I love that You just don't overcomplicate things. Other videos are just too overwhelming for a beginner and they discourage people from starting gardening rather then help them. Thank You and I'm sending all the best from Europe :)
Ok, I just realized Luke said 2 Tablespoons of MB, 2 Tablespoons of Ca & 1 Tablespoon of Espom Salt, which is what I followed as I bought the exact same solutions. However the instructions on the MB says Teaspoons (2-2-1). Also there's instructions on how to dissolve each one. I'm going to switch as the instructions because my strawberries, tomatoes & peppers are struggling. The are wilted & have burnt leaf edges. My lettuces are starting to burn too. Gotta love growing food.... its always a learning experience!
I had to go back in the video and check, he does say tablespoons when the package clearly says teaspoons. I looked through the comments to see if anyone else caught that.
So I've been learning about all of this over the last couple days and one of the tips have picked up on was to start seedlings in cotton balls and then when you put them into net cups use clay balls as a grow medium apparently some other content creators have had some really good luck doing it like that.
The Kratky method is a great system. The only thing I would add to Luke’s video is that if you grow with organic nutrients, such as Dutch Science, use a bubbler, because the nutrients will mould on the surface of the water when left stagnant. If using Powergrow, Miracle Grow, or other synthetics, the Kratky method Luke suggests is just fine, and saves on the power consumed by the bubbler. Always try to purchase nutrients in powdered form and not pay for the liquids. Why pay for shipped water? 👍
@@AM-hc7po This is a good question that depends on if you prefer organic nutrition, or synthetic. Herbs _typically_ need so little nutrition (compared to tomato’s, peppers, etc). If you are attempting Kratky for the first time, I would suggest Dyna-Grow (if you are in the US), and Root-Farm (if you are in Canada). I believe both are synthetic, but it may be best to learn using the synthetic as your chances of success will be much greater in a hydroponic system. Experiment later with organic nutrients, once you have a working system that grows your herbs successfully. Keep a log diary of what works, and what doesn’t, how much nutrient you use this time versus last time, bubbler versus no-bubbler, and more! The idea is to learn to have fun experimenting by growing hydroponically in the winter (or summer), or when we can’t typically grow in the ground, and have the added benefits of saving a few grocery dollars! 😀
I have been doing this for 8 years, love it!! So easy. I have had a lot of people get on to me for mixing the nutrients all together. I have never had a problem. Rock on!
Wow, a week ago i asked you about the Kratky method and now here you are. You may have already had this planned, but going to pretend it was all about me. The was my first time with rock wool. I appreciate the details about that, too. I’m trying Watercress in some big Whole Foods coffee cans. So far, they are doing okay but not thriving. I think it’s a light issue. I saw a video where a guy grew Kratke cherry tomato’s in a 55 gallon drum! I also saw a video by Kratke himself. Humble guy. Probably to only person in the world who doesn’t call it the Kratke Method. Lookin forward to the lighting vid.
This video on this method really give a solid foundation to getting started. I saw some measuring wands and terms like EC which I didnt understand and I felt like one rabbit kept leading into another but you clearly understand the target audience may actually be novice gardeners all the way around. I thought I was going to need a water ratio calculator etc and was feeling demotivated. Now I am back to inspired to get this basil going.
Just a short clear up. If something contains sulfur that does not automatically mean that it is something acidic. A lot of people share that confusion. Sulfates are neutral salts. Hidrogensulfates (Bisulfates) are acidic salts, as they still posses hydrogen (proton) to release which actually causes acidity. H in pH stands for Hydrogen, not sulfur or any other chemical element. Soluble sulfides, for example would give you very basic solutions, despite containing sulfur even hydrogensulfides that are soluble are going to be basic. Otherwise, great videos. Cheers!
After fungus gnats have drove me nuts, I'm pitching the soil out! And now I'm giving this a try. I'm determined to grow my own salad mixtures!!! Thanks Luke! You're so awesome!!
Finally got around to watching this. I've been doing Kratky for about 3 years and you were spot on Luke. I'm always surprised by the comment that say it's wrong and you have to do this or do that. This is the simplest way of growing and it's pretty hard to mess it up. Keep up the good work.
John Willis hello, I just moved in york Uk and i have a tiny back yard. I thin’ i am going to try this kratky method...do we need to change the water from the containers at times? How long can we keep the plants in the same one? Thanks
@@catherineciosi147 It totally depends on what you are growing. You don't have to "change" the water but may need to add more to the container you are using. Many things, such as lettuce, will be full grown and ready to harvest long before you need to add additional water.
