I use my husband’s black socks for covering my jars, then I can check them without lifting the plants out. He has a drawer full…lol.
beautiful setup......If someone was doing this on the cheap you can use brown paper sandwich bags and write on the outside what they are. Or pretty wrapping paper they might have on hand, secured with a rubberband at the top. Your videos are very well presented.
I love these idea's thank you Linda! Very fast, easy and creative!
@@SoothingLeaf ,,,,,gift bags.
That’s a great idea! Doing this on a 3 gallon fish tank and I can just use wrapping paper so I could reuse it as a fish tank another time!
You jumped straight to the plant...how would you do your plant with the rockwool covered? A seed in the rockwool or did you start them separately and put it in the rockwool later? Because you jumped ahead, you also didn't show that the water needs to cover a slight bit of the net jar so that it can wick up at the beginning.
Another source I saw filled the net pot with clay pebbles then added seeds on top of that. But they don't have roots yet, so how so they get the nutrients? I was watching this video to see if something more is needed but it skips to once the plants are grown.
That’s so much help, thank you so much. This is clear simple and affordable.
What a super cute way to grow a small indoor hydro garden! Thanks for the ideas.
Love the chalk board paint idea! Thanks so much for sharing!
Dude, this was an awesome overview. Everything I need to get started: materials, their sizes, the media for planting, and instructions for the nutrient medium. I'm going to try this next weekend.
Thank you Justin for the kind words. Message me if you have any questions glad to help 😊out
You might want to put a rush on it. I just bought these jars at Walmart, $11.98 for a 6 pack. They may still have them as single purchase but, they’re $3.98 each when sold that way. It was the last of them and I think the same 6 pack is $41 on Amazon. But, check online at other stores and set yourself up for Walmart’s in-stock alert.
I’m just getting started, too and this is the video that has spurred me on as, I’m an apartment dweller and I really ❤️ the black matte chalk paint on them! Good luck!
Super, simple barebones explanation for the raw beginner in hydroculture. I'm planning to start indoors with some lettuce and herbs in mason jars and move on to outdoors this summer with tomatoes & peppers. TYVM!
Loved your simplified easy way of putting it across to us, especially the nutrient side which always flumaxed me....great vidio thanks.
I bought 4L glass jar for my Ghost chilli hot pepper plants, and painted them in chalked spray paint. I like the idea because the paint dried out in an hour on sunlight.
Those are going to be some hot peppers be caution and have fun!
Thanks from🇮🇳 india
Amazing video! Trying to do more off grid growth and you make ot look so easy. Tku for sharing all your knowledge.
Amazing! Thank you for your short yet informative. I'm excited to test this out!
FYI, I used this method converting a 2 gallon fish tank and a 1-2inch thick piece of Styrofoam that I cut 3 holes in for the cups. Works amazing! Thank you again!
I love to try hydroponic planting
Try just one jar. Won't take up much space and will be a fun project to do. Thank you for watching
I’d recommend a 5gal bucket with a lid (so you can cut the hole for a 3in net pot) and you can grow tomatoes!
@@zenphysician Hey, I just put mine in 5 gal buckets. How high water level with the nutrients to start? I put them in just below the bottom of the net pot. Is that too high since in the mason jars they were a little lower (I kept the jars 2/3 full)? Dont want to drown them after all this work getting them to this point!!!!!
Love the video! Keep up the good work.
Great man thank you for the info and the chill vibe
Thank you for watching glad you enjoyed it. If you like what you see don't forget to subscribe!
great idea only modification i would do is add a hole at the top of the net pots so i can run a air line to the bottom of the jar maybe a small airstone if i can find a lot real cheap but AWESOME thing u got going there
richie pimpin It wouldn't be Kratky then by adding an air line.
Thanks
Thank you for watching! I have newer updated videos if your interested check out my video feed
Great and simple
You’re video is very informative and easy to follow. You’re a wonderful speaker. The volume of the recording needs to be louder. I had a hard time hearing with my device’s volume on the highest setting. Thank you so much for sharing your knowledge!
Loved the idea, they will look so pretty on the window sill in a row!
