Complete Kratky Hydroponic Setup From Start to Finish

[@Cicatka.Michal]

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 :)

[@lidip8700]

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!

[@jenniferreynolds7082]

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.

[@jessicag630]

11:29 It's great that this video shows the setup of how to put the plants, and rockwool into the netpots from the beginning.

[@turbolag5107]

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.

[@codedesigns9284]

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]

I am completely new to this. I am trying to start with herbs first. What powdered nutrition do you recommend to use?

[@codedesigns9284]

@@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! 😀

[@jiminsealbeach4109]

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.

[@stefanvujcic6679]

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!

[@johncalvinll]

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.

[@catherineciosi147]

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

[@johncalvinll]

@@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.

[@lidip8700]

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!!

[@Investorbrock]

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

[@tonyzarzecki5408]

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.

[@22lbsboost]

how big of a container were you using? def want to try some tomatoes with this method

[@iheart3dprinting951]

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.

[@caldreamin09]

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?

[@reviewstrials6785]

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.

[@lidip8700]

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?

[@bdarmstead2]

FYI. Buy the 1.5 inch rockwool cubes for the 2 in net cup. It fits perfectly.

[@nnbodens]

Where would one buy this cube?

[@Junzar56]

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!

[@kathleencockburn2607]

When d water is drying out in d container and I have to add more water do I add plain water or do I have to mix more solution water

[@Junzar56]

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.

[@lorenawilliams4229]

Good stuff. Have you seen the pool noodle method vs Rockwell, it has to be way cheaper and you can probably also save on the neck cups too.

[@AKhan-2024]

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.

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.

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.

[@griffind262]

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

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).

[@basedpatriotLT]

Is there a limit of how much nutrient solution can the plant take? Eg - if we put double the amount you use, does that mean that lettuces will have double the amount of the "stuff" in them? Or do they only take safe amount and lettuce would not be "poison" even if we put in 10 times more of the nutrient solution? Not that we want to put that much, I just want to understand the principle (as I want my lettuce as clean as possible)