Just a tip for anyone, when I first start kratky I had to much water and it would saturate my whole rockwool cube causing issues of course. Make sure that water is just at the bottom of that net cup
I started a kratky tomato plant before frost in may and was last plant to die in October and produced the best. It was started inside and was outside the entire summer, had to refill many times with water and nutrients.
I just sat down after checking my Kratky grown Micro dwarf tomatoes! Ha ha! You can put some aluminum foil on the lid it helps with reflecting bif you are growing with artificial lights. Kratky is so great indoors!
Kathleen Cockburn if you have a smaller container you will have to add nutrient solution.. but not too much. Just an inch or two at the bottom. If you fill up the container you will drown the roots. They need air.
Great Video! We are also doing an indoor garden with some static hydroponics (no bubbler). Now we look forward to an extra season in the garden, inside the house!
Love your videos, thanks so much for your content! You may consider revising the MB mixing portion of this video. They're advising making an A / B solution (to avoid nutrient lock out) then mixing them into the 5 gallon bucket.
You're correct. I also read on the MB to use Teaspoons not Tablespoons of the 2-2-1. As I've been using Tablespoons (as stated in this video), my plants are growing but they're struggling, leaves are burnt on the edges of my strawberries, tomatoes are growing by have limp curled downward leaves & limbs. Using Tablespoons vs Teaspoons is making the solution 3x stronger then the instructions. How much do you use?
If you can get 1.5", you'll have a very snug fit without a lot of waste, since the face's diagonal will be 2.12", as opposed to 2.82" on the 2" cubes or (only) 1.41" on the 1" cubes.
Thanks so much Luke, This is a really great video. My husband and I sat here and watched the entire thing lol, you really did a great job and gave a lot of information. Thank you so much for sharing, I really appreciate it. Keep on rockin' on and growing like you do! I really enjoy watching your channel!
I am so glad you are explaining the Kratky Method of hydroponics. I bought a 4 cell machine first and then learned about Kratky. With Kratky, we have to learn our chemistry--the easy way. (And to learn Liter to ounce conversion along the way.)
I would love to hear your recommendations for setting up an entirely diy hydroponics system using recycled components like plastic 2 liter bottles and things like that.
This video is a great place to start. I'm starting my seeds tomorrow in a plastic deli containers. Going to plant in Mason jars and yogurt cups. I bought hydroponic fertilizer on amazon. That was the most expensive thing. $19. I ordered grow big instead of masterblend and I'm going to use coconut hulls for the medium instead of rock wool. It was on clearance on amazon for $3 for enough to make 8 quarts. Cheaper than peat pellets. ruclips.net/video/A-DNrQoKcnc/видео.html
PLEASE leave a link to the next video in this series! i really dont want to scroll through tons of videos to try to find it. And by the way if you are diligent about going back and retroactively leaving links in past videos it will GREATLY increase your audience base.
Can you tell a difference between the taste of Kratky method grown tomatoes vs Soil grown tomatoes? I love your channel mainly because of your detailed explanations & honest opinions.
Tips for beginners. 1. Remember this isn't as easy as it sounds. Just like anything worth doing. Don't just set it and forget it. Examine it just like Kratky did. 2. If you are putting this outside, protect the plastic from UV, preferably something white/reflective so water doesn't heat up in summer. Aluminium foil works well. Also these containers are not food grade. If possible line it with something that is. I know you're not gonna eat the roots. 3. Different stages of plants need different amount of nutrition. 4. You will add more nutrients/water. The water will evaporate/be used up depending on the environment. 5. Before adding more nutrients remember that some nutrients might have precipitated to the bottom. Try to mix it up first before adding more . 6. Pay attention to the plants. It will show deficiencies when you need to add more. If you look up the symptoms you will be more able to treat it. 7. Remember that long term health effects have not yet been recorded. Many of the formulas from the most reputable sources come with labels that say not to allow animals to feed on the leaves grown this way. So just be careful, buy direct from companies that have been doing this for decades. That is all I have time for. Good Luck.
@Op Hs Where did I say kratky system was bad? And which one of my tips do you think is trolling? hahaa If you want to actually discuss about methods that'd be great. But it seems like you're trolling :) Have a good day
So simple, I love it. I'm a little confused, though. I've read somewhere, full nutrients shouldn't be applied to seedlings, instead, use just plain water until they grow bigger.