Do you find the water gets too warm under lights or in the sun with the black paint?
Thank you for your videos. I have just 2 questions that I can’t seem to find an answer to anywhere. When growing herbs in mason jar, how often do we have to change water? Or can we just keep re-watering from the top and just add the nutrients? Thank you in advance.
watering back to the top will drown the plants
He explained it in the video, you should not water the plants at all, and wait until it is completely empty to either transport or refill until almost the top but not touch the top.
Is it necessary to paint the jars with the black chalk paint or is that just decorative? How would you know when the water is empty if you cannot see it? I guess you can pick it up and tell by I would think it would be easier to keep it clear so you can visual see. Is the dark paint conducive to growing the plant?
It does not have to be black or chalk paint only. Anything is good to use. The purpose is to prevent light from penetrating into the jar and developing algae. It will not harm plant to much but will steal away all the nutrients for itself. Which harms the plant directly. Best to use anything that will stop lights from entering. Foil works very well and is cheap option. Also double benefit it bounces lights back at plants.
@@SoothingLeaf Thank you! I was not sure if it was for the purpose of keeping light out but now I know! Thanks for such a quick response!
I understand that the black paint is to block the light to prevent algae but I saw someone using aluminum foil warp outside the jar to reflective the light. Which one is better way to do and get the good results? Thanx
They both work well I have used both options in the past but prefer the sleek look of the black jars over the foil (is more of a homemade look) although the foil does reflect the light back up a plus. Painting the jars is time consuming and you have to do several coats of paint with drying in between. Foil is nice a quick to wrap around so another plus. Depends if you want to go with aesthetics or functionality. The black painted jars warm up under the lights and keeps the roots a bit warmer not hot just warm to the touch. It does chip away after a while or if you get jars wet at all find this kind of annoying which is why I may go with a spray paint option next.
Do you have a link with how they wrap the foil around the jar, I'm very sensitive to paint?
Christi Ho'ōla Think about it for a minute, it's not exactly rocket science. Just wrap it and add some tape for extra security.
The chalk paint is a great idea. Do you find it also reduces algae?
GivingItAGo absolutely reduces and prevents any algae growth. However when the paint gets wet will chip off and peel away so just have to be careful when washing out jars. But overall very happy with the design and results
does the chalk paint keep you from seeing your water level and knowing when to add more water? how big do you let the plants get inside the quart jar?
GivingItAGo u can get them at Pat Catans
@@zepguwlthistle7924 good question. Maybe put a piece of tape down the length of the jar before painting? (cut tape lengthwise so only half as wide; enough to see the water level)
I understood the whole thing but where do you put the seed? I only saw the basil plant appear, where did you put the seed? I would love to make some of these
deezie
deezie I planted these seeds in rockwool cubes you can find the link down the description. But if you watch my most recent video I talk about the negatives of using rockwool cubes. I have switched from using rockwool to now only use coco coir. Highly recommended media, very light fluffy and airy excellent for roots. Also no pests!
@@SoothingLeaf pests from using rockwool??
If washing the jars in the dishwasher, how does the chalk paint do?
How do you know when the water is gone?
Very good
Great video. I had used 2x Rust Oleum Black Chalk spray paint and try as I may...some raised area etc allowed light. Can you suggested paint cover .the failed base?
where do i get the baby plant lol?
Grow it
Thanks for the video. Does the black ink cause the temperature inside the jar to rise?
very cool video, subbed
Did u geminate seeds directly onto rock wool or u began by placing micro greens ?
Generally you sprout in the rock wool.
You realy sound like the brother of Castor Troy in the movie Face-off with Nic Cage
Thanks for sharing. Would regular plant food work If I do not have the nutrient mix you have?
Can we call these hydroponics plants as organic?
Also how often, if at all, u need to tackle pests etc on plants.. n how u do that ?
Mn s if you use organic seeds and organic plant nutrients, then your plants will be organic. You can use a neem oil spray as bug repellent thats natural, too.
it is 1 gram or 2 grams of the Epson salt. the container I see is 2 grams but you say it is one gram.?
