I partially buried my Kratky Tote and insulated the exposed parts. That kept the Nutes cooler and evaporation down.
Thank you for this!
Packed with valuable information and straight to the point. Incredible video!!!
Thank you for the download and the vlog...I'm an octogenerian and I'm very excited to find a "new" way to garden 😊
Always excited when I find another Kratky grower! Thanks for sharing
You and me both! Thanks for being here 😊
Superb. Precise n relevant information. To d point n lucid clear. Thx 👍🙏
Something I’ve learned, submersible, UV lights. They work wonders to eliminate the growth of algae in your reservoir. Mine runs for an hour per day and I have no algae with clear container
Wow really!? Thank you so much for the info, I'm going to give it a shot asap.
...you shouldn't have algae growing at all if the submersible is dark. And UV lights kill EVERYTHING including good bacteria...so...
This is a great video. Very concise. I’ve been maximizing my light recently, by adding dozens of 32 and 64 ounce ball jars.
Excellent video! Thank you!
Glad you liked it!
Very useful tips, thank you mate.
Thank you greatly friend!
Wonderful spot-on video. I would love to have some help on nutrient concentration on Kratky gardens vs Aerogardens for tomatoes and for greens. And since you said to cut circulating system solutions in half, all I would need to know is the ppm concentrations in circulating systems for tomatoes and other fruiters and also for nonfruiting plants. Thanks from a brand new subscriber.
Well done video. Thanks for the tips.
Thank you so much! And you are so welcome 🙏
Great tips for beginners
Thank you so much for saying so!
Great info I needed to tweak a few things like. Less water at the end when flowering started
So glad I could help!! That is by far the most common problem people run into. I know I did. 😀
Very nice sets of tips. I've learned these the hard way, but I hope anyone watching this takes in all of this excellent information prior to getting into this amazing hobby. It's incredibly fulfilling and exciting. Thanks for sharing!
Thank YOU for the excellent comment fellow Hydro Farmer!! 😀 I couldn't agree more!
Again, your visuals are simple and clear.
1. Half of recommended concentration when it comes to nutrients (750 ppm if 1500 ppm is recommended)
2. Add 10mL of 3% H2O2 per gallon
3. Wrong size container
4. Always keep grow light 12" away
5. Prevent algae by growing something that grows fast
Thanks!!
You bet!
Much appreciate your presentation! Myself just starting up and got a few tomato plants in roughly 45 L black, double walled (for temp control) pots outside. However, over the past five weeks I’ve been fighting the pH and EC values like crazy. They keep exploding on me. An addition to that not getting much hydration and the roots are not coming out of the cocos. I’d really appreciate any advice you might have!?
Thanks for this video. 5:07 Very easy to follow for a beginner. I also appreciate your humble response to patronizing comments, and I learned a lot more by reading them. You've got a new subscriber! Also, can you please link any other videos you refer us to in your description, as they don't show up in the video when I'm watching on my TV. Thanks 🙏
Absolutely! Thank you so much for the subscription and kind words!:)
Great great, thank you! New sub and ready to grow
You are so welcome! Thank YOU, Really glad you're here :)
When using Hydrogen peroxide i dont recommend using the stuff you buy at the store it has additional chemical stabilizers in You can get FOOD GRADE peroxide but its gonna need to be diluted quite a bit its like 35% and should only be added to distilled water before using .😊
Food grade is available in different strengths, and 3% is easy to find.
Hi: I grow hydroponic strawberries. Because they're a long term crop, they easily get root rot. I've found that colloidal silver, 3-5ml per gal, helps a lot. I also use air stones--actually mandatory--to minimize root rot. I know this isn't Kratky, but a hybrid DW culture. There is also an organic fungicide called bacillus amyloliquefaciens which helps with root rot. Same dosing as Colloidal silver. This is most useful in the heat of summer outdoors, where I grow day neutral strawberries in DW hydroponics. I also use some H2O2.
This is excellent advice thank you so much! 🙏
Kenneth, mind if I pick your brains first thing in the morning? Well, it is here in Australia. Q1 - being a long term crop, what size bucket do you use for them?Q2, And when "buckets" are talked of, do they have to be deep, or just shallow and wide? Q3 (the last I promise) what power pump for said buckets? Is there a ratio, Lt to watts of power for the air stone. And thanks in advance.
@@leoandrews169610 gallon tubs are better. Buckets need to be refilled more often
Hey, for the way adding hdrogen peroxide 10ml per gallon, does it mean around 2.5ml per liter?
I've been growing winter greens in the basement kratky and regular soil style for quite a few years. Mostly lettuces, bok choy, arugala. Now I only use kratky for microgreens unless I use large, at least 1/2 gallon, containers for kratky growing. I have found that using quart containers or smaller means constant monitoring of the water after plants and roots start to take off and begin consuming higher quantities of water. Since the plants grow at different rates I have to lift or check each container daily to make sure there is enough water and not too much when I add new water. This is time consuming.. Also need to monitor for algae and root rot and ppm.
