Upside down Pot Growing Methods
HTML-код
- Опубликовано: 5 фев 2021
- An upside-down pot placed in the bottom of a container filled with growing medium provides an air space, saves growing medium and has been shown to increase yields of ginger rhizomes.
Pot-in-pot, pot-in-pot-in-tank and pot-in-pot-in-pot growing methods are discussed. Viewers are encouraged to experiment with upside-down growing methods.

I utilized variations of the pot in pot in pot concept this spring with some tomato and pepper plants I started. It worked out fabulously. The plants loved it and so did I because it made the pots much lighter and easier to handle than if they had been completely filled with growing medium. Plus of course it was nice to save costs on growing medium. Many thanks for the information.
Thanks for trying it out and sharing your experiences!
Dear Dr. Kratky, first let me express my gratitude to you and your efforts, this has helped millions of people worldwide benefit from your technology, both growers and consumers. It came as a big shock for me to have learned about your channel through another YT channel: Keep on Growin' with Mike VanDuzee, who mentioned about your channel and that you are uploading more videos..... I couldn't believe what I heard, it was like, WHATT? I am so grateful and amazed. I have only heard and read about you since I started doing aquaponics/hydroponics. Thank God you are still active, healthy and continuing educating us... May God bless you!!!!
Thank you for you kind comments.
Lots of Pots or POL. This reminds me of the system we used many years ago, around 1990, when I was studying horticulture at my local community college. My Co-op job was taking care of the greenhouses, so I'm very familiar with it. We didn't have the upside down pot in another pot but we did have a coarse growing medium in a pot inside of a tray. Our hort professor used a pinebark perlite mix with ammendments as the growing medium. The majority of plant materials, we had a wide variety, were grown in pots placed in trays which when filled with the water nutrient mix would cover the drainage holes. Usually the tray would be a couple of inches deep or more but that depended on the size of the plant and the size of the pot they were in. For our watering method we had large drums filled with H2O and nutrients that fed into the hoses which then provided a low concentrate constant feed, a typical greenhouse watering situation. The majority of the time, I only filled the trays with water, never top watered, it was like a pseudo hydroponic situation. The growing medium would pull the moisture up to the plants through capillary action. The bark mix provided excellent drainage and air pockets. There were some exceptions to the tray watering method. The epiphytic orchids, amaryllis, poinsettias, some bulbs and cacti come to mind. There were some very large strelitzias and papyrus in 55 gallon drums that I topped water also. We had two greenhouses, (20' x 100', I think) connected by a headhouse which were full most of the time. Being my job, I went into the greenhouses everyday but had to do litlte watering or some days, even no watering. It was very effective and we had little plant loss due to any watering issues. I love your videos.
Thanks for sharing your very interesting greenhouse experience!
Thanks for sharing your knowledge, Dr. Kratky. Your explanations are very didactic and funny. Greetings from Brazil!
Answer? "Illegal" Guess the question's answer depends on location. Nice video, and reflects on how not all crops thrive in a soilless setup. Your data will be useful as I look into building more systems. Keep making videos, it is always a pleasure to watch your videos.
Well, Matt, that wasn't exactly the answer that I was fishing for, but you are absolutely correct for many locations and it is a great answer! I hope you will experiment with the upside-down pot concept and report the results on your youtube channel.
pot in pot in pot in pot. Nice.
I love your videos! You are hilarious and I'm learning! Thank you and Aloha!
Nice demo i use wicking pots and soil doing something similar. Pot in a pot in a pot in a pot on a pot
I've been sitting on this idea for a few days in combination with your float valves and it inspired an idea that i'm going to start working on today. Working title: Compact House Kratky; What it is: A modular system with highly stylized aspects to be used where potted plants are typically put on shelves of varying height. There are 3 basic modules 1) fill reservoir 2)the plant 'pot' 3)the drain reservoir (drain reservoir not necessary but for indoor projects I add backup drains in case float valves fail); How this differs from existing kratky systems: its very similar to the above system but the float valve and drain is worked into the upside down pot of each of the pot modules so it can maintain the minimalist style while being able to place plants on multiple levels and layouts. The beauty of this system is its potential for beauty. As you vary, color and patternize the irrigation tubing between the modules you can conjure up many natural designs. Using my favorite design inspiration (highschool general biology text book) i've come up with some really pleasing designs including things that resemble neuronal connections, kidney blood trasnport diagrams, water falls, plant vasculature diagrams. I think the design i have in my head may fail over time due to roots and float design materials but i think i can work those problems in the next few days. Normally i might try to patent a marketable system like this by in tribute to Dr. K i'd like as many people to make indoor hydroponic systems for their friends. Hydroponics is a gateway drug! Make it the standard for all home and hobby gardeners. Share your designs openly and freely. Dr.Kratky=Love.
You have some great growing ideas and I hope you build some of these designs and share them on youtube!
You can monitor the roots and water level, adjust the level of your drain as your roots grow, leaving that moist air pocket
I just found out that my system already exists lol but super happy to see it works 💪 and I'd call the system cana-pot-in-pot.
Thanks Stan - that's a pretty innovative name!
@@growkratky5558 thanks and thank you for all your hard work to make other people's lives easier. I can only hope to give back to mankind the amount you have.
I love this guy.
Thanks for your innovations! Glad to see you doing videos! What will your next one be about? Love them!
I been getting great results using float valve with the method its amazing
Indeed, Dr Kratky, this is the "Matrioshka Method".
Hello. Im a great fan from the philippines Dr. Kratky. Thank you as always for the ideas you're sharing. I was inspired and started with your Kratky method.
Now my system is Semi- NFT for my lettuce greenhouse. Its NFT when with electricity and becomes Kratky without electricity.
I'm using round 3 " diameter /10 feet PVC pipes and put a drain leaving 1 inch water level when power is out. Lettuces placed just right on a growing cup i just modified(a softdrinks small bottle). It can still keep the lettuce sipping nutrients 2-3 days without power. Frequently we have power interruptions here and i designed it this way but still seeking advise how to keep pvc pipes cool even painted white and covered with insulators.