1 gram (Ratio 2:2:1 )
Hi sir.
I am making in small stage,
I use
Npk 4-18-38 2 gram
Calcium nitrate. 2 gram
Magnesium (epsom salt). 1 gram
In 1 gallan RO water
Current ppm 1100
Ph. 6.4
It's good for tomato plant ?
Please suggest and guide me
what black spray paint did you use? did scrub the glass jars first?
What PPM does does 2grams MB, 2grams Calcium Nitrate, and 1gram Epson salt give you per gallon mixed?
Approximately 600-700ppm
What is ppm?
Wait i'm confused. If you let the water get low before refilling, doesn't the rest of the root become oxygenated? What you're saying at 4:00.
If the system doesn't lose water by evaporation then the water decreases only if absorbed. When the water falls below the tip of the roots, then the plant will "push" to reach the water again. If you fear the system is not airtight, then you need to constantly check the water level and make sure the roots are slightly below the water level.
You should let people know that the way you handle the rockwool is not the way it should be done. That stuff is very hazardous to bare skin and the dust off them is on par with fiberglass insulation in the air...
Hi Tom, you are absolutely right to be concerned about using rock wool. This is one of my earlier videos and I have made a few newer videos discussing the health concerns as well as mold issues. Why I made a switch to coco coir and its benefits and comparisons to rockwool. Now I grow all my plants using strictly coco coir and hydroponic clay pebbles if you look at some of my newer videos. I actually have a new how to video complete step by step guide coming out within the hour hopefully helps someone out there. Thank you for mentioning this important health risk and thanks for watching!
Not really, it is not. The one used for hydroponics is a little bit different from one you are talking about. It is not industrial grade like one they use for thermal insulation. The one on the video is specially made for hydroponics (hence more expensive) does not produce dust and is made from special volcanic rock not river sand like the fiberglass rockwool for industrial purpose.
Soothing Garden what about oxigen?
U can also use foam or sliced pool needle instead?
@@SoothingLeaf I just watched a video from MIgrower and someone asked if rockwool used here is the same as used in the construction industry. He said NO. So now we have two answers to the question of safety......anything new since this answer 3 yrs ago? thank you
Awesome! What kind of a grow light do you use?
Hydroponic newb here: would you have to repour every week the mineral galon?
Can I grow from a seed or do I have to use the little basil plant?
New sub here thanks for sharing amazing I must say looks amazing
Thank you, welcome and thanks for subscribing! New videos are a lot better then my older ones. Still trying to grow little by little. Just like my plants!
It's 1 gram of Epsom Salt!
very good vdo. thanks
Do you prime the jars first before painting them? It being over a year since you painted them with the chalk paint, do you find it stays on well for you? I love your solution. I was trying to figure out a solution for myself and they all were not attractive. The fact you can write on them is excellent.
No I simply give the jars a wipe down with a hand towel just to get off any dirt or smudges and then, flip jars upside down and give it 2-3 coats with drying time in between. Although I have noticed painting jars black makes it warm up quite a bit. This causes the reservoir to evaporate much faster. I have stopped painting the jars and simply cover with colors construction paper now. Saves time and I can color coordinate plants if needed. Thanks for watching
@@SoothingLeaf Im using brown sandwich bags with a rubberband. Will this keep out enough sunlight?
Gooood video and info . thanks alot
Thank you mal dova! Best of luck on your grow!
Could you please teach me because the herb you showed was outside of the rim of the jar but the fully set up herbs seemed to be inside the jars entirely? Could you please show me or tell me how you made the jars the way those are set up now bc I'm new and I get lost easily? Is it basically the same only the water levels start much lower? Also, how long do the herbs last in the jars? Is it indefinite? Do the root systems ever get too big for the jars? Thank you in advance and thank you for your video.
I can help :)
Question 1: herb 'baskets' can be below or above the rims. I recommend doing it below, like the "fully set up" are.
Question 2: start the water at the top, refill when it gets near the bottom
Question 3: some plants will last longer than others, but all plants eventually wither and die
Question 4: roots systems ar'nt all the same, but most grow as much as they can, then stop, and only rarely outgrow a hydroponic growing space.