With my soil planted greens, I use 4" pots in a 10x20 tray and water 8 or more at once, letting them drink as they please. So much easier. No algae, root rot or babying. I also like that I can use organic fertilizers (I use Plant Food Hero mostly) in soil, whereas you can't use organic fertiiizers in kratky or hydroponics.
Thank you for your input. The idea of the Kratky method is to make sure your container is the proper size to NEVER have to fill or top off the plants. It's suppose to be passive gardening unless you do it wrong. Which is why I make these videos. You will ONLY get root rot if you water temperature is to high, like if it's in direct sunlight. That's why I'd recommend grow lights, and temperature monitoring 👌 you can also get or make organic hydroponic nutrients, but the usda doesn't consider hydroponics organic because they say it has to be in soil to be organic, I don't completely agree with that but whatever. 🤙
Thank you, I definitely have a root rot problem with some of my setups. If I use an air stone (not Kratky, I know), will that tend to prevent root rot?
so the root rot makes it hard for the plant to absorb oxygen, so getting as much oxygen to the roots as possible would certainly help, but also be sure to check your water temp, if it get's above 85 degrees F, that's prime root rot conditions. Hope this helps!!
Very nicely explained in less but effective words. I have 2 questions
1. What if i keep a hole on the surface, covered always but to open it daily for a few minutes for air to enter & circulation, stir the water without disturbing the root system?
2. Algae is mostly unavoidable, but does it create any harm for the roots & plants?
It's not unavoidable and yes, it steals the nutrients from the plant, you don't need competition and fertilizer is expensive
Thank you so much for this! Would adding snails to my clear mason jars (kratky/herbs) work in combating algae?
That is a very interested idea! I think you should try for sure. My only concern would be that they might eat the roots too. Give it a shot though and let me know how it goes.
@@humblegrowth Thank you!
Thumbs up for your baby!
wouldnt 10-20cm from small LED (ive got 23w) light be okay for herbs?
You talked about nutrients concentration ppm. What part per million exactly are you testing and with what testing product? Thanks a lot.
So sorry for the untimely response. So I use a Ec meter amzn.to/3j0GKoR to measure my nutrients. It won't tell you what nutrients are in there but it will tell you how many overall czcams.com/video/udR10DLpPZY/video.html For clear kratky gardens I use the nutrients that came with my tower garden, but generally I use these for most of my hydro setups amzn.to/3kNsRKU and these for the more sensitive setups. amzn.to/3Hy1LjS but there are so many choices in brands, I'm not sure you can go wrong.
How much water is required for 1 pound of cucumbers?
Notes for myself
Blocking lights is the best way to keep algae
Root rot might be because there's no air for the roots thats why we would use hydrogen peroxide
Thank you, finally getting ready to just start the mason jars and items for set up. Is the peroxide you mention possibly the food grade? I have seen people adding drops of this type of peroxide to their drinking water and believe it is the H202 you meant?
New subscriber, keep up the nice videos.
The Hydrogen Peroxide I mention is only %3, food grade H202 (thank you :) is usually much higher in strength like %35 and thank you so much for the sub!! glad you're here :)
@@humblegrowth Thank you, for answering. I have it in my cart for delivery going to make my purchase as soon as I find a spot out of my son’s reach or sight. lol
@@SouthFloridaSunshine lol my 2 yr old son has been the executioner of many plants in my garden. I try to make it a learning experience for everyone, but mostly just for me to keep them out of reach 🤣
Can you only add the H2O2 at the beginning of the setup, or is it something that can be added say weekly, bi weekly, monthly?
Great question!!! You can, and I recommend adding the H2o2 every week to your setup. As the level drops and the nutrients concentrate you should adjust the amount appropriately. I Hope this helps :)
@@humblegrowth awesome, thank you so much.
I've been doing this wrong and changing out the nutes completely/adjusting ph once a week.
I used the brown mason jars and they worked great in the beginning in preventing algae, but 3 months later they have algae even though there was no light coming from the top...
Good to know, thank you for the experience 🙏
What you're seeming to suggest is that somehow your alegea is violating the laws od thermo dynamics.
It may not have seemed significant to you, but there was still probably a tiny amount if light filtering through your medium.
Algea is bad because it competes with plant roots, but if it's growing so slowly it's ultimately toothless.
You say it's important to calculate the container size. How do I do this? I find it hard to find information on this. I want to grow lettuce but I don't know what size container I should use.