This will be great for my spring ladies and all of my other food and flower babies 💚 I still think the core gardening method is the best thing I've ever learned from your channel, but this video is seriously a solid second place. I'd also like to say that the grab bag sale was amazing and I was extremely happy with everything that I received, and I truly appreciate everything that you and your wife do for all of us plant freaks! Wishing you and your family a happy and prosperous 2020! 💚
I think it's awesome and really interesting and great as a hobby. And people have different reasons for growing, but if one is growing for food as a way to save money. I do have one concern or thought. Have you calculated the total cost of the products used and electricity. I'm wondering if it's actually economical compared to just buying it. Again, this is separate for doing it for health or hobby reasons.
Great video, thanks. I'm just planning to start when I move into my new house, so this gives me a lot of great info. The only thing I'm looking for is lighting information. Any suggestions as to what's preferred by people? I suspect some sort of multicolor LED fixture on a timer.
Thanks for the video. I'm just a beginner and have purchased the MasterBlend kit. It shows on the label to use 2 tsp (teaspoons) of each MasterBlend and calcium nitrate and 1.5 - 2.0 tsp (teaspoons) of magnesium sulfate. You instruct to use tablespoons (tbs) of the ingredients. That is 3 times the recommended amount. Do you get better results using the higher concentrations?
I loved your video on the Kratky Method, I am wondering how often you add nutrients to your water. Since I am not topping off the water, I thought maybe the nutrients would get too strong if I add every 2 weeks as suggested on my Masterblend package.
Question- I put three lettuce seeds in each rock wool cube- wow they all germinated Should I now just snip off the two smallest before transplanting into the hydroponic area ?
@@warrenschwartz5653 Or free at your local grocery store bakery department, icing buckets. They love giving them away, saves them the hassle of throwing them in the dumpster : )
Ha! I was JUST going to ask about lighting when you said you were going to talk about lighting in a future episode! Looking forward to that! The other thing I'd like to know about is algae growth. Like, how pond water gets that gross smell and thickens up with a green-brown nasty... Does it happen with this method? If so, how do you suppress that? If not, is there a way to explain why in layman's terms? I've never tried growing hydroponically and *might* try it. Thanks for your input and advice! Love the channel! :)
When I started I had the same question on the algae. The dark containers prevents algae from growing. You'll see a lot of people painted their containers black. On hot places, they insulate their containers. I can't answer you about lighting because I did a south facing window sill hydro. All I heard is it has to be at least 1000 lumen and 6500K color for greens. Here's my simple setup if you like to see it. I used pvc fence post and fruit juice containers. ruclips.net/video/vD5cLn3zzis/видео.html
I got started doing using this method with you guys and I love it. One question, I’m looking for a container that isn’t as deep as the HDX containers but is still long. Do you have any suggestions? Grow big!
I'm just discovering the Kratky method but I have a question - instead of having a large container to hold nutrients for the life of the plant why can't you use a smaller container and top up the nutrient liquid from time to time?
It is possible, but most prefer the "set and forget" method. And unless you are willing to check the level or have a method of checking the water daily, certain plants will uptake all the nutrients relatively fast. Some people do leafy greens in mason jars and plastic coffee contains with no problem. Check out RUclipsrs Khang Starr and Tales From the Mutiny.
Very helpful. Two questions: is a half-gallon Mason jar large enough for a head of lettuce or herbs like basil? And how can I do this same thing organically, instead? I'm new to all of this and haven't had luck finding organic nutrients so far. Thanks!
Large mason jars will work great for those plants, as will a pasta sauce jar. Be careful to get net cups with wide rims as not all net cups will fit jars very well.
@@JimmyBHarvests After a few harvests now, I can tell you the size that I have is likely better (IMHO) than a pasta-sized jar as I have to refill the jars to get the level up for the water roots every few days. The problem that I think I ran into on a few of them is that you're not supposed to get the aerial roots wet at all, but as I've just been adding water from the top, I've been getting them wet as I add nutrient water and I've rotted a few of them. I need to devise some way to top up the water and not get those roots wet.