I d just place a paper or clothe cozy over the jar...that way I could at least see the water level and root growth by just sliding the cozy off....
Thanks for the video. I have started some tomato seedlings in 3" net cups with clay pebbles. They are around 10 days old and 1 or 2 true leaves appear on them. I am doing it krtaky in small plastic jar. The roots are not coming out of the net cup. The nutrient solution is just touching the bottom of the net cup. What could be the issue?
did you get that figured out? Please share...
sorry for late reply. Yes, I figured out it. I started new seedlings and put the net cup in tap water jar for 15 days. After a week or so many roots came out of the cup along with a few true leaves after that I put it in hydroponic solution. Its doing well now.
@@mayurshah8319 I dont get it/ Are you saying they did not develop roots because you started them in nutrients? I thought that was what you did after germination.
@@lindakean7392 you need to put the seedlings in water for few days. After that root will grow then you need to put it in nutrients solution.
Could you just put a airstone in the water and leave it to dissolve?
yes
Dissolve what?
So plants can develop oxygen roots or water roots?
Yes. A plant can develop either.
All you need is a pool noodle with a slit in it to put your plant in and set the noodle down in the top. No balls. No net cups. And, use Gesso on your jars before you paint them.
Hey man I did the same thing and my plant looks nice and healthy but it’s just droopy and soft I have my water hitting the top of the roots idk if I have to fill it up more but I need help !
sounds like insuffisant light is the problem.
Top of roots have to have some air I think
Can potting mix also be used for this???
And what about rocks and gravel???
You need something inert. Rock and gravel are fine. Potting mix... And you're just using soil gardening for nutrients and not hydroponics.
Can you transplant the plants into soil at any point?
I'm new to this but from what I heard on a podcast they aren't great transplanted once the roots get used to half the root taking in air and the rest of the roots taking in the water/fertilizer. Perhaps it'd depend on what you're transplanting though.
The plant is putting too much of its energy in growing roots than leaves. Perhaps a smaller jar would balance this.
The plant will still try to grow it's roots as much as it can, making it grow in a smaller jar won't prevent that, most plants have way bigger root systems than what people realize. Giving your plant a strong root system when it is still young is what gives them a good foundation for stronger healthier growth as the plant matures. If you really wanted to, though, you could carefully pull the plant out and prune the roots to encourage the roots to spread and create more surface area, pulling in more nutrients and water and giving an even healthier plant. This is the concept exploited by fabric grow pots, the root reaches the fabric at the edge and the soil won't maintain it's water content as it's split between evaporating into the air through the fabric and being absorbed by the roots. This stunts the end of the root encouraging the root system to branch out and create more smaller roots. This is called air pruning, if you're that worried about root growth you can prune the roots yourself as mentioned above, to give the plants more nutrients and water for "above ground" growth.
More roots more nutrients the plant can soak up.
Are fertilizers necessary? Or its fine without fertilizer? What are the pros and cons of having and without having fertilizer? :O
Patrick Absulio
Adding fertilizer
PRO: the plants will grow.
CON: costs money.
Not adding fertilizer
PRO: don't have to buy fertilizer.
CON: plants don't grow.
You should really read up on how plants work. They need more than just water...
WITHOUT FERTILIZER: All plants can sprout, and grow an inch tall without fertilizer. Certain plants will even thrive for a limited time if they have ample sunlight. After a while the lack of nutrition the plants can get (it sucked the sparse minerals from the water and consumed its endosperm food) begin to slow down, and stall its growth. Then it stops growing completely. They may survive for a while before starting to die. Some plants need very little nutrition and will slowly shrink over time depending on if water and sun are regularly available.
WITH FERTILIZER: Plants that get access to the nutrients they need are able to grow as big as they can and have energy enough to make fruit or vegetables as well as regrow their leaves so we can pluck those to eat. When a plant has all the nutrition it needs it is healthy and can fight off and survive diseases and regrow damaged parts of itself. Most plants require certain amounts and types of vitamins and minerals to thrive. Fertilizer is the name given to all nutrients that we can give to plants and is a very simple way to get plants what they need to be useful to us.