It is so hard to find good reliable sources for information like this. It's all about the root size, lettuce and other leafy greens grow fast and are perfect for the large Mason jar Kratky setup, also herbs in the mint family (pretty much all popular herbs) have shallow root systems so they can handle smaller container too. Larger plants like, tomatoes, peppers, cucumbers etc... should be in a much larger container like a 5gallon. You can always start these large plants in a jar then move them into a lather setup once the jar has become too small.
thanks. starting with 750ppm but when you add the rest?
When the water drops the concentration will raise so I understand it
Wouldn't nutrient levels actually go down as the plants consume them at some period of time? Sorry, I'm a beginner and am learning this. Your information is very informative. Thank you.
Hey no worries. Some of the nutrients do go down any get absorbed, but the heavier nutrients end up concentrating at the bottom. Similar to when you reduce something on your stove like soup, you concentrate the flavor by boiling out the water, leaving the spices and seasoning behind. The water in jar is absorbed leaving the heavy nutrients to concentrate in less and less water. Hope this helps. 🤙
@@humblegrowth Makes perfect sense. I appreciate your reply. I'm a new subscriber. Thanks.
Just switched a plant to dwc from kratky could have used this video before and probably not have switched. Oh well, now I know. And knowing is half the battle!
Exactly! Thanks for the comment Azrael :)
keeps us updated abot your electric bill.
Yep - loving the "tad of hydrogen peroxide" Idea.
sounds like a $1 air stone and a $10 air pump will just save you more time and energy then anything else.
that was my experience anyway... $11 and every kratky problem i used to get not only stopped
but plants grew bigger.
Mixing measuring systems is confusing. ML to GALLON?
How about OUNCES per gallon?
In the USA we use ounces and gallons, not the metric stuff.
As the plant uses water it ALSO uses those nutrients therefore your nutrient concentration will not be exceedingly high as the water level drops.
BIG concern is salt buildup.
Best to dump the water out when low and replenish with fresh nutrients and clean water.
Black and dark pots get really HOT in the summer sun. So hot that it kills the roots on the sun facing side of the pot.
At least with soil filled ones anyway.
And then you might want to consider mosquitoes if your pot is not sealed properly and it outside.
What are your measurements for a 5 gallon bucket with Kratky method?
I’ve got a thousand questions as I’m just getting started do you have a website or email address?
Why no refill?
Not my rules lol. Its passive hydro, you don't have to do anything after setup.
im new to this first time and myh leaves are yellowing
I have yellow leaves too. Hoping for a hint!
Brilliant tips. Thanks for the knowledge.
Glad it was helpful!
Have you checked out my kratky invention
Haven't yet. Send it over and I'm happy to check it out!
Love ur channel bro not sure why u don't have more followers. Looks like u use that peroxide on ur teeth too lol. They nice and white.
I appreciate that! 😂🙏
Uh... so you're using agricultural hydrogen peroxide or that antiseptic version that is full of things like silver & other shelf-life-extending -solutions... Just saying if you skin begins turning blue...jkjk
It's not silver stabilized h202. Thank you for your comment and concerns.
@@humblegrowth They use silver & other ingredients to keep the self-life extended on antiseptic peroxide where the ag version expires far sooner. You can't just say it doesn't contain silver.
@@SlackerU I'm having a hard time finding any real information about this. Would you mind linking up the sources in the comment chain here for people, if you have the time? I love to share new information I discover from the comments in follow-up videos, I just want everything I share to be backed up with credible resources. Maybe I just searched for the wrong thing. I would love to be able to warn people that there is silver in 3% hydrogen peroxide, I just can't find that information anywhere. Thank you so much for back and forth, we can all learn from each other if we're willing to be humble. :)
@@humblegrowth Sorry, the search term is 'food grade' peroxide & not 'ag'. The companies aren't legally required to list what they use to extend shelf-life & improve medical antiseptic properties of peroxide. You want to be using "food-grade" to ensure it doesn't contain this legally-not-listed medical-related-ingredients used to improver antiseptic properties for residential products that are often misused by non-doctors.
@@humblegrowth See below.
Why would you tell people to put there lights 12" away when you have no idea what light they even have?
Because I never suggest how long they should be on. 12 inches is safe for just about any plans up to 12-1300 Umols. thanks for the concern Mr Bongholio. :)
@@humblegrowth 18 hours for veg, 12 hours for flower is standard. The amount of hours has nothing to do with killing your plants with too much light. I would love to see your plants in your next video. - The_Real_Bongholio.
@@bongholio unfortunately all of my plants froze a few weeks ago, when my heater popped a breaker. You are more than welcome to watch my older videos (this channel is only a few months old) to see my setup. I probably show it a bit in my led lighting 101 video too. czcams.com/video/AYoDQdXQuMw/video.html
also, If you would like to use the 18-12 growth cycle then it should be up to you to figure out the ppfd at 12 inches that your plants would need. (I can't do all the work lol)
Thank you for your input, I always appreciate the engagement. 🤙