You are right! it is too much. Instructions at 5:55 for 2 teaspoon. per 5 gal lettuce blend: 10 grams Masterblend 4-18-38 10 grams Calcium Nitrate 5 grams Magnesium Sulfate tomato/pepper blend: 12 grams Masterblend 4-18-38 12 grams Calcium Nitrate 6 grams Magnesium Sulfate
I have seen videos that say if you don’t mix them separately first and let them dissolve completely you could have a lockout where the plants doesn’t get the nutrients. Have you had any issues with this?
Hi sir my name is Hussain from uk thank you for your wonderful videos .i like to know if I can use this system to grow pumpkins and water melons my daughters favourite fruit and if can make video about it explaining how much of scoops of nutrition we need to add. Also can add the links were I can purchase all the three items. Thank you Kind regards Hussain.
Great video and cleary explained. Where I live a lot of people use BPA and phalate free plastic containers for hydroponics. Is this a concern in the USA as I see most people use normal storage containers there?
What PH are you targeting and what is the PH of your water to start with? You are assuming that everyone has the same water PH to start with which isn't true. It could be neutral to acidic rain water, or very calcium heavy hard well water.
The master blend should be mixed with the epsom salt first because the calcium nitrate won’t mix into solution properly you might notice that it won’t dissolve when mixing it will hinder growth
Would you be able to get away with radishes and/or carrots along with lettuce? Just thinking over other vegetables that could be grown with this Kratky method. Going to try it out this week, very excited!
From what I've read, no. Most regular fertilizers contain stuff like urea which can't be broken down in water and wind up burning plant roots. But I may be wrong.
I would respectfully argue the best methodology is let nature do more of the work. Simply make a "cartridge " by placing rockwoll in cup, plant the seed, cover the top with aluminum foil, then make a small pencil sized hole in the foil. When it's time just submerge the cup in water then place it in its Kratky home. The foil prevents mold and fungus growth. As the plant grows it will find that whole and rip it larger as needed.
At what point are you moving seedlings to hydroponic bin? Are you waiting to see roots out the bottom? Have not seen a ton of info on this. Look forward to more videos on your setup and progress.
Luke where did you purchase your tubs do I need to purchase the same kind of tubs or can I just buy any o tub that's about that same size to start that project and does the water have to be warm or can It be cold
Hello and thank you for this video, that show how to do from start so that’s really helpful and beneficial. Could you please write the name of the method you are speaking about to start seedling?
Great video. Can you put more than (2) 2" net cups in the smaller 5 or 6 gallon container? I'm thinking of using (6) to start, then transfer them to other containers as they get bigger.
you talk about putting your seedlings in the cups. what I haven't found is where you start them? I have 3" cups. will those work? I have a 17 gallon container so I"ll need 3 5 gallon buckets of solution plus enough for 2 gallons?
Thanks for this video. Please can you guide me on the following. I want to try this method growing a few herbs but outside. Will this work outdoors? Also how often should I change the water? Do I also need to top up the solution during a single harvest?
great video, one question - you didn’t check ph level after adding epsom salt. is it not that crucial or did you forget to check ph level or does those exact measurements you added create the perfect ph level? thank you for your expertise
Putting those in the garden and knowing the solution will evaporate over time, when it becomes low do you top it off with new solution? or will evaporation make it concentrated that you'd only have to top it off with water?
is there a list that is around that shows how big a pot to use for different plants, ie: tomatoes, or lettuce. I want to try this, but how many lettuce plants can I grow in a 5 gallon bucket. thanks
I took a Kratke method class several weeks ago and they said you should use food grade. Glass jars, of course, wouldn’t be a problem but they also said that Home Depot buckets are food grade.
Hello and thank you. What type of summer squash do you plant in this system? I have been growing indoors with four tower gardens for about 2.5 years, but I'm tired of the noise. I've only been successful with anything but greens and herbs. Since my diet is predominantly vegetables, I'd like to add something with a bit more body, like summer squash and green beans. Also, I didn't see a lighting video for this. Did you make one? Anyway, I hope you see this and have time to answer. Thanks for these great videos.
When you've harvested your plants and it's time to start over, is it okay to keep the solution that's in the container and just top it up or is it advisable to dump it and start fresh? Are the roots absorbing the nutrients from the bulk water or only what they "drink"?
If you sure that river is not contaminated by anything upstream the river I wouldn't see any problem, since moving water is generally cleaner than static water(ponds). It might have slightly higher pH if its mountain river because it dissolves minerals on the way downhill. But still I would give it a try, don't fear to experiment a little :)
Can I grow zucchini and sunset squash with the kratky method? If you have a large enough container and enough nutes? I've seen people who say you can't, then I've seen people do it and say it can be done. Opinions? Real experiences?

