumps?
Hi, thanks for the comment. Yes, you're absolutely correct about the concept being a more "set it and forget". This mason jar Kratky video was really just a way to share that you can use still grow lettuce hydroponically using mason jars if that's all you have. Kind of a low cost start up way if you already have jars on hand. I made another video last year explaining why I switched over to plastic shoe boxes...one of the main reasons being that they generally hold enough water at the beginning to not run out before harvesting the lettuce. You can find that video here....ruclips.net/video/Qw40p4iDEWM/видео.html
Are u going to do an update video to show the growing stages
I posted a video every week for 7 weeks. I'll add the links to the description. :)
Do you have to leave the set up in direct sunlight or under a canopy. How do you deal with rain water going into the container to increase water level
Hi! Thanks for the question. This set up is my house for growing greens year round (mostly in the winter when it's well below freezing in my area of Colorado). So, all indoors.
Ok I did everything I was supposed to & nothing happened. They were on a window seal with indirect sunlight. But it was winter. Maybe I need a light?
Hi Denise, Maybe you can provide some details so I can try to troubleshoot? What type of seeds did you use and how old were they? Was the rapid rooter or rock wool stay in contact with the water and stay wet? Is your window sill warm enough?
Hi Im a SR living in a small 1BR apt on SS...would love to try the mason jar Kratky method...its just me...so don't need tons of lettuce..lol...I really like this method due to no need for soil...but what happens if the power goes down...how do I get enough light to the plants...window N facing wall..and West facing patio protected by an amazing Oak tree..so no direct light...filtered at best...am ready to get crackin' but not sure how to deal with possibility of power outage...
Hi! It really depends on how long the power stays off. A few days shouldn't hurt too much. I've been looking into some solar powered LED lights so I'll update when I find some that I like. In the meantime, I've just posted another video for growing soil sprouts in the winter. They have low light requirements and would do fine in any room that has at least enough light that you can see your way around.
I love your pigs 😍😍😍😍😍 they are my favorite farm animals
Awww, thanks so much! I love them too. Such great personalities.
Were you able to move to using only worm castings to make your hydroponic solution?
Sorry for the delay. I still haven't tried it. After talking with several other people using kratky I think there'd be too many variables I can't control including excessive algae and bacteria growth.
I bought the 2 inch net pots and they do not fit the mason jars. :(
Which net pots did you get? The ones I linked to fit in regular mouth (not wide mouth) mason jars.
@@TalesFromtheMutiny I followed the wrong link. Since then I have returned the wrong ones and received the right ones. All fixed! Thanks.
The problem is that every manufacturer of netpot has a different lip on them. Mine also didn't fit, but I just used a 2" hole-saw on some old snap lids and they fit just fine.
I did the same and found wide lipped 2" pots on ebay and they work great.
Are those wide-mouth or narrow-mouth mason jars that fit the 2-inch net pots?
Narrow (regular) mouth.
It’s super ... what size mason jars please???
Hi, the jars in this video are REGULAR mouth (not wide mouth) quart and pint-size. I would recommend quarts though. The point size will work but you may find that you need to keep adding water more often on the smaller jars.
Are the pebbles necessary? What purpose do they serve?
The pebbles keep the growing medium covered (the Rapid Rooter plugs) so that mold and algae don't grow on them. They aren't 100% necessary but just know that if they're exposed to light then there will be algae which can compete with the plants you want to grow.
@@TalesFromtheMutiny Thanks very much. Do they also help to block light from getting to the reservoir?
@@dlm1166 In this video I'm using regular (small) mouth mason jars as the reservoirs. I wrapped each jar in brown paper to keep the light from reaching the water and causing algae growth. The net cup and rapid rooter plug then go into the top opening of the jar and that pretty much keeps light from entering the top. However, the top of the rapid rooter plug (or rock wool or whatever you are using to hold the seed/plant) is now exposed to the light. By placing a few pebbles on top of the plug you block out the light on the surface of the growing medium. If you don't use something to cover the top part of the growing medium you can count on mold or algae growing there.
Would this work with small pepper plants?
You can definitely start seeds and transplant later. You'd likely need a larger reservoir to grow a full-size pepper plant.
Nice video! how big are the mason jars?
I used both pint and quart size jars. Quart is better. Regular mouth not wide mouth.
Can I use aerogarden pods
I'm not familiar with the aerogarden pods so I don't know what size they are. I imagine they work but I've never seen them or tried them out myself. I know people who geminate their seeds on a paper towel and then transplant them in a piece of foam or even a piece of pool noodle with great success. It's a very forgiving system so you might give it a try with the pods if you already have them anyway.
very cool!
Thanks!

You're awesome! Thank you!
