Hi dr! I just stumbled upon your channel as I’m looking into the Kratky method. This video really highlights your teaching skills and practical advice for anyone looking to emulate it. Please continue inventing and sharing your insights as future audiences continue to adapt your way of agriculture.

So wholesome! ❤

This video is amazing

Nice to see you are still creating and having fun.

👍

Congrats on your 50th video!! Absolutely love what you do. Thanks again!

Dr. Kratky, greetings from Brazil. Here, specifically for mangos, a picker was developed using a metal rim with a V shaped blade fixed to it by a screw, on the opposite side of the pole, used to cut the peduncle. The bag has velcro on the edges so it can easily be removed to transport the harvest. I wish I could show you a picture... Hope it gives you some ideas!

🙏

Clever and useful DIY tool!

Begging your pardon but the roll out tanks always seem to have lumber or cement blocks along the sides, even though they are clipped to the inside flats. I think accepting solid sides as necessary is probably for the best

you changed my life . now everybody i meet gets to know about kratky hydrophonics . it became a religion haha the way of kratky

Thanks

Thank you! 10 months without a video is way too long!

Very nice your technology

I just use a electrical pipe with a funnel to plant seeds…😊

😃 👍

Thanks.

I have a question Dr Kratky about the impact of varying level of water head on the float valve's ability to maintain the level. Let's say at the start, the supply tank was completely full giving 20" of water head as measured from the bottom of the grow tank and the valve maintained a level of 4" of nutrient in the grow tank. After some time, the supply tank become half empty giving 15" of water head now. Will the float valve still maintain 4" of nutrient in the grow tank in the face of decreased buoyancy pressure requirement to stop the flow from the button dripper ?

Thank You.

Does the 0.6 lb of magnesium sulfate per gallon make a solution of a N:S ratio of 10:6? I want to make sure that I'm maximizing the phenethyl isothiocyanate.

Can you direct me to any research on the air root requirements for various plants? The statement “don’t refill more than a few centimeters” doesn’t match my experience with passive hydroponics. “Leave 1/3 of the root system above the air line” works for me, but goes against all of the advice I can find

Excellent idea - saved me $25.00 + for a factory made float. Made two units, one for the bird bath and one for the fountain.

When looking at the space needed it's probably also important to remember that the people who would grow in bags in a greehouse also probably wouldn't be growing in a field as an alternative but rather in raised beds or grow bags in that same greenhouse requiring the same aisle space.

When my Mother takes up the potato plants(a few days ago) in order to get "New potatoes/"Fresh" potatoes for Swedish "mid summer"(A holiday when this usually happens allover) i use to Re-Plant them with all these Mini spuds on in order to get another harvest later in the summer as i think that it's simply stupid to just let them wilt away when they have so much left to give.

Hi Dr. Kratky, I am a young farmer from the Philippines and a am a big fan of your work. I design systems that are based on your methods; that is, vertical and electricity free. I wish to improve and develop my design to address food shortages and drought problems in my region. I'd like to share my design with you and am hoping to hear your thoughts about it. Would you be open to that? if I could have a way to message you, like an email address, that would be wonderful! Thank you so much for taking the time to read! Cheers, from the Philippines

If put to much nutes might explode and destroy the world 💣🌎

I miss your videos hope all is well

Sir can you share with me what fertilizer went into this. Specifically the NPK and other nutrients and how the solution was made. I'm Basit in Ghana

Put a couple of goldfish in the water - no mosquito’s 👍

Why not let a few plants go to seeds. ?

Doc You mentioned you didn't know why the roots grow up the stem. I think I can help you there. That's so when they're in the river. and say a storm comes. and parts of the plant will break loose. So if they've got roots up the stem, they can then flow downstream, get anchored somewhere further on downstream and carry on growing. That's the way I grow my own watercress in an ebb and flow system. I just break bits off and replace them into another container. So I never really apart from the first time grow them from seeds. And in the past. I've actually bought watercress from the shop. and just submerge that and it throws roots.

Where did you get the tank?

Thanks a lot for the information shared . It's really useful.. can you please help with nutrient details for dilution in water like for preparing Part A and Part B solution

Bernie, the harder you try to get gooder, the worser you get. 😂

Potty pot pot

Because of you Dr. Kratky I'm able to grow Cucumbers without any expensive equipment. It's so easy too.

Aloooha!

Can we use sand as a grow medium?

Can you use Bt?

Great tip

Curious why the outermost pot needs to be any larger / taller than the 5 cm depth of solution that it carries. I would put pot in pot in a big tub and use that as outermost pot for multiple of pot in pots. The outermost post is a saving in this arrangement. This also makes it possible to have pot in pot technique to become pot in grow bag if a grow bag is used. The use of grow bag will be more tolerant to pot bursting.

I prefer this to olla. Ollas may break easily and cost a lot.

Mini glass bottle ? 10ml 😊

I love you Kratky

❤❤❤Thank you for the tip! Very smart, indeed.

Unless if I missed it in this video or the previous part 1, couldn’t this be made to be height variable by drilling a series of holes up the pipe? That way you could pass the wire through and secure it at whatever height hole for your application. This would allow for any heigh within 2” to 24+”. It would require more pipe than necessary on the low end but would make up for that in versatility in my opinion.

Your Kratky system is working Aruba,St Maarten en Suriname. Thanks a lot!

When following these designs learn from my mistakes! Don’t use widely available schedule 40 PVC as 15 mL centrifuge tubes do not fit. I believe schedule 30 by was used in the video which may be a bit harder to find. 1 inch PEXb could serve as a substitute if there is concern for PVC safety, but you sacrifice some rigidity and cost. You could use external crimping or clamping to fix the dripper in place with PEX. 0.5 gph pressure compensating emitters specifications vary by brand, but need higher pressure to function. At an approximate 2 foot pressure differential mine did not flow at all. Still learning as I go!

dang, this is the OG!