Can you do tomatoes
Currently have dwarf tomatoes growing. Just posted video about update other day. More to come for sure. Thanks for watching
Can I use cocopeat as a growing medium?
Yes
Why do you use the bigger jars rather than the regular ones?
The wide mouth jars fit the 3" net pots better
Did u need to change the water ?
And how ?
You don't need to do a full water exchange. You just need to top it off. Pick up the net cup and pour more water in.
thanks, I was just about to oder the rockwool. I won't I will order the other
deezie
No problem, if have some time check out my video on transplanting coco coir into hydroponic system works great! ruclips.net/video/r5ChpLcR_7E/видео.html
Here is the Coco Coir that I use - Grow Media: amzn.to/2ou8uUI
Soothing Garden
How often we need to change water?
In kratky, you don't add any, the roots chase the water and it also air prunes the roots
Why cover the jars with paint?
It keeps algae from growing. Algae loves light.
@@smile4menow222 thanks.
Can I use normal npk fertilizer
No
@@TacticalGhost007 then how do I get the kind of fertilizer you are using cos here in my country hydroponics is not popular here so materials and fertilizer used for hydroponics are not available. Can you help me get some
@@kwameklu4613 Amazon delivers to most countries in the world. Have you investigated that option? Sometimes the delivery charges are prohibitive though. I live in a developing country and accessing Masterblend here is not a problem. You could contact your local agriculture officials and find out what is available there. You could experiment with fertilizers you have, but there is a science behind hydroponics. Organic manures and compost don't seem to work. Maybe aquaculture is a better suit for you.
@@TacticalGhost007 ok thanks will consider aquaponics .
@@TacticalGhost007 are you on WhatsApp will like to share with you some projects
if you dont change the water wont it rot?
Hey Denise Sim it's good to check on the levels but normally every 2 weeks I check the pH and the PPM of each plant. Make changes where needed and leave the rest to grow. I find if you can prevent light from entering your reservoir you won't have any issues with algae or rot.
the biggest cause of root rot is actually a lack of oxygen. best fix: use an aquarium air pump, hose, and airstone, to keep its roots from drowning (yes they do that lol)
What light source do you use
Mainly T5's
@@SoothingLeaf I am using a single t5 strip over a shelf full of plants roughly 10-12" wide. Is that one bulb enough? It is a Sunblaster brand. thank you
@@lindakean7392 I believe so, that should be enough. T5s are great lights. You might not be able to grow a very large plant, but leafy greens will work very well.
Can you talk about louder!?
i dont see problem in just turning up the volume since theres no noise in background
Sorry about the low volume - this was one of my earliest videos so did not have a mic at the time. Here is an updated video I have made feel is a bit more detailed and better made. ruclips.net/video/WMZz2BXMtSE/видео.html Thank you for watching!
This is asmr
@@SoothingLeaf love how you are so patient and sincere in your replies. thanks for sharing great information, i found this video really helpful!
@@alvahuang thank you for the kind words! Much appreciated, and happy to share. No expert here, just a guy with love for plants.
Firstly, you let your rockwool fall over in the basket, secondly you didnt pour the solution in the jar, then it was "one I made earlier" not a good demo
bowler8 Relax. Are you that dense that you didn’t understand the demo? It doesn’t have to be perfect. He explained it well enough.
What about all the other minerals etc that are in the soil and plants need. That's a very limited selection you are using. Which means anyone living off this produce would be deficient too.
Masterblend is a complete system of NPK and multiple trace elements.

How do I measure 2 grams? I feel dumb.
Lorinda Madore by using a gram scale. Normally digital ounce scales have a gram setting on them. You'd have to zero the scale with your measuring cup or spoon on the scale then add whatever you're measuring to get the most accurate amount.
LibertyOrDeath goto a drug dealers house lol
the nutrient bag usually says grams and in parens tells you the teaspoon equivalent.
speak up it sounds like an ASMR video *no offense*
Speak up please :)
You control your volume I have no problem hearing hin