That is all I have time for. Good Luck.
@Op Hs Where did I say kratky system was bad? And which one of my tips do you think is trolling? hahaa If you want to actually discuss about methods that'd be great. But it seems like you're trolling :) Have a good day
Good tips for anyone to remember! Sometimes I forget the simple stuff. 🙏
@@marciamarcia7449 Haha what? Fear mongering over a hobby? First world problems.
So simple, I love it. I'm a little confused, though. I've read somewhere, full nutrients shouldn't be applied to seedlings, instead, use just plain water until they grow bigger.
What temperature range should I plan for the room to be for growing?
This will be great for my spring ladies and all of my other food and flower babies 💚 I still think the core gardening method is the best thing I've ever learned from your channel, but this video is seriously a solid second place. I'd also like to say that the grab bag sale was amazing and I was extremely happy with everything that I received, and I truly appreciate everything that you and your wife do for all of us plant freaks! Wishing you and your family a happy and prosperous 2020! 💚
Nice video but I didn’t see anything about getting the plants started I never heard of rock wall where do I find the rest of that information?
For the rockwool you should get a pipe and sharpen the end to make a plug cutter. It would make rockwool cutting very quick and easy.
Great job on this video my friend! I look forward to seeing you soon!
I think it's awesome and really interesting and great as a hobby. And people have different reasons for growing, but if one is growing for food as a way to save money. I do have one concern or thought.
Have you calculated the total cost of the products used and electricity. I'm wondering if it's actually economical compared to just buying it. Again, this is separate for doing it for health or hobby reasons.
Thanks .... Easy explanations -- much appreciated.
Great video, thanks. I'm just planning to start when I move into my new house, so this gives me a lot of great info. The only thing I'm looking for is lighting information. Any suggestions as to what's preferred by people? I suspect some sort of multicolor LED fixture on a timer.
Thank you for more information on kracy growing method.
Thanks for the video. I'm just a beginner and have purchased the MasterBlend kit. It shows on the label to use 2 tsp (teaspoons) of each MasterBlend and calcium nitrate and 1.5 - 2.0 tsp (teaspoons) of magnesium sulfate. You instruct to use tablespoons (tbs) of the ingredients. That is 3 times the recommended amount. Do you get better results using the higher concentrations?
Probably not, just fried plants😢
This video is awesome! Okay, but where do I start? Where do I get all the necessary equipment and ingredients? Is there a written tutorial with links?
I loved your video on the Kratky Method, I am wondering how often you add nutrients to your water. Since I am not topping off the water, I thought maybe the nutrients would get too strong if I add every 2 weeks as suggested on my Masterblend package.
Question- I put three lettuce seeds in each rock wool cube- wow they all germinated
Should I now just snip off the two smallest before transplanting into the hydroponic area ?
Thanks MI. One query: are those plastic tubs chemically safe for food? If so, then where did you obtain them?
I doubt those are food grade. If you want a food grade container, get a food grade, (white) 5 gallon bucket from your big box store.
@@warrenschwartz5653 Good advice. It seems to me that there would be a market amongst the health conscious and preppers, such as I.
@@warrenschwartz5653 Or free at your local grocery store bakery department, icing buckets. They love giving them away, saves them the hassle of throwing them in the dumpster : )
Thanks. Very informative. It seems like most of these videos just kind of make a quick pass over the fertilizer info.
Have you ever tried planting the seeds directly in the kratky system?
There is a RUclips video where someone uses seeds.
can i use this system in an outdoor hoop house
Yes
Where do I purchase the rock stuff that germinates the seed? I hope you have a list of all ingredients, thanks!
Ha! I was JUST going to ask about lighting when you said you were going to talk about lighting in a future episode! Looking forward to that! The other thing I'd like to know about is algae growth. Like, how pond water gets that gross smell and thickens up with a green-brown nasty... Does it happen with this method? If so, how do you suppress that? If not, is there a way to explain why in layman's terms? I've never tried growing hydroponically and *might* try it. Thanks for your input and advice! Love the channel! :)
When I started I had the same question on the algae. The dark containers prevents algae from growing. You'll see a lot of people painted their containers black. On hot places, they insulate their containers. I can't answer you about lighting because I did a south facing window sill hydro. All I heard is it has to be at least 1000 lumen and 6500K color for greens. Here's my simple setup if you like to see it. I used pvc fence post and fruit juice containers. ruclips.net/video/vD5cLn3zzis/видео.html
So if he's trying to grow summer squash i'm guessing he has to manually pollenate the flowers?