Im still on a learning stage trying to have better yields w my plants. Combined and incorporate your methods, always been useful and grateful to it.
Will also try this pot in pot method. Thanks a lot.
Brilliant.
Amazing!😍
Amazing
When i think hard about the answer, do i become a "Pot-in-pot-in-pot-in-pot-in-pothead", since there will be so many pots in just 1 sentence?
Yeah, it's a bit overwhelmingly redundant!
Awesome!! Could you go into more detail about growing potatoes in the pot-in-pot-in-tank system? Thanks!
I will look into the possibility of a future youtube as I have some potato data and pictures of interesting related concepts.
@@growkratky5558 Thank you!
@@growkratky5558 I concur with original comment more potatoes, more ginger, more onions. We, as the general public,, DEMAND more subsurface produce! Give the people what they want Dr.K!!!!!
Have been watching lots of videos on Kratky hydroponics on a long cross-country trip from California to Boston. I am keen to try this as my first foray into hydroponics and document my journey on my RUclips channel. Question: how do you respond to the audience who has questions around the nutrient value of hydroponics vs growing in soil?
You are the best! Stay healthy.
Great video, to the point as always!
Don't the roots need to have direct contact with the moist air? What is the idea,of how the moist air helps?
I've been making pot in a pot wicking containers for years, it's the simplest design I could come up with.
Moving the reservoir of water out from beneath the plant to a central location is pretty great.
The hydroponic nutrients I can do without.
Thanks for sharing. Will definitely give it a try.
Hat of Doc. Better than that, ....IMPOSSIBLE!!!
Since they use that method with eggplants then it should works with bell peppers and tomatoes too, right?
Thank you very much for this very interesting video. I found it very interesting to grow plants without worrying about watering.
I have a little query, can we use a nutrient water filled water bottle and place it upside down on the large container touching its opening at the water level.
In this way whenever the water level drops it will work as a little reservoir and fill it again and can be used as a simple fluid level management system.
I haven't tried that, but it sounds like it could work. Thanks for the suggestion!
This pot-in-pot is fascinating. Is the moist air space essentially sealed off from outside air, or can "fresh" air still seep through the growing media/root structure? I'm tempted to put some upside-down pots in my garden to see what happens. One of these days I'm going to put together a float valve and give this a go. I like the shirt!
Please do experiment with this and report it on your youtube channel! I think that a fairly porous growing medium as with a high proportion of perlite will result in more fresh air exchange than if the medium was mostly clay. If there is a lot of interest in this concept, maybe we will design a "Grow ups" t-shirt to provide some company for my friend "Grow Kratky"!
@@growkratky5558 I like it!
Question - Great video by the way - What kind of tubing is used? It looks more flexible than Poly tubing?
It is not conventional polytubing - I bought the tubing from Home Depot some years ago and discarded the label.
Hi I was wondering if there is a reason holes or slots are not cut in the sides of the upside down pot. As this would allow more gas exchange to the roots, even with top up by the float valve keeping a constant water level. I am playing around with a 1 liter plant pot with slots I have cut vertically down the sides (cut with an angle grinder) as the upside down pot with and with out landscape fabric stopping growing media falling through these slots. I'm looking forward to your next video. I would like to see more of your thoughts on growing pot in pot in pot.
You are correct - slots in the sides would be preferred. Thanks for the comment.
Am considering something very similar for large broccoli greens in a 5-gal bucket. Want to use a 10" dia. colander, upside down on the bottom of the bucket, covered with 5" of inert wicking material, and potting mix above that as the growing media. Would provide a maximum 3" water level through a manual fill tube and side drain hole, which would provide minimum 2" air space inside the colander, below the soil. Am considering perlite or small lava rock as the inert wicking material, because I'm concered that potting mix might spoil if it were constantly saturated at the bottom 3 inches. Do you think that concern is valid, or would it be safe to simply cover the colander with potting mix and let it wick itself? Thank you Dr. Kratky you heat my brain.
If I understand what you propose, there is only a small amount of potting mix that is completely saturated and I would try only the potting mix first. However, your wicking material is an interesting idea, and for your own curiosity, you should make up a pot like that and compare with only the potting mix method. Keep thinking!
(1) I thought air roots were a kratky thing. But you seem to be showing with those taros that there's a benefit when plants grow air and water roots, along with original soil roots.
(2) Would watering from the top still create a moist airspace? Or do the pots need to be in a tank/irrigated from below?
The point was that we were trying to borrow from our hydroponic concepts to improve conditions in containers of growing medium. Yes, the upside-down pot from a top-watered pot would have even more air space, because there wouldn't be a water level as in a sub-irrigated pot.
Where did you get the forestry tubes for the. Cucumbers and the accelerator pots from
From Stuewe and Sons located in Oregon.
Gr8 Video !
I am a gr8 fan of your techniques.
I like the pot in pot in pot version in this video - But I have one question: Why is the 2nd inner pot needed (The green one)?
Wouldn't it be easier to throw the inner pot away (The green pot) ? The water-level is already controlled by the float valve and maintain the few inch water-level ?
Thx in advance for your fast response 🙂
This is a special application. Let's say you have a 'show area' where flowers must be in bloom all the time. The plants in the green pots would be growing in a greenhouse (in permanent pots) away from the show area until they bloom. Then they would be placed in the permanent pots in the show area. When they stopped blooming, they would be replaced by new blooming plants.
@@growkratky5558 OK - Got it - Thx for the super fast reply 🙂
If I was growing cannabis in the pot in pot in pot system I'd call it...Tri Pot!
I'm going to try the pot in pot method minus the tubing as I didn't make your float system YET.
I'M using a 5 gallon bucket and a 2-1/2 quart mixing container.
I need to drill the mixing container to replicate the pots style you used as mine has zero holes
My only question is did you have holes where the upside down pot sat in the water?
It is useful to drill some small holes to encourage a few roots to grow into the pots, but not so large that a lot of growing medium falls through the holes.
@@growkratky5558 Thank you. I drilled about 6 to 8 holes. I didn't know if there should be holes at the bottom in the area of the solution.
Going to try and get the adapters to make a float system like yours to water a bucket or two to start.
Thanks again for the response.

Pot x 4 🤣. Thank you dr for the knowledge.
its a potception...
Will you suggested a recipe for growing medium that is suitable for wicking?
The fertilizer used in the 2019 Garden video should work fine -ruclips.net/video/huwgwTHZmPE/видео.html

I have to give you a lot of credit - you came up with a potful of pretty good answers!
Northern Arizona I will be in another severe drought this year. Here is the solution !
I cannot find Pots without drainage holes. Where are you buying these? do they only sell to universities or something?
They can be difficult to find, Some specialty nursery suppliers may bring them in on special order.
Can you use a coir pearlite mix instead of peat?
Yes.
Thanks for the video, very interesting! What is the benefit of maintaining a constant water level, rather than having wet/dry cycles?
Maintaining wet and dry cycles usually requires electric power, a pump, a timer and a separate solution reservoir whereas a constant solution level only requires an elevated supply tank and a float valve.
@@growkratky5558 thanks for your reply. In terms of hand watering, is there any disadvantage to plant growth by letting the media dry out before the next watering? I'm thinking that would avoid an anaerobic zone, but it sounds like that's not a problem. I'm interested in your thoughts, and appreciate you taking the time!
@@compostandconcrete5636 The media can dry out to the extent that it is in a 'moist' zone, but don't approach or surpass the permanent wilting point.
@@growkratky5558 thanks!
Have you compared this to a wicking strategy?
No.
Heaven in a Pot lol
A tesserpot?
I dont know, id say illegal be called.lol take care.thanks for videos.

I'm looking into doing a kratky pepper plant (using the sewerponics method with a float valve). My question is will choosing between a 5, 15, or 55 gallon pot have an affect on my plants size if water level is consistent throughout the entire grow? If so, at what point is the diminishing return for container size to growth ratio in a hydroponic kratky type setup (ignore water quantity as they will be refilled)? The reason I ask is because of videos like this from Peter Stanley. ruclips.net/video/_4ZtodQWwCE/видео.html
If the pot is placed in a tank so the roots can explore more area, then the yield from the 3 pots should be similar. However, if the root space is limited to the pot, then the larger pots would probably yield more, but you will need to do an experiment to actually determine the minimum pot size for optimum yield.
@@growkratky5558 I have one more question. What do you believe to be the optimal water/air ratio in a perpetual kraty setup where water level remains constant. I have a 17.5" tall container and was thinking of setting the water level at 8.75" from the base. This would make the water/air ratio 50/50 for the root zone. Thoughts?
@@aus1046 Yes, that would be a good approach. If plants are growing well, then just leave it that way or you could experiment by slowly dropping the level to as low as 3" from the base.

It would be pot in a pot in a pot in a pot method! Or a 4 pot method. :)