I got started doing using this method with you guys and I love it. One question, I’m looking for a container that isn’t as deep as the HDX containers but is still long. Do you have any suggestions? Grow big!
Try IKEA or Costco
I've used plastic wash basins before. They are around 6 inches tall. You can find them in most grocery stores
Under bed bins you still get the long but they are much less deep.
What about under bed storage tubs? They have some a little deeper but they are very long
@@stephaniearends1309 That is exactly what I was looking for. Thank you.
Have you actually grown squash this way? They sprawl so much I’m intrigued.
I'm just discovering the Kratky method but I have a question - instead of having a large container to hold nutrients for the life of the plant why can't you use a smaller container and top up the nutrient liquid from time to time?
It is possible, but most prefer the "set and forget" method. And unless you are willing to check the level or have a method of checking the water daily, certain plants will uptake all the nutrients relatively fast. Some people do leafy greens in mason jars and plastic coffee contains with no problem. Check out RUclipsrs Khang Starr and Tales From the Mutiny.
@@dwainmcwilliams2043 thanks for responding, will check out those videos.
Very helpful. Two questions: is a half-gallon Mason jar large enough for a head of lettuce or herbs like basil? And how can I do this same thing organically, instead? I'm new to all of this and haven't had luck finding organic nutrients so far. Thanks!
Large mason jars will work great for those plants, as will a pasta sauce jar. Be careful to get net cups with wide rims as not all net cups will fit jars very well.
@@JimmyBHarvests After a few harvests now, I can tell you the size that I have is likely better (IMHO) than a pasta-sized jar as I have to refill the jars to get the level up for the water roots every few days. The problem that I think I ran into on a few of them is that you're not supposed to get the aerial roots wet at all, but as I've just been adding water from the top, I've been getting them wet as I add nutrient water and I've rotted a few of them. I need to devise some way to top up the water and not get those roots wet.
You said 2 table spoon the package calls for 2 teaspoon so do you add more?
You are right! it is too much. Instructions at 5:55 for 2 teaspoon.
per 5 gal
lettuce blend:
10 grams Masterblend 4-18-38
10 grams Calcium Nitrate
5 grams Magnesium Sulfate
tomato/pepper blend:
12 grams Masterblend 4-18-38
12 grams Calcium Nitrate
6 grams Magnesium Sulfate
I have seen videos that say if you don’t mix them separately first and let them dissolve completely you could have a lockout where the plants doesn’t get the nutrients. Have you had any issues with this?
Awesome, i'm going to give this a try.
Hi sir my name is Hussain from uk thank you for your wonderful videos .i like to know if I can use this system to grow pumpkins and water melons my daughters favourite fruit and if can make video about it explaining how much of scoops of nutrition we need to add. Also can add the links were I can purchase all the three items.
Thank you
Kind regards Hussain.
Great video and cleary explained. Where I live a lot of people use BPA and phalate free plastic containers for hydroponics. Is this a concern in the USA as I see most people use normal storage containers there?
BPA is banned here in the US
What PH are you targeting and what is the PH of your water to start with? You are assuming that everyone has the same water PH to start with which isn't true. It could be neutral to acidic rain water, or very calcium heavy hard well water.
The master blend should be mixed with the epsom salt first because the calcium nitrate won’t mix into solution properly you might notice that it won’t dissolve when mixing it will hinder growth
Yea you shouldn’t do that because the calcium nitrate won’t blend into the water properly
I thought the Masterblend direction said, 2 tsp per 5 gallons. Am I read it wrong?
Yes, it does
I use General Hydroponics Flora set plus Liquid Seaweed.
great video, just one question, how much water do you ideally need per lettuce plant?
what about lighting for the kratke method
Would you be able to get away with radishes and/or carrots along with lettuce? Just thinking over other vegetables that could be grown with this Kratky method. Going to try it out this week, very excited!
Saved video it‘a what I was looking for. Thanks
Can I use regular organic liquid fertilizer for a smaller hydroponic system?
From what I've read, no. Most regular fertilizers contain stuff like urea which can't be broken down in water and wind up burning plant roots. But I may be wrong.
I would respectfully argue the best methodology is let nature do more of the work. Simply make a "cartridge " by placing rockwoll in cup, plant the seed, cover the top with aluminum foil, then make a small pencil sized hole in the foil. When it's time just submerge the cup in water then place it in its Kratky home. The foil prevents mold and fungus growth. As the plant grows it will find that whole and rip it larger as needed.
Question: I am just getting started. If I use 18 gallon totes. How many tomato, cucumber, bell pepper and summer squash plants are optimal?
Rick S.
At what point are you moving seedlings to hydroponic bin? Are you waiting to see roots out the bottom? Have not seen a ton of info on this. Look forward to more videos on your setup and progress.
Luke where did you purchase your tubs do I need to purchase the same kind of tubs or can I just buy any o tub that's about that same size to start that project and does the water have to be warm or can It be cold
I got my tubs at lowes
Costco has them on sale
Hello and thank you for this video, that show how to do from start so that’s really helpful and beneficial. Could you please write the name of the method you are speaking about to start seedling?
Good video! I was told that you should mix the fertilizers separately so there is no nutrition lock out, is that not necessary? Thanks!
Great video. Can you put more than (2) 2" net cups in the smaller 5 or 6 gallon container? I'm thinking of using (6) to start, then transfer them to other containers as they get bigger.
What can I replace that master blend with. Such things are not available in my end of the world.
you talk about putting your seedlings in the cups. what I haven't found is where you start them? I have 3" cups. will those work? I have a 17 gallon container so I"ll need 3 5 gallon buckets of solution plus enough for 2 gallons?
Great video, earned a new sub🤗
Where do you get the seed cubes from?
Thanks for this video. Please can you guide me on the following. I want to try this method growing a few herbs but outside. Will this work outdoors? Also how often should I change the water? Do I also need to top up the solution during a single harvest?
Have you watched any of Mike VanDuzz's videos? He uses pool noodles instead of Net Cups and rockwool. Much cheaper and easier.
great video, one question - you didn’t check ph level after adding epsom salt. is it not that crucial or did you forget to check ph level or does those exact measurements you added create the perfect ph level? thank you for your expertise
So . . .. just WHERE do you get your products from to fertilize the water? Thanks . .. .
Putting those in the garden and knowing the solution will evaporate over time, when it becomes low do you top it off with new solution? or will evaporation make it concentrated that you'd only have to top it off with water?
is there a list that is around that shows how big a pot to use for different plants, ie: tomatoes, or lettuce. I want to try this, but how many lettuce plants can I grow in a 5 gallon bucket. thanks
Great video. Just one query, should your containers be food grade? Leaching from plastic could make its way into the solution,
I took a Kratke method class several weeks ago and they said you should use food grade. Glass jars, of course, wouldn’t be a problem but they also said that Home Depot buckets are food grade.
Always fun haven a grow method named after you :P
on my german channel i use also masterblend.this is very easy .
Great video! One question: is there any risk of light leak with the yellow lids, which could lead to algae growth in the reservoir?
That's a good question. If I was using these, I'd paint the lids black.
Hello and thank you. What type of summer squash do you plant in this system? I have been growing indoors with four tower gardens for about 2.5 years, but I'm tired of the noise. I've only been successful with anything but greens and herbs. Since my diet is predominantly vegetables, I'd like to add something with a bit more body, like summer squash and green beans. Also, I didn't see a lighting video for this. Did you make one? Anyway, I hope you see this and have time to answer. Thanks for these great videos.
When you've harvested your plants and it's time to start over, is it okay to keep the solution that's in the container and just top it up or is it advisable to dump it and start fresh? Are the roots absorbing the nutrients from the bulk water or only what they "drink"?
Great video !!!!
What grow lights are best for tomatoes and peppers?
If I wanted to use river or creek water, would I need to filter it first for this Kratky system, or can I use it as is?
If you sure that river is not contaminated by anything upstream the river I wouldn't see any problem, since moving water is generally cleaner than static water(ponds). It might have slightly higher pH if its mountain river because it dissolves minerals on the way downhill. But still I would give it a try, don't fear to experiment a little :)
Can I grow zucchini and sunset squash with the kratky method? If you have a large enough container and enough nutes? I've seen people who say you can't, then I've seen people do it and say it can be done. Opinions? Real experiences?
